I purchased the theater system from Best Buy and spent all day Sunday trying to set up/connect the speakers. So today I called Sonos support and spent 4-5 hours trying to coonect to internet even with using an Ethernet cable and was still unsuccessful. I was told it had to be a problem with my network and to call Att. I spent another 2 hours talking with att and they said that since my other devices connect to the internet it must be that the Sonos speakers are defective. I spent a small fortune on their system and am so disappointed that no one can help me. I thought possibly I should buy a different modem/router but don’t know what to buy. Also I do have an echo so possibly thats the problem? I did forget to mention that to tech support. Please help! I don’t want to return but seem no other options.
