My wife's phone continually seems to drop it's wireless connection and reverts to 4g in the house. We have pretty good WiFi coverage and where it normally disconnects in the conservatory the signal according to WiFi man is good. The only thing I can narrow it down to is her using a Bluetooth speaker next to her phone. I'm surmising that as they both use 2.4ghz they are interfering. Her phone doesn't have 5ghz wireless. Can anyone suggest anything regards this issue, or if I'm completely on the wrong track.....
