I set up a “3” E122 mobile dongle about 2 hours ago for someone… here’s what I did
Make SURE your dongle is PLUGGED IN to a USB slot
Clear the wvdial.conf file
sudo gedit /etc/wvdial.conf
clear the contents, and save… close gedit
still in the terminal:
and wait till it returns to a prompt (you should see it detecting the modem)
close the terminal, but ONLY after it returns to a prompt
Right-click the “Network Manager” icon by your system clock, select “Edit Connections”… select the “Mobile Broadband” tab… select “Add”… make sure your dongle is listed under “Create a connection for this mobile broadband device”… click forward… select “Britain (UK)”… click forward… select 3 as the provider… click forward… select “Internet” as your plan… click forward, then Apply.
In the window that pops up…
Connection name: 3 Internet 1 (or whatever you want to call it)
Mobile Broadband tab:
tick in: Connect automatically (if you want)
tick in: Available to all users (if you want)
ALL other boxes clear, except if you’ve set a PIN number for the dongles SIM
Authentication allowed methods should ONLY read PAP… so click the “Configure Methods” button, and remove all options except PAP.
Clear ticks from ALL OTHER BOXES on the PPP tab screen, except -
Connect automatically (if you want)
Available to all users (if you want)
“I” had to disable wireless, otherwise it would connect, but I was unable to browse the web… but this shouldn’t really be necessary.
Reboot with the dongle in… and as long as you ticked “Connect automatically” the internet should just work… if you didn’t select “Connect automatically” you will have to right click the “Network Manager” icon and select “Enable mobile broadband”
