Live in a single family home in a neighborhood with relatively close homes - I'm scanning through the wifi channels to decide where to place my 5ghz band. I found when I let the router choose by using "auto" that my connection is rather spotty. I've always had better results in the past by choosing the channel myself.

If the signals i'm seeing from neighbor networks hovering around -75 dBm to -85 dBm at the worst (while mine is around -20 dBm) - am I safe to assume the signal is weak enough where it really does not matter? If I chose a channel that currently has 2 or 3 other networks/hotspots on the same channel but their signal is weak/in that range - the impact is minimal correct? Would increasing to 40 or 80mhz cause any issues?

More bandwidth means better performance, but also that you're more impacted by interference. However if as you said the neighbours are at -75 dBm (or a 55 dB signal to interference ratio) it's really not an issue
