I have a Dell E6400 running Windows 7 Pro and I'm not able to access the internet when connecting to AT&T hot spots. I connect, get an IP adderss, gateway and DNS servers assigned via DHCP but I'm not able to connect to anything and am not able to ping anything, including the default gateway. The network address is 12. x.x.x. I've tried disabling my Norton Internet Security 2011 firewall and also tried booting in Safe Mode with Networking and get the same results. I've also tried running a few commands that were supposed to rebuld my IP4 and IP6 stacks. It almost seems that there's a Windows rule that's blocking access to 12. networks. I'm able to conenct to other wireless networks without a problem... I only have problems with AT&T hotspots that assign 12. IP addresses (I've tried a few different AT&T hot spots at this point). Any ideas appreciated.

Hi, after checking your issue, it seems occur with AT&T hotspots, I suggest you asking AT&T for further help: http://www.att.com/ Please Note: Since the website is not hosted by Microsoft, the link may change without notice.

I started with AT&T and they were able to verify that I was connected to thier network based on my MAC address and verified that the IP address / configuration that was showing with ipconfig was correct but I still wasn't able to ping the gateway. The AT&T tech said that he was not able to see any traffic coming from my computer and that was what lead me to believe that my computer was blocking the traffic and not AT&T.
