Installation

How do I install the Fiber Box with home network cabling?

If your home has home network cabling with a multimedia (or distribution) cabinet, this multimedia cabinet is often positioned at the entrance of the home. You can place your Fiber Box in the multimedia cabinet or on the outside.
We recommend placing the Fiber Box in the multimedia cabinet, particularly to connect the Fiber Box to the home network cabling.

If the size of the multimedia cabinet is large enough to store the Fiber Box and proper ventilation of the Fiber Box is ensured, place the Fiber Box inside the multimedia cabinet.

Then connect:

(1) The power supply of the Fibre Box to a power outlet.
(2) The optical cable to the optical outlet located in the multimedia cabinet, on the port used by Salt Home (the port number is indicated in the e-mail and the SMS informing about the activation of your Salt Home services) and (3) to the F-port of the Fiber Box.

Figure 1 - Installation diagram of the Salt Fiber Box

When connecting the optical cable to the F-port of the Fiber Box, ensure that the blue lever on the connector is locked and plugged in and points upwards (see figure 2).

Figure 2 - Blue lever locked and plugged in, pointing upwards

Then connect:

An RJ45 (Ethernet) cable between an Ethernet port (port D) of the Fiber Box and each Ethernet socket on the switchboard corresponding to a room to be connected. Note that only one cable is provided.
Connect an RJ11 (telephone) cable between a telephone port (port C) of the Fiber Box (use the RJ11-TT83 adapter) and an RJ11 socket on the switchboard corresponding to a room where the telephone will be connected.
Alternative: a DECT telephone can be connected to the Fiber Box, assuming there is a sufficient signal between the Fiber Box and the telephone.

Figure 3 - Ports of the Salt Fiber Box

Attention:

If the Fiber Box is placed in a multimedia cabinet, the Wi-Fi signal will be weakened. We therefore recommend extending the Wi-Fi range with a Wi-Fi repeater, available on this page.

The Smart Wi-Fi Extender must be within range of the Wi-Fi signal of the Fibre Box. When the blue LED is lit, the Smart Wi-Fi Extender is on. When the orange LED is on, the Smart Wi-Fi Extender must be placed closer to the Fibre Box.

The Smart Wi-Fi Extender can also be connected by cable, which improves the stability of the transmission. See Smart Wi-Fi Extender Quick Start Guide for more details.

The location and position of the Fiber Box in your home is crucial.

Place your Fiber Box in a central position in your home. This will allow you to receive Wi-Fi from different parts of your home.
Depending on the size of the home, we recommend using the Smart Wi-Fi Extender to extend the Fiber Box's Wi-Fi signal and thus benefit from a reliable Wi-Fi signal in areas of the house where the Fiber Box's signal is weak.
Place your Fiber Box horizontally. Do not place the Fiber Box behind, under or on top of the TV set or a piece of furniture, as this will reduce the Wi-Fi range. View all our "Tips & Tricks" to optimise and increase the performance of your Fiber Box on this page.

If you have a multimedia cabinet

Connect one end of the optical fibre cable (in the form of a triangle) to the optical outlet located in the multimedia cabinet on the port used by Salt Home (you will find the port number to be used in your personal account My Account or in the email that informed you of the activation of the service).
Connect the other end of the optical fibre cable (connector with square end) to the Fibre Box (Attention: the blue lever on the connector of the Fibre Box must point upwards and make sure that the connector is locked and plugged in), in the F-port. Remove the protection of the F-port (black rubber) and the protective caps (green plugs) at both ends of the optical fibre cable.

Handle the optical fibre cable carefully, as it is very fragile.

Connect the power supply of the Fibre Box to a power outlet and to the Fibre Box.

During the synchronisation phase the POWER LED lights up and the FIBER LED blinks. When the FIBER LED stops blinking, your Fiber Box is synchronized. This process can take up to 10 minutes.

Connecting the Apple TV, a computer or a game console

You can connect your devices to the Fiber Box via Ethernet cable (RJ45) or via the Wi-Fi signal.

Ethernet cable:

Connect an Ethernet cable to an RJ45 port (Port D) on the Fibre Box and to the RJ45 port on your device. We recommend this configuration for optimum quality of service. We recommend this configuration for optimal quality of service, especially for online video games.

