I got a RUT850, I can connect to the router, status said sim card is okay, I got an exernal IP but no internet-access. I can not ping external IP-adresses like 8.8.8.8 I only did a basic setting. The former asked questions with same problem didn't help. Fimware update was done. Reset was done. PIN of sim-card ist correct. Tried with APN and wihout. Who can help? Thanks in adcance.
