Avast Internet Security 5 blocks internet access in 1 location/not in another.

I installed Avast Internet Security 5 on my Toshiba Satellite. Now, when connecting to the wireless router at my office, it tells me I am connected with a full signal but with “Little or No Connectivity” and does not allow me to connect to the internet or wireless printer in the office. I tried turning off the Firewall, all the Shields, and the Antivirus/Spam portions of AVIS 5 but still have the same problem. When I take my notebook home, it connects seamlessly to my AT&T wireless router and I can connect to the internet easily. I put in a Support Ticket with this same problem and only got back instructions as to how to stop the things I had just told them I had stopped. Anyone have any suggestions? Helpful ones!? ;D

Never mind. Another person in the office brought in a laptop and couldn’t connect either. We re-booted the router and are both connected.
