HTC tethering problem

[hedggie]

Here's the deal, whenever I tether my touch pro to my computer via bluetooth or usb, the phone says "connected" but the computer says "no network access" or "no internet access." Either way I have no connection to the internet. It seems to of only happened today, but I haven't tethered in a while. Also I don't know if you guys know anything about this, but I also have a Huawei EC138 networking usb card from alltel, and it causes my computer to freeze, and the only way to fix it is to unplug the power and start up again. It freezes anywhere between 2-30 minutes after starting connection. I've tried on another computer as well same problem. I have Windows 7, the other has Vista. I've searched the net quite a bit and haven't found anyone with the same problem.
Thanks ahead of time!