Wi-Fi :

Activate Wi-Fi on the Fiber Box by briefly pressing the WLAN button:
The Fiber Box provides 2 Wi-Fi bands for more flexibility and better performance. You will see the following Wi-Fi networks with your devices:
- Salt_2Ghz_SSID_NAME_OF_YOUR_BOX
- Salt_5Ghz_SSID_NAME_OF_YOUR_BOX

Use one or the other, bearing in mind that the 5Ghz Wi-Fi network is faster but more sensitive to obstacles (e.g. walls): Choose the 5Ghz network if your device is in the same room or relatively close by, or if the 2.4Ghz band is congested (you will see several Wi-Fi networks on your device).

You can also use the WPS function by pressing and holding the WLAN button (approx. 5s) until the green WPS LED lights up and blinks.

The WPS function allows you to easily connect to the Wi-Fi network.

Connecting a smartphone or tablet

You can connect a smartphone or tablet via Wi-Fi, as explained in the section above "Connecting the Apple TV, a computer or a game console".

For help in setting up Wi-Fi on a smartphone or tablet, refer to our Device help and support page.

Connecting a telephone

You can connect a telephone either via an RJ11 cable or via the wireless DECT function of the Fibre Box:

RJ11 cable (telephone cable)
- Connect an RJ11 (telephone) cable between a telephone port ( Port C) of the Fiber Box (use the RJ11-TT83 adapter) and the telephone.

The Fibre Box is equipped with 2 telephone ports, which allows the use of 2 telephones (this is relevant if the Fibre Box is installed in a multimedia cabinet with a distributor).

DECT (wireless)
- Connect a cordless DECT telephone to the Fibre Box, assuming there is a sufficient signal between the Fibre Box and the telephone. Press the DECT key on the Fibre Box for more than 5 seconds. Your DECT telephone can then pair up with the Fibre Box. To test the DECT pairing, briefly press the DECT key and your telephone should ring.

Wi-Fi

How can I change the Wi-Fi name and password?

Connect to the administration console.
Change the view from "Standard" to "Expert".
Select the menu of the WLAN bandwidth (2.4GHz or 5GHz) of which you want to change the name and/or password:
- you can change the Wi-Fi name in the editable field next to SSID.
- you can change the Wi-Fi password in the editable field next to WPA-PreShared Key.
- Use any combination of letters, numbers and special characters (?!%+ etc.) as well as upper and lower case.
- Do not use special characters such as ä, é, à, ñ, ç or §.
Confirm the changes by clicking on "Save settings".

After successfully changing the name or password, you must connect your devices to the Wi-Fi network again.

How can I change the Wi-Fi channel (5Ghz, 2.4Ghz) used by the Fiber Box?

Please note that the Fiber Box is equipped with a mechanism which automatically changes channels if it detects that the channel being used is disturbed. Changing the channel manually is therefore not recommended.
However, if you wish to manually configure the channel of your Wi-Fi networks, we advise you to use an application such as Wi-Fi Analyzer on your mobile phone to identify the least disturbed channels.

Open your Internet browser and enter the URL http://salt.box or the IP address 192.168.1.1.
Change the view from "Standard" to "Expert".
Select the "WLAN" menu on the left and then the "2.4GHz" tab.
Under "Channel", choose between the channels 1, 6 and 11.
Select the "WLAN" menu on the left and then the "5GHz" tab.
Under "Channel", select the desired channel.
Deactivate the 2.4GHz channel. In the "WLAN" menu, "Smart Wi-Fi" tab, select "OFF" next to the "Enable SSID" field.
Deactivate the 5GHz channel. In the "WLAN" menu, "Smart Wi-Fi" tab, select "OFF" next to the "Enable SSID" field.

How do I turn the Wi-Fi on and off in the administration console?

Connect to the administration console.
Change the view from "Standard" to "Expert.
Under "WLAN" go to "Smart Wi-Fi".
Click the button displayed under the connected Wi-Fi network next to the SSID field.
- When ON is displayed next to the SSID field, the WLAN is turned on.
- When OFF is displayed next to the SSID field, the WLAN is turned off.

Should I rather use the 5 Ghz (Salt_5Ghz_SSID_NAME_OF_YOUR_BOX) frequency band or the 2.4 GHz (Salt_2.4Ghz_SSID_NAME_OF_YOUR_BOX) frequency band?

The 5 GHz frequency band operates in a frequency band that is less used, and therefore less disturbed, than the 2.4 GHz frequency band. The latter is used by many devices such as microwaves, surveillance cameras, Bluetooth devices, etc. and of course by the neighbour’s Wi-Fi network.

