I've been experiencing a strange issue sometimes with my desktop running Windows 7 Ultimate. Once in a while, when I turn it on, my wireless card will not be detected at all and will not automatically connect to my home network. After a few restarts, it will detect fine on startup and connect to the network.
When it does this and I try to connect, I immediately get a message stating "Windows was unable to connect to ". ipconfig /release and /renew give me the message:
No operation can be performed on Wireless Network Connection while it has its media disconnected.. Sometimes, disabling and re-enabling the Wireless adapter from my Device Manager fixes it. Sometimes, I just have to wait a few minutes and it will automatically try to connect and work.
Any idea what would cause this behavior? Keep in mind it only happens sometimes. Most of the time I can connect just fine on startup, but every so often it'll take about 15 minutes and several restarts before it will be turned on automatically.
