Model : TL-MR3220

Hardware Version : V2

Firmware Version : 3.13.27 Build 120905 Rel.73281n

ISP : Tele2

So i have this problem here.

Firstly I have exactly identical setup working at my grandparents house all good with that.

But the problem is that when i connect the 3272 huawei modem to my MR3420 v2 it recognises the modem, gets the signal at about 80%, and further connecting starts recieving and sending packets, sends and recieves both 4 packets(36 bytes recieved, 70 bytes sent), then it disconnects the modem and the whole process starts all over. It has been running for a nice 20minutes already and i cant figure out what is the problem.

No password on the modem.

I have tried changing the APN, but no hope.

Resetting the router several times and also factory default reboot once.

The modem does work well when connected to PC and the internet provider told that it cannot be their problem aswell.

Any help is welcome.
