I’ve been helping a friend at work get Linux on her laptop. I installed Ubuntu Jaunty Jackalope 9.04 as this is quite good for new users (and we have a mirror at work). She connects to the Internet like many people these days, using a USB 3G modem. Her provider is Dodo, which actually uses the Optus network.
Anyway, I was pleasantly surprised when I plugged in the device and Network Manager popped up a wizard prompting for a new connection. Yep, the device just works on Linux.
Unfortunately there is no “Dodo” profile the Network Manager, but knowing it runs on Optus network I chose “Optus 3G”. I booted into Windows to get the APN, as it will be different to Optus. After changing that I just needed to click on the Network Manager applet and tell it to connect. But it didn’t work. It tried to log on, everything goes green and then BAM. Nothing.
There was obviously something else that was needed. I checked the settings and saw that the Optus profile had DNS servers hard coded. I grabbed the DNS servers that dodo uses and put them in instead. This time everything worked and I could log on. Internet, she was a working.
So, for anyone already with Dodo or thinking about it, here are the settings I used.
APN: dodolns1 (that's a letter "L")
DNS: 18.104.22.168, 22.214.171.124
You will need to register your account with Dodo first and activate it. After that, your Internet should work just fine by using these settings.
It seems that it’s often quite slow when compared to Windows, which I’m putting this down to the Linux driver. Speeds seem to range between 600b/sec and 50kb/sec, which is a little disappointing. It could just be signal or something else, I’m not sure. Still, it’s great that it works out of the box under Linux. Now if only I could get Mike’s friend’s Telstra stick to do the same! HAL rules here I come..
