I am using a verizon air card that can support up to five computers and my Toshiba laptop works fine on it but I also have a Ibm thinkpad that I can not get to work on the card. It give me an connection error and suggest that my firewall setting are why it won't work. It gives like three channels representing Http, hsttp and Tsp or something like that. Can someone please tell how to set it as I'm tired of four of us fighting for my computer. LOL They don't seem to understand how important it is for me to be able to get on TS.com. Thanks for your responses. Jackie B.
