Cindisue-
Again, I'm sorry if I was not clear last night. You can uninstall the EasyTeather on your phone, and on your PC too if you installed anything there. But I have a few questions to see if we can figure this out.
Is your Wireless card a USB card or a built in card? In other words, does the device that actually connects to the wireless live inside the computer or is it pluged into a USB port?
If it is a USB Wireless card, are you plugging the phone into the same group of USB prots as the Wireless? If you are, try connecting to ports on a different part of the computer. For example if it's a desktop, and you have everything pluged into the back of the computer, try pluging the phone into the front of the computer.
Let us know what happens.
