Region : Austria

Model : TL-MR3020

Hardware Version : V1

Firmware Version : newest one

ISP : Mobilkom A1

I have got my 3G Router 3 days ago and can not get it to work with Modem ZTE K3570-Z. I tried the newest FW Version and the previous one to no avail.

The modem is identified but will not connect.

The modem works on various notebooks with different SIM cards in different networks (Vodafone Turkey, Mobilkom Austria, Orange Austria, Yesss Austria) and countries.
So I suspect it is not the modem but the router. Although the modem is listed as compatible by TP-LINK.
A modem borrowed from a friend (ZTE MF 626) works on the 3G router with all the SIM cards I have.

The logfile below contains a message saying check APN and dial number. As my tests showed the dial number and APN are correct otherwise the borrowed modem would not work.

Here is an excerpt of the logfile:
