I just received a Sonos speaker as a gift and set it up in my house. I have a FIOS G-1100 router and an Actiontec extender in my house, both with 2.4 GHz and 5 GHz frequencies. I was able to set up while my phone was on 5 GHz and the Sonos on 2.4, but after I moved and re-plugged in the speaker, I can no longer connect to Sonos via the app without switching the phone to the 2.4 GHz frequency.
Sonos suggested disabling an IGMP proxy, but the link I have found to access "hidden" settings produces a 404 error, even after I log in. Looking for the setting within the router setup has not yielded anything either. Is there another way to change this setting, or another suggestion to try?
I wouldn’t use the link. Open you browser and type 192.168.1.1 or myfiosgateway.com and the admin password is on the sticker. Once in the router up to the right click the “Advanced” tab and it is under “Network Settings”.
