Actually, the problem of Q101 is that Q101 will not turn GSM modem to full function properly while plug-in.
Therefore, you will need to turn it on manually.

The way to turn it on the writing "AT+CFUN=1" to the /dev/ttyUSB2, after q101 switch to modem mode.

You can use minicom, cu, tickminicom, or screen to do that. You can choose whatever tool you want to use. :)

if you want to use tickminicom.
you can do as following:
> git clone git://gitorious.org/tickminicom/mainline.git tickminicom
> cd tickminicom;make;sudo cp tickminicom /usr/local/bin/tickminicom_x86


Note:
1. You will need to add q101 swtting to the usb_modeswitch.conf

>diff usb_modeswitch.conf /etc/usb_modeswitch.conf

2. wvdial.conf need to be setup properly. (see former posts)

>cat /etc/wvdial.conf
[Dialer Defaults]
Phone = *99#
Username = username
Password = passwd
Stupid Mode = 1
Dial Command = ATDT
Check Def Route = on
Dial Attempts = 3
Modem = /dev/ttyUSB0
Baud = 460800
Init1 = ATZ
Init2 = ATE0V1&D2&C1S0=0
Init3 = ATQ0 V1 E0 S0=0 &C1 &D2 +FCLASS=0
Init4 = AT+CGDCONT=1, "IP","Internet"
ISDN = 0
Modem Type = Analog Modem
New PPPD = yes



This way I can get the network without many troubles. The only issue is that I may not get DNS prperly, but I think it's a issue from ISP service. You can Ctrl+c and run again. normally, it will work well within two runs.
