PPP chat scrip failed with 4G Sierra modem



  • Hi,

    Before March 6th, my APU2 from PC Engines with a Sierra MC7710 modem 4G was working perfectly.
    I did the last 2.3 Beta update, reboot and no more internet with the Sierra MC7710 !

    What did you change ? ppp update ?

    Thanks in advance.

    Regards

    Nicolas

  • Nothing related to PPP has changed in our code in quite some time. Doesn't look like there have been any relevant FreeBSD changes in quite some time either.

    There is nothing answering your dialing attempts. I suspect the card itself stopped connecting to the cell network after the reboot and it was unrelated to the upgrade. If you power cycle the box so the modem gets reset, does it still fail the same?



  • Hi,

    Apply latest 2.3 Beta, problem fixed !
    Maybe the card itself hangs, i don't know really what's happen.

    Thanks.
