Oh god I remember that. Luckily in 2003 my main computer was scraped together from discarded parts at my father's day job, so it was ethernet only

In 2024 on a laptop I still have wifi problems though. Most recently, if I closed and opened the laptop lid (suspend + resume), the wifi hardware just disappeared off the face of the kernel.

Turns out that the iwlwifi kernel module just irreversibly crashes when the laptop suspends and can only be fixed with a reboot.

So I had the fun task learning about systemd pre-suspend hooks to unload the driver before suspend and load it again on resume.

Turns out wifi drivers still suck in 2024
