Why wont my wireless card connect to my wireless router?

Question

I have a dell Laditude c810 laptop, windows xp. An unnamed wireless card in the side slot. I have a netgear wireless router. All computers will connect to the router wirelessly (I refreshed the factory settings on the router).  without any problem, except my laptop. The laptop's wireless card will connect to ALL wireless routers around my house except mine. It was working just fine until I re-installed windows xp professional. I let windows search the internet for the best driver for the wireless card and everything seems fine.
I just cant figure out why only my laptop wont connect to the router but every other computer can. and why my computer will connect to every other router but mine. It worked just fine before but all it says now is acquiring network address. Please Help! Its driving me nuts.

Its simple really your wireless card is probably not on the same channel as your router to fix this you need to go into device manager-network adapters then right click and select properties for your wireless card there should be a tab that says advanced click it and look for channel number most routers default on channel 6 but if your card is reading its on 6 change it to 11 cause some routers like to throw a twist in and default to channel 11
