I am not familiar with the Wifi access point that the T-Mobile service 
provides, but I'm taking a guess here. Did you set up these machines on 
a "guest" SSID network or some such setting on the AP? I have found that 
the default configuration in typical home routers for guest networks is 
to isolate clients from each other and only allow access to the WAN. 
This would explain the behavior you are seeing.