The 5 GHz frequency band also allows a higher throughput. However, its coverage is lower and it is more difficult to cross obstacles (walls, concrete floors, aquariums, etc.).

If your device only supports the 2.4 GHz frequency, you will not be able to select the 5 GHz frequency.

Should your device support both frequencies, then we recommend that you configure your device for both networks:

Search for Wi-Fi networks on your device and connect to each of the two Salt Wi-Fi networks by entering the corresponding password. Connect to the first one, disconnect and then connect to the second one.
Allow the device to automatically choose the Wi-Fi network depending on its distance from the Fiber Box.

Note: see below for information about specific devices such as the Apple TV.

Further information

You can also configure your devices depending on how you use them:

For a device that is placed within range of the 5 GHz Wi-Fi signal (e.g. Apple TV), we recommend connecting it only to the 5 GHz Wi-Fi. If you are also connected to the 2.4 GHz Wi-Fi, you may encounter stability issues.

Note: We recommend connecting the Apple TV via the Ethernet cable for optimal stability. This also applies to game consoles. If your device is connected via Ethernet, ensure it is not also connected via Wi-Fi as this may affect the stability of your connection.

For a device that you are going to move around your home (e.g. mobile phone, tablet), we recommend that you mainly use the 2.4 GHz frequency band.

Should the Wi-Fi frequency band (2.4 GHz) be congested, you can also change channels. (cf. How can I change the Wi-Fi channel (5 GHz, 2.4 GHz) used by the Fiber Box?)

What is Airtime Fairness, and how do I enable / disable it?

Airtime fairness is a function on many routers which allows for better overall performance, especially if a large number of devices are connected. However, sometimes older and slower devices don’t function well when it’s enabled.

Fiber Box X6 (black)

Connect to the administration console.
Under “Wi-Fi” go to “Advanced”.

Activate or deactivate “Airtime Fairness” on one or both Wi-Fi bands.

Click on “Apply” and restart your router.

Fiber Box (white)

Connect to the administration console.
Change the view from “Standard” to “Advanced”.
Select the WLAN menu.
In the tab “WLAN 2.4GHz”, under “Airtime Fairness” select “Enable” or “Disable”.

Save your settings.
Repeat on the 5GHz network.
Apply the changes.
Restart your router.

What is Band Steering, and how do I enable / disable it?

Band steering is a function on many modern routers which allows for optimal network performance with little effort on the user’s part. However, certain devices don’t handle it as well as others. This can cause performance issues, which can be solved by disabling band steering.

Fiber Box X6 (black)

Enable or disable band steering for a specific device

Open your administration console and select “Standard” view.
Navigate to the tab “Client List” of the “Wi-Fi” menu.

Locate the device for which you wish to activate or deactivate band steering in the list.

Check or uncheck the highlighted box to enable or disable band steering for any device which has been previously connected to your router.
Finally, restart your router.

Enable or disable band steering entirely

Open your administration console and go to the “Wi-Fi” menu, then to the tab “Band-Steering”.
Once you do so, you will see two different networks (one for each band) in the “Basic” tab.
- If you don’t change the names of these networks, your device will choose which one to connect to itself (i.e. band steering will be enabled).
If you want two separate networks (i.e. to disable band steering), change the name of each band (by adding “2.4GHz” to the 2.4GHz network and “5GHz” to the 5GHz one, for example).
Finally, restart your router.

Gigabox (AX3 router)

Enable or disable band steering entirely

Connect to the administration console and navigate to the “My Wi-Fi” tab.
Deselect “Prioritize 5 GHz” to disable band steering, or select it to enable it.

If you disabled band steering, you will then be able to configure separate bands by navigating to “More functions” → ”Wi-Fi settings” → ”Advanced Wi-Fi settings”.

Troubleshooting

Connection

I have no internet connection, what should I do?

If you are unable to connect your devices via Wi-Fi or via Ethernet cable, please visit the page fiber.salt.ch/internet/trouble. Performing the verification steps indicated will allow you to solve the most frequent connection problems.

I don't have or no longer have an Ethernet connection with my device, what should I do?

