MBRN3000 Unable to connect broadband network

Hallo

I was using the MBRN3000 with ZTE MF652 3G USB stick. This one started to overheat and was disconnecting me from broadband.

So I got my self a stick which is on the list of netgear MBRN3000 support 3G modems the used ZTE MF112.

Used, because it is hard now to find the suitable stick which is supported by the router.

The stick works beautifully when pluged in PC, the connection is activated in 3 seconds.

But plugged into router stick is recognized by router, but the connection to broadband cannot be estabilished.

I tried various router revisions of firmware, even the newest one (MBRN3000-V1.0.0.74_2.0.12WW) but not succesfully.

The newest version is even sometimes not recognizing the stick.

Also tried to run the wizzard and setup the network newly, but also without success.

By recconecting old stick I get the connection immediately, but with the overheating issues.

What else could be the issue ?

Stick is unlocked to all networks, and in PC works perfect.

Thanks for any potential solutions
