Hi @Giof
Welcome to the Sonos Community!
I highly recommend you connect a single Sonos device to your network with ethernet permanently to prevent your Sonos speakers from having to utilise your extenders and Sky Q boxes (which act as extenders), if you have any. Extenders are unsupported. Please keep the wired Sonos device and the router 1m apart. If no devices “live” within reach of your main router, you may want to get a Boost, but I recommend testing with a speaker there first to see if a Boost will actually help.
The Beam and the Arc that are affected both seem to be very close to WiFi access points - too close. I appreciate that if these are Sky Q boxes then your options for separating them are somewhat limited, but if they are very close then any increase in separation will help. Again, 1m separation is considered an ideal minimum, but please see what you can do.
If you cannot separate the devices from the access points, you may want to consider disabling 5GHz broadcasts on the access points in question. If these are Sky Q boxes, you’ll need to go into the Engineer’s Menu to do this:
How to access the Sky Q hidden engineers menu
- Press the 'Home' button on your remote control.
- Scroll down to 'Settings' and DO NOT press select.
- Press '001'.
- Press 'Select'
Once in, disable 5GHz in the Network section and apply changes.
You may find some more help/explanation on my troubleshooting article here:
Note: the article describes disabling 2.4GHz on Sky Q boxes, but in your case it’s 5GHz that we want to reduce interference of.
I hope this helps.
