I recently upgraded my Verizon 7730L jetpack to the Verizon mifi 8800L jetpack. I've been a little reluctant to do so because it has such bad reviews on the Verizon website. A few months ago the reviews were great. Recent reviews are terrible though. They all talk about how the device randomly drops connections. Well, my 7730 was doing that too. Pretty annoying, but it sounded like the 8800 was even worse. I did some research and came across this youtube video: https://www.youtube.com/watch?v=oCRjj6lT1cA. It talks about how there is a setting called Sleep Mode. The default value is 5 minutes. I took a look at my 7730 and sure enough it also has a sleep setting and it was set to 5 minutes. What this setting does is put the device in sleep mode if there is no internet activity after whatever the sleep mode is set to. If the setting is set to 5 minutes and you walk away to go get a snack and are gone for at least 5 minutes, when you come back, the connection will be dropped. I keep my jetpack plugged in all the time, so I think this setting is relevant when running only on battery in order to conserve battery power.
I changed the sleep setting to never on my 7730 and have not had any issues since. With this great result, I took a chance and upgraded to the 8800. Sure enough, the sleep setting was set to the default of 5 minutes. I immediately changed it to never and it has worked great. The 8800 is actually a pretty big improvement over the 7730. My son's Fortnite ping has dropped from 60 - 70 to 30, which is good. The lower the ping, the less lagging.
