Why does my device keep locking up?

Twice in the past 3 days, I have had to power-off reboot the MiFi Jetpack 6620L in order to be able to connect to the Jetpack Admin page.  Also, each time, network performance had degraded noticeably before I rebooted.  After rebooting, performance was back.

Have others encountered this?  I updated the firmware a couple of days ago, and it has happened twice since then.

Trying to figure out if I need to return and replace this one as a defective unit, or if there is some config/setting that would help.

I don't have great 4G LTE coverage (~90-96 dbm usually) and I wonder if the device gets lost hunting for signal?

kccrosser, we definitely want to make sure you are able to fully use your MiFi without any issues. Through your 6620L's screen, if you go to Settings>Network Technology> If you are currently Set to Global, try switching it to just LTE Only, and see if this makes a difference while at home.

Keep us posted!

If you have removed and reinstalled the battery and SIM card and the situation remains unchanged, I would contact Verizon Wireless Customer Service (800) 922-0204 for a replacement. I can’t think of any setting that would fix it.

Firmware update problems should be reported to VZW.  If they botched something they need to know about it directly.  Firmware problems are usually supported even outside of warranty dates.

I have made the change to LTE Only and will see if that solves the problem.  I had to reboot just an hour ago, so I hope this makes a difference.

Ok - after two weeks, I have not had to reboot the MiFi.  In addition to switching to LTE only, I also put the device in "stealth" mode, so it isn't flashing the blue light all the time.  I installed the new firmware upgrade yesterday and will monitor, but it looks like the MiFi is now working ok.

Thank you for the LTE Only suggestion.

Unfortunately, I may have spoke too soon.  The device locked up again and had to be rebooted this morning.

Interestingly, when I hit the power switch, the device screen came up with the confirmation page that the system update had completed - from the June 1 update that I did.  I clicked the "Ok" button and then turned it off and back on.

Recycling the device restored operation.

I will monitor it - if it continues to hang, I may ask to replace it with another or with the LTE router.

So I have a similar issue I think... I don't know if it is a "hang" but the Jetpack was powering off overnight and during the day when I had my Wemo and Canary connected to it. I adjusted the power management settings to never go to sleep or power off. I power cycled the device and thought we were good, but the wifi itself shut off last night and the Jetpack stayed on. I don't know if this is the "hang" that you speak of, but I could not connect to any device to it when we got up this morning even though it said it was on. Wordering if there is another setting I should have adjusted. I looked again this morning, but didn't see anything. It did both updates a while back too....
