X200 Wifi Solved

[Snort]

I wanted to pass along a problem and solution in case anyone else runs into this problem.

My X200 wifi running Windows 7 would report being connected, but not able to resolve any internet addresses. Wait a minute and it would work. Sometimes, W7 icon would report connected but no internet availalbe (!), then work again. Turn off the wifi switch, reconnect and it would work every time, but resume periodic disconnecting activities. Stream a video for an hour no problem, but switch to a different website and can't connect.

I replaced my Atheros half size card with a used Intel 5100 full size card, and problem solved. W7 reported that the driver didn't install correctly when I booted up, but no errors reported in device manager and it's working fine.

Good luck with your wifi problems, hope this helps someone.
