Everytime I tried to connect to any wireless network my WiFi got turned off..It didnt even have chance to get to 'connecting' status.Ive just installed winxp sp3 few days ago.Last time it was working,but I cant enable both Internet sharing and firewall..Its an old laptop,compaq,intel inside centrino pentium M 1.5ghz,736mb ram.I know it sucks.Is there anyone able to solve this before I reformat my laptop?