If your device is connected through a switch, connect it directly to the Fiber Box. If your device works without being connected through the switch, replace your switch or contact the manufacturer.
If there are other devices connected to your Fiber Box via Ethernet, unplug them. Also, turn off the Wi-Fi (see How do I turn the Wi-Fi on and off in the administration console?).
If your device is working properly, there is probably an IP address conflict on your network. Check the network configuration of your device and use automatic addressing (DHCP) rather than manual addressing. If you intend to use a fixed IP address, use an unused address outside the address range used by the DHCP server.
Connect your device to another Ethernet port.
If this solves the problem, connect another device to the Ethernet port that does not work.
If the Ethernet port does not work with different devices, use the other available Ethernet ports. If you need all the Ethernet ports to connect your devices, contact us at 0800 700 500.
Test your device with another Ethernet cable.
Test the Ethernet connection with another device, such as Apple TV.
If it works, it means that there is a problem with your initial device.
Reset the device to the factory settings.
If this does not work, please contact the manufacturer.
Reset the Fiber Box to the factory settings (see How can I perform a reset of my Salt Fiber Box?).
If you are using an Internet repeater that is not commercialised by Salt Home, it may be the cause of your Ethernet connection problem. To fix it, follow the configuration steps below:
- Connect to the administration console of your Salt Fiber Box.
- Change the view from "Standard" to "Expert".
- Go to "Smart Wi-Fi" → "WLAN".
- Disable the "Mesh" function.

If this does not solve the problem, please contact us at 0800 700 500.

I have no internet connection with my device when connected to Wi-Fi, what should I do?

On a smartphone:

If you have an old smartphone (eg. Redmi 7) and you are unable to connect to Wi-Fi, please reset your Fiber Box. Visit the FAQ section How can I perform a reset of my Salt Fiber Box? and follow the reset instructions.

On your Salt Fiber Box:

The loss of Wi-Fi connection is mainly caused by the following factors:

1. Router

If you are using a Wi-Fi router in addition to your Salt Fiber Box, please unplug it and connect directly to the Fiber Box's Wi-Fi.

If you are now able to establish a Wi-Fi connection, it is very likely that the problem is due to the router. In this case, follow the troubleshooting procedure of the router.

Our technical teams also provide support for equipment that was not purchased at Salt. This service will be charged.

2. Repeaters

If you are using (a) Wi-Fi repeater(s), please disconnect it (them).

If you are now able to establish a Wi-Fi connection, follow the troubleshooting procedure of your repeater. If the repeater was supplied by Salt, please refer to the page Smart Wi-Fi Extender.

Please make sure that the Wi-Fi repeater is installed between the Fiber Box and the connected device, so that it receives the signal from both the Fiber Box and the connected device.

3. Signal

Use your device for a certain time (about 3 min.) near the Fiber Box (2 meters max.) to check the connectivity of the device.

If the device is now able to connect to the Internet, your device was previously too far away from the Fiber Box and was not receiving the Wi-Fi signal optimally.

Make sure not to place the Fiber Box behind or under your TV set nor in close proximity to any metal object or aquarium. Please also install the Fiber Box horizontally and, if possible, on a raised surface.

If you install the Fiber Box inside a multimedia cabinet with a metal door, you can place a Wi-Fi repeater nearby to increase the signal strength.

In general, you can use Wi-Fi repeaters in every corner of your home to amplify the Wi-Fi signal.

You can find more recommendations concerning the installation of the Fiber Box on our page Wi-Fi Tips & Tricks.

4. Device status

Restart your device and the Fiber Box (unplug the power supply of the Fiber Box for 15 seconds and then plug it back in).

If, after the restart, both the device and the Fiber Box connect to the Wi-Fi network, the connectivity issue was due to the device status.

If the problem persists or reoccurs, please check the Wi-Fi connection with other devices (in particular with the Apple TV if you have obtained one from Salt). If the problem occurs only with one device, it probably needs to be reset, repaired or replaced (check the device specifications or contact the manufacturer's technical support).

5. Wi-Fi Networks status

The Fiber Box supports two Wi-Fi networks using two different frequency bands.

Check on several devices (in particular with the Apple TV if you have obtained one from Salt) that these two Wi-Fi networks are active:

Salt_2Ghz_SSID_NAME_OF_YOUR_BOX
Salt_5Ghz_SSID_NAME_OF_YOUR_BOX

Note: Not all devices can detect the Salt_5Ghz_SSID_NAME_OF_YOUR_BOX frequency band. Please check your device's manual to make sure it actually supports the 5 GHz Wi-Fi. The Apple TV supports both frequencies; therefore, you should be able to see both networks on it.

Is one or both networks not active?

