I have received this unit GL-E750V2 2 days and everything seemed to be working until this evening.
Every 20 MIN it disconnected
No internet! and I have to reboot.
I continued on with the troubleshooting and 1st I replaced the sim card and the issue persisted.
I finally went ahead and restored the firmware u-boot and the unit has now been connected without a drop for the last 7 Hours.
I think the unit is fragile any changes that is made on the network portion causes the modem to disconnect and I think I did something wrong.
For now it is working.

And it disconnected again, but for a few minutes:
Can someone tell me why it is still disconnecting

And now it is now again disconnecting... There is nothing more I can do as there are several posts that have the same symptoms and have gone unanswered.
Returning the unit!
