Dlink Network issue

Ok I have a dwl-g520 d-link card and I have a dlink router
A few days ago I was surfing the net and lost connection to the router, ever since then I cannot stay connected to my router.
I have reformatted my computer and still have the problem.
My stepdad in the other room doesn't have any problems staying connected to the router.
I can connect to the router but as I start going through web pages I up and lose connection.
When I do a network router under the name of Jmoney comes up with a network pass on it
after that I have to reboot to be able to get back onto my router.
Also my neighbor has a router under a different network name
If I connect to that router I can stay connected all day no problems.
Any ideas?

 

Well I think the problem with the d-link card is the least of my woes, the last few days ive had everything go bad. Looks like a weak power supply, and crappy wiring is the source of about 95% of my problems in the last month.
