Sierra aircard 880U wireless card (3G) not working
 

Hi, I'm fairly ignorant with regards to networking, and I've been struggling to connect to the telstra bigpond network in Australia via their wireless service for the last few weeks.

When I first got the modem, the data light flashed as expected (slow flashing if their was no signal, on when there was). The modules to go with the modem were included with the stock 2.6.24 kernel (which is what I'm using). I'm order to connect to bigpond I had to use a Windows computer to create an account (Telstra didn't provide any other way) This worked OK but ever since the data light on the modem has remained off (except for a brief flash when I plug it in) and I have been unable to establish a connection with my linux machine. Does anyone know anything about this?

Your probably going to have to get extra info from Telstra. Since it's a modem you'll need a phone number to dial, a username to use, password to use... etc etc etc... And yes I realize it's a 3g cellular? modem. Still needs all that though to work.

Solved
 

Thanks for the reply. Turned out that the problem was as simple as the carm being in low power mode (The bigpond software must have done this when I used it with the windows computer) Using the command at at+cfun=1 in minicom got the modem going again.

Is there a way I can mark this thread as solved?
