I am running windows 7. and 3 days ago I got the message "unable to connect to (network name)". and pc went online
1 reinstalled newest driver for my wireless adapter(awus036h)
2. checked to see that my iphone and my other pc that is wired to the router are online
3. updated to latest firmware for router. it's a tp link
4. changed channels on the router.
5. I have no firewalls or encription on my wireless
I find this frustrating because it goes online and offline randomly on it's own. and it had been working fine since I installed it.
