User:Szucsatti/wireless connection problem

I have a had a problem with configuring the wireless connection on a Sony Vaio laptop. I have a wireless router, to which two computers are already connected. I have freshly installed Windows Xp on the Sony laptop and I couldn't try the wireless connection. I have renewed the network connection with ipconfig /renew but it said "Unavle to contact your DHCP server". I have checked my DHCP service and it was working. I have downloaded the little network fix programs recommended by several sites (Lspfix & WinsockxpFix), but none of them worked. I have finally found a forum thread that answered my problem. I turned the password protection off on the router and woala...the connection was established. After turning the password protection on, I could connect to the router without any problems. I still don't know the reason, but at least it worked for me.
