WinXP SP2 supported WPA2 no problem. I'm not sure what this guy is going on about.
Exactly.
Let me get my Commodore 64 on line. Ok it’s online now what? Telnet, no. Ssh, no. Web, no.
Solution looking for a problem (idiot)
XP, at least, can use Supermium, so you could technically browse the internet - although at this point any CPU you have available is going to be quickly overran by simply trying to load modern web pages.
Before that? Unless you have a game or something that needs it, there's really no reason for pre-XP to be anywhere near the internet.
