This post is for anyone having problems getting the O2-provided Huawei E169 USB modem to work under Linux. I’ll assumed you’ve searched elsewhere and have an idea of what is going on.
In my case, I had a Gentoo GNU/Linux desktop without internet access although I did have a Windows XP laptop to help me. The best thing to do is use the USB modem on the laptop, connect up your desktop by ethernet cable and share the Dial-up connection in order to download any packages you may need.
gentoo-sources-2.6.28 is a good enough kernel to get things to work.
emerge usbutils ppp wvdial
sudo make menuconfig

sudo make -j 3
sudo make modules_install
(Which installs the kernel modules. Restart computer.)

sudo rmmod usb-storage
just in case.
sudo modprobe usbserial vendor=0×12d1 product=0×1001
/dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2
if only /dev/ttyUSB0 is shown, then unload modules ‘usbserial’ and ‘option’, unplug device and try again from the marker (**).
to get a template /etc/wvdial.conf for editing. Refer to https://help.ubuntu.com/community/DialupModemHowto/Huawei/E220/wvdial.conf and other websites to aid configuration.
APN (Access Point Name) mobile.o2.co.uk
Phone number should be *99***1# otherwise try *99#
When you have your /etc/wvdial.conf set up properly, connect with
One section I have is
[Dialer internet] Init5 = AT+CGDCONT=1,"IP","mobile.o2.co.uk" Stupid Mode = 1
Carrier Check = no
in your defaults if you get no carrier errors.
