Sometimes, my Novatel U760 aircard will shut itself off while plugged into its USB port, thus knocking me offline. The popup dialog box has a check box ticked to enable logging of these events.

My question is simply where can I find that log so I can see what's causing me to be knocked offline.

Thanks.

I have the u720 and it has been driving me crazy. Mine is plugged into a Kyocera KR1 router and the router keeps a log. When it cuts off the error in the log is "connection terminated by peer". I assume this means Verizon is throttling the connection. I don't think it has anything to do with you or your card because I have used many cards and configuration and this happens at least once a day. What is your transfer rate, per month? They told me mine was 14gb per month (and that was a light month) and the guy at the store indicated that was a lot, so it wouldn't surprise me if throttling is the culprit.

The only other wildcard I can think of is if you are on a fringe coverage area like me the signal dips out sometimes. I don't know about the card you have but the U720 has a dual band antenna that is worthless indoors. I get full bars on clear, sunny days, but if it's overcast or stormy I get three to zero bars.

Hope this helps, good luck!

I'm in a good area as far as coverage goes. I monitor my bandwidth (10 gb cap) and have never gone above 8 gb in a month. I'm not using an antenna, just the extension cable that came with the aircard.

Is your issue the same as mine where the aircard isn't just losing its Internet connection, but actually shutting itself off while plugged into the USB port (the hardware disconnected sound plays)?

Well the light goes from flashing to constant when it is disconnected but when I had a card plugged directly in the pc, yes, that exact thing happened.

That sucks. It's frustrating because the problem could be a defect in the card, the USB port, the BIOS, the motherboard, in your case, the router. It doesn't seem like there's a way to narrow it down to one root cause.

Well you can plug some thing else in the usb port and if that device works then we can eliminate the usb port that way. Also I have had issues with those card as well doing that, but I have never had it disconnect on me while it is plugged in I have had it drop signal and have stop dead for an hour for some reason.

I just read a thread about it on verizon's discussion board about this and they suggested getting a self powered usb hub to plug the card into to avoid this. I am going to give it a shot once I find one.

Hello I think that you should disable your other internet connections if you have any (Wi-Fi Ethernet) and did you notice if your battery is low because sometimes when your battery is low it starts to shut off devices. maybe you should try changing your power options to high performance.
