Hi Guys,

I have a LB2120 and it is working fairly well.

I'm in a regional area and have it connected to an external 4G antenna.

It's permanently connected to 4G it isn't not used in fail over mode.

When I first boot the device it shows 5 signal bars on the modem and it goes like a rocket.

Ping 39ms 53Mbps Down and 28Mbps Up.  

After around 30 minutes it drops back to 2 signal bars and and stays that way indefinately

The speed is considerably slower especially the upload speed.

Ping 39ms 29Mbps Down and 2.85Mbps Up.

This is very consistant.  It does it every time I reboot.

Does anyone know what is going on here?
