100. What is it? I just upgraded my USB modem from Verizon to the new 4G UML 290. My mom and I both had problems connecting at first but the tech at our local store fixed hers and said it had something to do with us running Windows Vista. So the tech said for me to uninstall the old modem and software, reboot the computer, then install the new modem and software. So I did and now when I hit the "Connect" button I get a message that says "Device could not establish a connection. Error WMC 100." So I guess my question is what does this error code mean? And how do I fix this?
