I have just bought a new netbook and now it runs ARCH linux.
To connect to the internet I am using an Alcatel x220 USB 3G modem dongle and wvdial (with pywvdial) and here is wvdial.conf
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = USB Modem
ISDN = 0
Modem = /dev/gsmmodem
Baud = 460800
Phone = *99#
Username = cellcom
Password = cellcom
Stupid Mode = 1
Init3 = AT+CGDCONT=1,"IP","internetg"
Everything works fine except it's seems to be locked into 2G mode.
Before I installed linux I tried the modem on windows, there I changed the modem to 2G mode only ( I do crazy things sometimes...) and I think the configuration was saved on the modem it self.
I searched google and found a lot of information of how to connect but nothing about switching between 3G and 2G.
The best solution would be to connect the modem to a windows box and change it ( or check if I'm even right) but I don't have one.
