I've got a 3B+ which I'm using connected to a BTWholeHome mesh system. This supports 2.5ghz and 5ghz but it only has one SSID, unlike my router which has one for 2.4 and one for 5. So I can't just select the SSID I want.
The Pi is quite far away and through an internal wall but it connects at 5ghz. It's running a security camera and the streaming is really flaky. I've got a Pi Zero which is about the same distance away with an external wall and an internal wall in the way but it streams really well.
The 3B+ is seeing -63dBm
The Zero is seeing -68dBm
You'd think the 3B+ would perform better???
I'm wondering if I'd be better off forcing the 3B+ to use 2.4ghz but I can't find a way to do this.
Would I see a decent improvement by switching to a USB wifi adapter?
