View 4G modem signal strength & connection type

Technical Support for Routers
1

I have a Huawei e3372 modem connected to AR-300m router. I recently followed a guide to put it into “stick” mode, DATAPUISTOKEMISTI: Convert Huawei E3372h-153 from HiLink/router-mode to Stick/modem-mode [ UPDATED 2016-09-02 ]. It appears to work better, but no longer has its own interface which did display some useful info.

Is there a way to view signal strench of the e3372, and also the connection mode (4G, 3G, HSDPA etc)? Ideally through Openwrt interface.

great, this is exactly what I needed. I had to reboot the router and for it to start running, and then run the command to change the language. Thanks.

maybe I replied too soon: for a moment I did get data through, but now the status is always: disconnected.
here is the output of 3ginfo test:

I’ve tried reinstalling, and rebooting the rooter again, but still the same.

3ginfo.@3ginfo[0].network='wan’

Use proper network section here.

ok, thanks.

uci set 3ginfo.@3ginfo[0].network=modem
uci commit

worked.

It is connected now, but no details show, apart from received/tansmit.

Finally solved this as the modem was attached to /dev/tty/USB0

thank you.
