I know all the helpful members who try to diagnose/resolve network issues hang out here. I think I dreamt up a really useful network info command today. This command returns only the essential info and removes all the cruft from the super long hwinfo output.
hwinfo --netcard --wlan --bluetooth | grep -Ei "model\:|driver\:|status\:|cmd\:|file\:|detected\:" | grep -v "Config Status"
Try it and give me some feedback.
Please feel free to use it if you like it.
Here are links to other useful scripts/commands that I added later on in this thread that are useful for troubleshooting network issues.
Command to search for recently updated components that can affect networking:
Command to install the linux-headers for every installed kernel:
Command to disable MAC Adress Randomization:
