Modem unreliable on the PPP with Mobian
#1
I am using my Pinephone Pro EE since monday as a daily driver. Works good so far but since yesterday the modem began having hiccups.
Sometimes it shows no reception or the bar symbol is crossed out completely.
With mmcli I can see the modem in the first case but in the second it is not found.
I tried various combinations of mmcli scan and disable/enable with no result. Only restarting the phone works most of the time.
However when I restart the phone some settings (display zoom, input voltage from keyboard etc.) are gone.

Is there a reliable way to use modem manager to restore the connection?

What modem firmware are you running? Biktorg version with advised parameters works fine for me.
  • ROCKPro64 v2.1 2GB, 16Gb eMMC for rootfs, SX8200Pro 512GB NVMe for /home, HDMI video & sound, Bluetooth keyboard & mouse. Arch (5.19 kernel, Openbox desktop) for general purpose daily PC.
  • PinePhone Pro Explorer Edition daily driver, Tow-boot on SPI, Arch/phosh on eMMC
  • PinePhone BraveHeart now v1.2b 3/32Gb, Tow-boot with Arch/Phosh on eMMC
