Laptop Wireless Network Logon To Domain Help

[browny2k4]

hello there i have a Laptop With a D-Link WIFI PCMIA Card and the laptop has no Lan card installed so my only way to connect to my Router is via loging onto my local account on the Laptops harddrive but i want to make my home network to every computer has to logon over the network but everytime i try to on the laptop it cannot connect as the WIFI connection to the router is not connected but when i use a LAN cable on any of the other PC's it works fine.

I have searched for a few hours and found no solution so any help would be greatly appreciated.

All The systems have XP Pro with Service pack 2

thanks
