Issue with Network

Relatively new and having issues with internet connectivity.  I have a wifi adapter plugged into the ethernet port and had the network working fine.  I streamed a movie from netflix and all was well.

Tried to go onto the Services tab tonight and I have no content.  I went to Network Settings and refreshed the settings–came back all normal.  Did the Check Connections–all green checks.  Did the Check for Firmware Upgrade and got an error stating could not connect to network.  All Services still out as well.  Any ideas?

Thanks!

Can you post the model and firmware revision of your USB wireless device?
