huawei e303 stick on mikrotik routerboard

hi

To get the stick running with mikrotik routeros it’s mode has to be changed to serial modem.
I do this with my ubuntu 14.04 workstation.

First install usb-modeswitch and minicom:

aptitude install minicom usb-modeswitch

Now plug in your stick configure the ip-address of the usb network interface. We also have to set the ProjectMode via http request.

ifconfig ethx 192.168.1.2 netmask 255.255.255.0
http://192.168.1.1/html/switchProjectMode.html

Afterwords fireup minicom and change modem to modem mode (turn off hardware flow control)

minicom -D /dev/ttyUSBx

Paste the following code to minicom terminal

AT^U2DIAG=0

When you plug in the stick to the routerboard now you get an pppx dialer interface.

Have fun!
