As the topic mentions, I have this problem. I use the normal "connect" option on the right hand top and I am able to successfully connect to the network using 12.04 but not using 13.10.
May I know why and if there is a solution?
Follow these simple steps.
From here: Hoovam:Ubuntu 13.10 Not detecting dongles
Step 1 : First thing first, plug in your dongle :)
Step 2 : Click the network indicator in your menu bar. You will see that Ubuntu 13.10 is not showing the 'Enable Mobile Broadband' option in the network indicator.
Step 3 : Open the 'Disks' application.
Step 4 : You will see some 'Disk Drivers' listed under 'Devices' list. Eject the 'CD Drive (dongle specific)'.
'CD Drive HUAWEI Mass Storage' in my case.
Step 5 : Within 1 minute, you will see the option 'Enable Mobile Broadband' in your network indicator. Go ahead and connect. Done.
Hope it will solve your problem.
