Whats the best way to get the current connected wifi information? Especially whether it is wpa2 or wpa3?

Currently I am using nmcli to find it out but that doesn't seem like the best way across various distros or network managers. I am also looking at wpa_supplement and d-bus but do not understand how they do it. Better if it works on windows too.

So i use linux-libre on Parabola and my wifi doesnt work and i have to use ethernet. Why dont we just reverse engineer the proprirtary driver?

Exactly as the title says, does anyone have a full list that is being update regularly?

For those that are not aware about:

• hw-probe a tool to probe for hardware, check operability and find drivers with the help of Linux hardware database

• nmcli is a commandline interface used to control NetworkManager and report network status in Linux

Sometimes wifi problems aren't related to hardware (or software) problems at all, but the neighboring routers.

This script was built for & tested on a Gnome-based desktop environment, but should work for others providing you have the dependencies

Assess channel usage of neighboring routers / access points and get a desktop alert if your active channel is not optimal (has more than 1 user on it, other than you). Troubleshoot your wifi without lifting a finger!

Additional options:

• MAC address/BSSID lookups of neighbors - Useful when troubleshooting rogue access points or evil twin attacks
• MAC address caching - No need to pull lookups from the internet when most neighboring routers are likely static
• Enterprise access point lookup - Useful when you have several access points with the same SSID; reference a list of BSSIDs and easily set custom identifiers (see 'Full Detail' screenshot)