Activate the Wi-Fi connection on your Fiber Box:

Connect to the administration console of the Fiber Box and activate the missing Wi-Fi network(s). See How can I change the Wi-Fi channel (5 GHz, 2.4 GHz) used by the Fiber Box?

Reset the Fiber Box. See How can I perform a reset of my Salt Fiber Box?
Then activate the Wi-Fi connection by briefly pressing the WLAN button.

6. Connection to Wi-Fi networks

Reset your device's connection to the Wi-Fi networks

Remove the networks Salt_2Ghz_SSID_NAME_OF_YOUR_BOX and Salt_5Ghz_SSID_NAME_OF_YOUR_BOX Wi-Fi on your device.
Connect to the first Wi-Fi network (i.e. Salt_2Ghz).
Disconnect from the first Wi-Fi network.
Connect to the second network (i.e. Salt_5Ghz).

You can also reset all network settings on your device (see your device's manual) or visit our Device help and support page.

7. Wi-Fi password

Update or reset the password of the Wi-Fi networks:

Connect to the administration console of the Fiber Box and change the password. See How can I change the Wi-Fi name and password?

Reset the Fiber Box. See How can I perform a reset of my Salt Fiber Box?
If the WLAN LED is off, activate the Wi-Fi connection by briefly pressing the WLAN button. The default password is displayed on the label at the bottom of the Fiber Box.

8. IP address conflict

Disconnect all devices connected to the Ethernet ports of the Fiber Box.

Change the password of both Wi-Fi networks (5Ghz Wi-Fi and 2.4Gh).

Set the new password only on the device having connectivity problems and use it for a sufficiently long time to check if the device is connected properly.

If the problem is solved, it was due to an IP address conflict. Check the network configuration of your devices and use automatic addressing (DHCP) rather than manual addressing. If you want to use a fixed IP address, choose an unused address outside the address range used by the DHCP server (See FAQ section Advanced settings).

Search the devices connected to your Fiber Box (including via LAN) in the administration console in order to connect them all (See FAQ section How do I know if the connected device is recognized by the Fiber Box?).

9. Wi-Fi band

If your device is connected to the network Salt_2Ghz_SSID_UNDER_YOUR_BOX, connect it to the network Salt_5Ghz_SSID_UNDER_YOUR_BOX and vice-versa.

If only one of the two networks is visible, you can either:

Log on to the administration console of the Fiber Box and activate the missing Wi-Fi network.

Reset the Fiber Box and activate Wi-Fi by briefly pressing the WLAN button.

If the problem is solved, the Wi-Fi network was congested or disrupted. We recommend that you use the Wi-Fi network that works best with your device.

Note: Not all devices can detect the frequency band Salt_5Ghz_SSID_NAME_OF_YOUR_BOX. Read your device's manual to ensure that it supports 5 GHz Wi-Fi. The Apple TV supports both frequencies, so you should be able to see both networks on it.

My device has slow Wi-Fi connection, what should I do?

Common causes of a slow Wi-Fi connection are the following:

1. The limitation of the device used

Perform a speed test on your device (ex. use the app Speedtest by Ookla on a smartphone, tablet, Apple TV, other connected TV, etc.). On a computer, enter https://www.speedtest.net/server/salt in a browser.

Note: if your test results are at least 20 Mbps, your Internet speed is sufficient!

If the speed is not satisfactory, follow the next steps.

2. Router

If you are using a Wi-Fi router in addition to your Salt Fiber Box, please unplug it and connect directly to the Fiber Box's Wi-Fi.

If you are now able to establish a Wi-Fi connection, it is very likely that the problem is due to the router. In this case, follow the troubleshooting procedure of the router.

Our technical teams also provide support for equipment that was not purchased at Salt. This service will be charged.

3. Repeaters

If you are using (a) Wi-Fi repeater(s), please disconnect it (them).

If you are now able to establish a Wi-Fi connection, follow the troubleshooting procedure of your repeater. If the repeater was supplied by Salt, please refer to the page Smart Wi-Fi Extender.

Please make sure that the Wi-Fi repeater is installed between the Fiber Box and the connected device, so that it receives the signal from both the Fiber Box and the connected device.

4. Signal

Use your device for a certain time (about 3 min.) near the Fiber Box (2 meters max.) to check the connectivity of the device.

If the device is now able to connect to the Internet, your device was previously too far away from the Fiber Box and was not receiving the Wi-Fi signal optimally.

