My desktop PC is the only machine in the house having Wi-Fi connectivity issues (connects fine, but drops out randomly after a few minutes or sometimes a few hours)
I think wpa_supplicant is getting confused and thinks signal strength is poor (I have a Netgear mesh, but this seems increasingly common, so it’s weird for that to be the issue)
I did pick up a TP-Link USB Wi-Fi adapter, but can reproduce the same connectivity issues
The fix was switching away from wpa_supplicant in favour of iwd, which seems rock solid in comparison
I’m sure there’s a way to fix wpa_supplicant, but it’s man pages only seem to list the options without actually describing what they do, which seems sort of poor considering how old the project is 🤷
If you can, get yourself a wireless access point instead.
You can connect the computer by ethernet to the access point that then connects to the WiFi network.
By having the device separate you can have it situated away from the computer for better connection and the computer only sees a wired connection.
Plus they tend to be more stable than dongles.
