My home wife is not showing up on my phone or ipad, but still works on my physically wired computer. Does anyone know what is wrong? I have turned on and off several times to see if that fixes it. I used to be able to see it under where you can connect and now it has disappeared. Can anyone help me? Thanks!
Have you tried connecting to the actual router rather than using xFi? Connect to the IP of the xfinity router and login. Go to Gateway->Connection->Wi-Fi. Click EDIT on each of the frequencies and ensure they are enabled. They will show in xFi even if they aren't enabled.
https://internet.xfinity.com/network/advanced-settings/radio will show you mode and channel. It will allow you to edit this info, even if your radios are turned off.
http://10.0.0.1/wireless_network_configuration.php is where you can ensure your ssids are actually broadcasting.
