Alix6b2 + Novatel EU870

Hi all!

We test RouterOS v3.15 on Alix6b2 + EU870 3G modem. It seems the system works fine until some moment when the system makes reboot and after this the modem doesn’t connect to the internet (to provider). The status of the PPP connection is authenticated, but not connected. The only possibility to solve the problem is to turn the power off and in some time to turn on.
Enable/disable of the PPP-client doesn’t help.

Maybe someone had the same issue with Alix6b2/EU870? Any suggestions?

Thanks in advance.
Regards,
Vadim
