Hi all! I have in the past, rarely, had the "thunderbolt can't get a signal" disconnects that many have had. Recently, (within last two weeks), I have a new issue. I can't get the TB to stay connected to the PC. For hotspot, I turn hotspot on, it connects, everything is great. Often (6 times an hour now?) the wireless connection drops, and when I look at the phone ... phone says 4g signal strength fine, can browse internet on phone fine, BUT, hotspot shows 0 connected users. Turn hotspot off, turn hotspot on, computer wireless connects, internet on PC works fine for awhile, THEN DROPS, hotspot says no connected users, rinse and repeat. The thunderbolt seems to have 4g connection just fine the whole time, but, hotspot won't keep my PC connected. Related issue .... I figured I'd try a USB cable, in case there was some wierd wireless issue .. but ... I connect the USB cable to PC, it starts to charge so I know they're connected but .. when I click on internet connection, it gives me a message that says "connect USB to computer" ..... /sigh Anyone got any help to get PC internet back up and stable through the thunderbolt? Thanks!
