I am having the same problem, but I am not sure how to change the SSID name as previous posts have recommended. When I click on properties for my network the name under SSID is grayed out. The ones I can change are Network Authentication (currently set to WPA-PSK) and Data encyption (currently set to TKIP).

My wireless network was working fine and then went on vacation for a week. When I powered things back up, I've been getting the Acquiring Network Address loop that leads to Limited or no Connectivity.

Thanks for any help.
