Hi. Had a working PPP communication over PPP, but after upgrade from 2.23 to 2.27 it stopped working. Tried tp roll back to old fw, but still not working. Any suggestions on what could be wrong. Have checked baudrate etc . Are using a logger in the other end.
Hi,
Have you resolved the issue? Please try to check if modem still registers to mobile network.
Did you get IP address when you are dialing ppp?
If so, you should to build your routing source to ppp0 interface.
