broadband

The problem is, I have used Ubuntu from 6.10 upto 11.10. And upto 11.04 I used my same USB 3G dongle to connect to broadband and it worked fine. But 2 days ago I upgraded to Ubuntu 11.10 and broadband is not working. It detects my dongle and creates a connection without a problem, but when connecting it just keeps on and on for a long time and then say I'm offline. So I did a clean install and the same thing occurred.

But I also have a netbook and its got Ubuntu 11.10. I tried using the same dongle for internet on that netbook and it worked fine without any issues. But this isn't a problem with my USB port on my main machine or something like that because I'm also using Windows on my main machine (dual-boot) and its working fine.

My hardware:

Main computer (one that I'm trying to connect):
- 2.8GHz dual core Intel
- 2GB RAM
- 500GB Sata II HDD
- 384MB Video Memory (Intel G31/G33 chipset)
- Ubuntu 11.10 (32bit)
My NetBook (broadband working fine):
- 1.6GHz Intel Atom (dual core)
- 1GB DDR3 RAM
- 250GB HDD
- 128MB Video Memory (Intel something-I-can't-remember)
- Ubuntu 11.10 (32bit)

My dongle is a Huawei E220 and ISP is Dialog GSM (I'm in Sri Lanka)

So any idea why this is? I really love Ubuntu and this is bugging me off.. Any help greatly appreciated.

Regards, Roshnal
