Not sure why this keeps happening. Sometimes drops, but mostly freezes and says "connection dormant". I researched another carriers wireless USB modems, and i'm ready to switch. 1) they cheaper 2) their overages is 5cents per MB, vs. $10 per 1 byte over with Verizon. 2) Their equipment can't be worse. Already got new modem once. Done firmware updates, uninstalls, reinstalls, etc. Takes about 100 of my talk minutes onmy cell phone to do another fix...and back to same "freeze" problem, where modem will say "connected...dormant" DOes NOT just happen in one PC. Tried in another, and did same thing there. You then "wait 2-3 minutes..opening new IE windows, hoping to "jump start" the darn modem.
It's "annoying" and I get "disconnected" from what I'm doing. Upgrading to 4G was worst decision ever. Will this ever be fixed? Looks like no other options with Verizon as far as modems. I'm ready to keep paying for nothing till "dec" when it can supposedly cancel (I've had Modems for like 4-5 years) and switch immediately to the other Carrier. Because no other modems will be avail in December. I dont have routers or antennas or whatever everyone else is discussing here on "discussion"...just the USB modem.
(However, going to try the "mobile hotspot" from the other carrier.)
