I just bought the 3G Modem TP-Link MA180 and I try to install it on Ubuntu 12.10.
Problem : Network Manager does not detect it. I saw on the web that
usb-modeswith is supposed to handle it, but I don't know how to configure it.
try my solution on my blog! http://fcastagnotto.wordpress.com/2013/04/29/usb_modeswitch-ubuntu-systems/
I use a Ubuntu 12.04.2 LTS i686
