Suddenly WiFi signal strength is poor
08-20-2021, 05:25 AM
The WiFi signal strength has become very poor on my Pinephone. I suspect it is a hardware issue and I’m looking for some pointers on how to diagnose the problem.
Some data points using wavemon:
PinePhone (approx 6ft away): -86 dBm, quality 33%
PinePhone (approx 1ft away): -62 dBm, quality 70%
Laptop (approx 6ft away): -39 dBm, quality 100%
I understand that the antenna connects from the mainboard to the inner frame which has the antenna on it. I put pressure on that corner of the phone to see if it may not have made a good connection to the case but that doesn’t seem to change the signal strength. I’ve taken the inner frame off to try and reseat it but that didn’t show any improvement.
Is there a way I can narrow the problem down to the case, the mainboard, or the connection between them? Any tips?
