I've been helping a friend of mine set his new laptop up, and I ran into an issue when I tried to connect to my wireless network. It attempts to connect, then just hangs there. I've tested this on multiple routers. And every time, after a few seconds, it says "No Internet Connection." The internet works when I use an ethernet cable, but not wirelessly. I tried all of the fixes I could find. Disabling ipv6, resetting my router to factory default settings, uninstalling and reinstalling drivers, etc. I even reinstalled Windows 7 with my Window Ultimate install disc (I figured that maybe he had gotten a bad install) and I still had no luck. When I tried pinging the router's IP address (192.168.1.1) and got: Pinging 192.168.1.1 with 32 bytes of data: Reply from 192.168.1.5: Destination host unreachable.

Ping statistics for 192.168.1.1: Packets: Sent = 4, Received = 4, Lost = 0(0% loss) The model of the card is Railink RT5390. The router is an Arris router/modem combo and was supplied to me by Comcast. Tell me if I need to supply more information. Is it possible that it's a bad WLAN card?
