I have installed a fresh copy of ubuntu 12.10 64-bit on samsung laptop (Model np350v5c-s0bae). The only problem I face is how to make the USB modem stick (Egypt Etisalat - ZTE MF190S) working.
This is the output of
Bus 003 Device 007: ID 19d2:2000 ZTE WCDMA Technologies MSM MF627/MF628/MF628+/MF636+ HSDPA/HSUPA
I have tried the stick modem on other machines and it is working properly.
