AirCard AC875 won't work with Ubuntu 9.04

Asked by JohnL on 2009-07-02

After installing Ubuntu 9.04 and running the network connections setup "wizard", connection fails.

Log file shows that the hardware is recognised and appears to install - see below

Installing the old GSM and GSMchat files that worked fine in Ubuntu 8.10 doesn't work either - typing

pppd call GSM

which would start up the modem in 8.10 gives error as shown below

   john@john-laptop:~$ sudo pppd call GSM
   Connection script for Sierra Wireless GSM/UMTS...

   Script /usr/sbin/chat -v -t3 -f /etc/ppp/peers/GSMchat finished (pid 4669), status = 0x3
   Connect script failed

The GSM and GSMchat files which worked in Ubuntu 8.10 are shown below. The only specific values appear to be Telstra.datapack and the dialup number *99# which the Ubuntu 9.04 wizard seems to have correctly interpreted (the "Network Connections" dialog displays these values.

Can anyone help with getting an Aircard 875 installed and working with Telstra under Ubuntu 9.10 ?

Hi,

You might want to have a look at bug #371291 and the comments therein. It is about a slightly different model (AC880) thought.

Hope this helps!

Thanks Arnaudus, that solved my question.
