Posted: 19 Sep 2022, 18:08
Hi, I have USB GSM modem ZTE HSPA+ Turkcell VINN MF667, whose vendor-product ids : 19d2:1405. While I can connect, it fails. I replug the modem, go to its internet browser router interface from 192.168.0.1 and interface is working. Green light is blinking. After entering PIN, it goes Connect menu. However, when I pressed "Connect" button nothing happens, it is not connecting. I tried :
