Thanks for the custom firmware, it's made getting started with Openwrt on this router modem very easy.

I'm having an issue with the cellular connection dropping every couple of hours, then it won't connect until I manually restart wwan0 (or reboot the router).

Is their a way for the modem to do this automatically?

Hi,
Try to set a connection monitor for the interface on which the modem is working. OpenWrt is not always able to reconnect, sometimes it needs help (using additional packages or scripts).

I found within the pages of the OpenWrt Wiki a way to pass commands to the modem in uci using the package uqmi, with options not available through Luci.

uqmi --device=/dev/cdc-wdm0 --autoconnect
uqmi --device=/dev/cdc-wdm0 --set-autoconnect enabled

Not sure if it will have the desired effect, but I should know by the morning.

Please accept my apologies, I completely ignored your directions to "Connection Monitor" under "Services" which I've just set up.

Hopefully this will help.
