Wifi doesn't reach everywhere in my apartment?

Hi Stephanie

I will try to modify the configuration, start disabling the Wifi Steering

1- Log in at: 192.168.0.1 from the web browser of any device.
2- Log in using the following information:

Username: cusadmin
Password: xxxxxxxx (Password you chose during initial setup)

3- Go to the next section to apply changes:

Wireless → General Settings → 5GHz → Band Steering (Disable)

After

Try manually selecting different Wi-Fi channels on your modem

A series of channels are available on each frequency (2.4 and 5 GHz) of your Wi-Fi modem. Interference can have an impact on these channels.
Manually changing the channels used for your Wi-Fi connection can improve your modem’s signal.

1- Connect to your Wi-Fi network.
2- Open the browser on any device, and enter the address 192.168.0.1
3- Log in using these credentials:

Username: cusadmin
Password: (Enter your password, the one you chose when you initially configured your network)

4- In the green bar, select Wireless.
5- Then select:

General settings
5 GHz and/or 2.4 GHz
Wireless channel

6- Select a different channel.

Choose a channel that’s far from the one your modem currently uses, and test it for a few days to see whether things improve or not. Ex. Go from channel 6 to 11. Or, from channel 6 to 1.

If all of this does not help, you have 2 options, put the modem in bridge mode and use your own router or contact the support.
