How to enter AT commands for a 3G modem on Zyxel Keenetic?

Question

network hardware

Here's a problem for you. There is a pop home Zyxel Keenetik router. A 3G modem is plugged into it (e3272, Megafon, but it doesn't really make sense). How can I send an AT information command to a modem connected to a router ?
For example, I want to know the version of the modem:

(config)> interface UsbLte0 modem init 1 ATI
Network::Interface::Repository error[6553607]: unable to find Network::Interface::UsbModem container.

I understand that you can see exactly this in the web interface. But there you can't see, for example, the type of the current connection (edge, 3g or lte), you can't find out the current balance, you can't ... and a lot of things that you can get with the AT command.

Answer 1

Most likely in any way, the native CLI is greatly curtailed. If you really need to send AT commands, then flash openwrt

Answer 2

No way. Sokhovsky iron - for those who are without requests, it is contraindicated for people with a head. Only a patch.
