Modem gets disabled on every suspend

[xavi92]

Unfortunately, this is a well-known issue that has not been fixed yet. To mitigate this, I run the following shell script as a systemd service with root privileges:

Code:

#! /bin/sh

is_modem_available()
{
        if [ -z "$(lsusb | grep "2c7c:0125")" ]; then
                return 1
        fi

        return 0
}

is_data_available()
{
        if ! nmcli c show --active | grep -e internet -e gsm > /dev/null; then
                return 1
        fi

        return 0
}

TRY=0
while :; do
        if ! is_modem_available ; then
                TRY=$((TRY + 1))
                echo $(date) Restarting modem, $TRY try
                systemctl restart eg25-manager
                systemd-inhibit --what=sleep --why="Modem reset" sleep 60
        elif [ $TRY -ne 0 ]; then
                echo $(date): Modem restarted successfully
                TRY=0
        elif ! is_data_available; then
                echo $(date): Restarting mobile data
                systemd-inhibit --what=sleep --why="Restart mobile data" sleep 5
                nmcli c up internet
        fi

        sleep 5
done

This will restart the eg25-manager service if the modem disappears, as well as restarting mobile data connection if it drops. The latter issue seems to occur often during calls (at least, on my OG PP).

Remember to replace "internet" with whatever name is used by your APN.

I hope you find this useful!
