Hello, I'm trying to use a bluetooth speaker while connected to a wifi. At first, once I started sending something to the speaker via bluetooth, the wifi connection was slowed down a lot or even disconnected because btcoex_enable was not set. Now I enabled it using: modprobe -r ath9k modprobe ath9k btcoex_enable=1 with the result, that I can't connect to the wifi at all, even if bluetooth is completely disabled. Do you know how to fix this?
