I have 2 speakers in my system -- a Play:1 and a One SL. The Play:1 works flawlessly. The One SL initially worked well, then after a few months, started dropping the wifi connection. For a while, I was able to reset the speaker and get it working, but now I am unable to get the speaker to work on wifi. I am able to get it working on ethernet, but the room I want the speaker in is NOT in the room where the router is located. I need both speakers to be able to work via wifi.
I ran a diagnostic with the One SL wired (ethernet) and the Play:1 wireless - 392211954
And another after attempting to switch to wireless, with just the Play:1 working - 929129918
