Configure Sierra Compass 885


I have a 3G modem (Sierra Compass 885). When I attached it on my openSuse 11.2, the Network Manager has deteced it. After that, using Network Manager, I configure the connection by filling the Dial number, Username, Password, and IPN. When I click OK the connection status always says “Waiting for authorization” and never connected.
Do you have any suggestion? :\ Any help will be very appreciated.


I had use of a Sierra Compass device up until recently, and used it successfully with kinternet dialling utility. You should be able to do the same with that, or wvdial if you prefer.

I remember messing with the hal fdi files, so that the device would be recognised by Network Manager, but it had the same symptoms as you described while trying to connect, so I gave up and treated it as high-speed modem instead. (That was with openSUSE 11).

Do you mean that the problem is Network Manager? :\ If that so I will try to use kinternet or wvdial as you suggested.

Yes, I think Network Manager may be the problem. It doesn’t always handle the latest wireless devices well. Each version gets better though. Using kinternet is a good way to start.

Make sure that you can see /dev/ttyUSB0 or similar when your device is plugged in:

ls /dev/ttyUSB*

Then configure with yast modem utility. You may need to install the dialler via yast software manager if not already installed.

This thread may be helpful to you.

Nice information. I will try it first.

Hey thanks a lot. My modem is working now. It’s detected as /dev/ttyUSB3 when I do wvdialconf command. After that I configure it with YaST modem utility as you told.

After the configuration is done I use KInternet to connect to internet. And it works. But before that, I have added the DNS IP of my provider in /etc/sysconfig/network/config file.

In this line, I add my DNS IP separated with space.

NETCONFIG_DNS_STATIC_SERVERS="*dns_ip_address_1 dns_ip_address_2*"

Good work. That last bit about adding a static DNS may be useful to others experiencing DNS issues with their wireless devices.

Make sure you pass your new found knowledge on to others where you can. :wink:
