Hello all, this is my first post here. I have 3 SL1 separates and a sub along with a sound bar. I previously had spectrum cable internet which I wasn’t happy with. Now previously before the WiFi update, everything worked perfectly! I upgraded the optical cord to a new one, and it still doesn’t work. I am at my wits end at this point and getting ready to call in to geek squad and see if they’ll do a house call.
