Bought the LG SP11RA soundbar with the wireless sub and rear speakers to go with my 65 LG CX.
Using a Google Nest Wifi with 1 point. The router is in the bedroom with the Opticomm box (Aussie BB 250MB), the point is in the living room about 2 metres from the TV and PS5.
Finally installed the soundbar and rear speakers last night. Soon as I turned them on, they destroyed the WIFI. Netflix went from showing 4k to buffering nonstop. Same with the other apps (Disney, Prime). I'm running the apps directly off the TV, rather than using the PS5 (would that make a difference).
Anything I can do with the Nest Wifi in terms of changing the channels?
Should also note that it's a new Unit, at the Opticomm box are 6 ethernet ports going to different rooms, so I could hardwire the electronics, but none of the ports are marked, so need to figure out which port goes to which room.
SP11RA runs on 5 GHz wireless frequency. Switch your WiFi router to 2.4 GHz if switching channels doesn't help.
If you have the option to hardwire kit, you always should!
