My first laptop back in 2005ish or so was a Dell Latitude. Ran XP until Vista came out and I switch to Linux which it ran for a couple years until it was stolen from my car. I recall unimaginable pain and suffering due to wifi, which, IIRC, I side-stepped by buying replacing the stock Broadcom card with an Atheros card and I'm certain is not nearly much of an issue as it used to be.
When it comes to WiFi on Linux, 2005 experiences are irrelevant to today.
2005 is a really long time ago.
