Just switched this service from 3G with UMW190 to 4G and UML290 and I'm constantly getting a dropped connection/device connection. One machine an XP desktop, another a Win7 laptop. Drops network connection, even device connection, wait minute and the device and network come back and reconnect. I have not locked it in one mode or another, and frankly I shouldn't have to. I was just going to post this thread to add visiblity to what is quickly becoming an apparent problem with the Verizon service. But after dropping the connection 6 #$%#@$ TIMES just trying to register for this forum it's clear I need to contact CS and get my money back until this problem is resolved.
