DNS wireless connection problem in Windows 7
New gateway laptop with Windows 7 was connecting to internet for a month, until a few days ago when I started frequently losing the wireless connection.
The only solution was to wait for it to eventually reconnect again.
Other computers are connecting
via wireless with no problem.
I'm getting a message that it's a DNS server issue.
It usually tells me I'm connected to the wireless, but that the connection from the router to the internet is broken.
Wired works fine.
