Hi, I have 2 pc's on a wireless network which seem to connect fine (most of the time) when they start up, but if they sleep/hibernate and sometimes starting up and then try to connect to my network I get limited access - no network connection and when I do the windows 7 troubleshooter It always asks me to reset the wireless device which is I think my router. So I unplug the router, wait 10s and plug it back in and the connection works. How do I fix this problem? I dont want to have to unplug the router everyday. any help would be appreciated.
