Issue with internet speed dropping. If I reset it, the speed comes back for a few hours, but then drops off again

Hello again, Thought I would try the forum once more. Anyone have any ideas? Not sure, maybe Im not meeting forum requirements, but I have been trying to get some help here for a month.

Hello, Please help. I have a Pepwave MAX BR1 MK2. The internet will work fine. Uploads about 10mbs and downloads about 70mbs. Then the speed will drop off. If I unplug it and plug it back in it will come back on with speed. But then drops off again, usually after a couple of hours or so. Any help would be great. I have noticed the cellular indicator light will turn off. And then I reset it and it reconnects.

Thank you, Jesse
