First off rather long and not sure if its in the right spot

Hi all people with more knowledge than me am trying to connect to a wireless network in house (I share a house) and the others can all use the network fine (from 3 different laptops). The network has been up for about a week now with no problems to them. 1st problem was I didn’t have the aegis protocol installed but that has been fixed, the aegis client (version 2.2.1.0) is now able to secure the connection so the password is correct, windows connection utility states connection established, Network Stumbler also is able to get a connection to the router.
And any other wireless network that I get to is able to connect fine

Even I have all this to confirm that the connection is proper, I am unable to ping anything over the network including the router and any of the other laptops, the same thing happens when a GPRS/wireless adaptor is used to connect to the network.

What I’ve done (not in order) includes updating my drivers, reinstalling SP2 only (not a complete reinstall of the OS), using a static IP address, copying network settings from a laptop that works using windows utilities, placing the laptop next to one that works and double checking the settings on both the card and the network, checking with the router that my ip/mac address is not blocked on the router. I am at a complete loss with what else to do and any help that u can give me would be greatly appreciated

Probably not important but the ram controller, ram, GPRS/wireless PCMCIA card all got destroyed in a power serge and motherboard, ram and card were all replaced about a month ago.

Some other info that will be needed include
The router is a netgear wpn 802
Security is wpa-psk
Encryption is tkip
All laptops are running XP Pro SP2
