I have spoken with AT&T and also Serria wireless. I have a problem when using the air card on Wundows 7 Ultimate 64 bit. When I connect to a customer. I can only get as far as the firewall. I enter all my information and it will connect to the firewall. But if I try to VNC or run remote admin 2 it will never connect. Now with that being said. I can connect if I use a Windows XP machine with no problem. So serria was asking if it could be a Windows 7 setting that was missed. I'm hoping someone can help me out.