If you install the Fiber Box inside a multimedia cabinet with a metal door, you can place a Wi-Fi repeater nearby to increase the signal strength.

In general, you can use Wi-Fi repeaters in every corner of your home to amplify the Wi-Fi signal.

You can find more recommendations concerning the installation of the Fiber Box on our page Wi-Fi Tips & Tricks.

5. Device status

Restart your device and the Fiber Box (unplug the power supply of the Fiber Box for 15 seconds and then plug it back in).

If, after the restart, both the device and the Fiber Box connect to the Wi-Fi network, the connectivity issue was due to the device status.

6. Wi-Fi band

If your device is connected to the network Salt_2Ghz_SSID_UNDER_YOUR_BOX, connect it to the network Salt_5Ghz_SSID_UNDER_YOUR_BOX and vice-versa.

If only one of the two networks is visible, you can either:

Log on to the administration console of the Fiber Box and activate the missing Wi-Fi network.
OR
Reset the Fiber Box and activate Wi-Fi by briefly pressing the WLAN button.

If the problem is solved, the Wi-Fi network was congested or disrupted. We recommend that you use the Wi-Fi network that works best with your device.

7. The device used

Carry out a speed test with another device, ideally with the Apple TV supplied by Salt if you have chosen this option.

As before, follow the steps to perform the tests in the best possible conditions (near the Fibre Box, change the Wi-Fi band and restart the device if necessary, do not connect any other routers or Wi-Fi repeaters).

If the test is satisfactory with the other devices, the problem originates from your device. Consult the instructions of your device, reset it or contact the manufacturer's support.

My device keeps dropping out of the Wi-Fi connection, what should I do?

The loss of Wi-Fi connection is mainly caused by the following factors:

1. Router

If you are using a Wi-Fi router in addition to your Salt Fiber Box, please unplug it and connect directly to the Fiber Box's Wi-Fi.

If you are now able to establish a Wi-Fi connection, it is very likely that the problem is due to the router. In this case, follow the troubleshooting procedure of the router.

Our technical teams also provide support for equipment that was not purchased at Salt. This service will be charged.

2. Repeaters

If you are using (a) Wi-Fi repeater(s), please disconnect it (them).

If you are now able to establish a Wi-Fi connection, follow the troubleshooting procedure of your repeater. If the repeater was supplied by Salt, please refer to the page Smart Wi-Fi Extender.

Please make sure that the Wi-Fi repeater is installed between the Fiber Box and the connected device, so that it receives the signal from both the Fiber Box and the connected device.

3. Signal

Use your device for a certain time (about 3 min.) near the Fiber Box (2 meters max.) to check the connectivity of the device.

If the device is now able to connect to the Internet, your device was previously too far away from the Fiber Box and was not receiving the Wi-Fi signal optimally.

If you install the Fiber Box inside a multimedia cabinet with a metal door, you can place a Wi-Fi repeater nearby to increase the signal strength.

In general, you can use Wi-Fi repeaters in every corner of your home to amplify the Wi-Fi signal.

You can find more recommendations concerning the installation of the Fiber Box on our page Wi-Fi Tips & Tricks.

4. Device status

Restart your device and the Fiber Box (unplug the power supply of the Fiber Box for 15 seconds and then plug it back in).

If, after the restart, both the device and the Fiber Box connect to the Wi-Fi network, the connectivity issue was due to the device status.

5. IP address conflict

Disconnect all devices connected to the Ethernet ports of the Fiber Box.

Change the password of both Wi-Fi networks (5Ghz Wi-Fi and 2.4Gh).

Set the new password only on the device having connectivity problems and use it for a sufficiently long time to check if the device is connected properly.

6. Wi-Fi band

If your device is connected to the network Salt_2Ghz_SSID_UNDER_YOUR_BOX, connect it to the network Salt_5Ghz_SSID_UNDER_YOUR_BOX and vice-versa.

If only one of the two networks is visible, you can either:

Log on to the administration console of the Fiber Box and activate the missing Wi-Fi network.
OR
Reset the Fiber Box and activate Wi-Fi by briefly pressing the WLAN button.

If the problem is solved, the Wi-Fi network was congested or disrupted. We recommend that you use the Wi-Fi network that works best with your device.

Damaged equipment

I damaged my Salt Fiber Box, how should I proceed?

In case of damage, loss or theft of your Salt Fiber Box, contact our customer care and request a new one. A charge of CHF 199.- will be added to your next monthly bill.
