Root command line access for MPR-L8 / A5-V11 mini 3G routers


These small routers have a built in telnet service, which can be reached by telneting to the router with your favorite telnet client (e.g. Putty). The user name is admin and if you have not changed the password it is also admin.



After logging in you will have a BOC router> prompt, and a very limited set of commands available.

Here if you enter the command "runshellcmd" you will get a full functional linux shell.


A now you can do all funny things like:

  1. backup your firmware (cp /dev/mtdx /mnt/sda/xxx) to a plugged in pendrive
  2. fix modem recognition problems with usb_modeswitch
  3. change all settings with nvram
  4. flash a new firmware with mtdwrite or simply copying the new firmware to /dev/mtd3

Thanks. I'm wondering if the USB is stable on here? I want to put OpenWRT on it and connect it to the wired LAN on my router to use as an FTP server

The whole thing is not very stable, but the USB is not less relaible than the rest of the router. So I propose that you experiment with it.

Im my blog you will find some instructions on how to install OpenWRT on it.

Setting ethernet interface speed in /etc/network/interfaces

There is an easy way to set the network interface speed in Ubuntu 14.04: In the iface section of the /etc/network/interfaces  you can add the link-speed and link-duplex parameters, to pass them to ethtool. The example below sets the link speed to 100 Mbit/sec: iface eth1 inet static         address 192.168.1.120         netmask 255.255.255.0         network 192.168.1.0         link-speed 100         link-duplex full
