Wireless connection shows connected, but doesn't work

I guess the title about says it all.

The network manager say that there is a connection and the lights on the card are on, but whenever I tried to load a web page or install a package through Yast I get a no connection error.

I can reboot the computer and everything works for a few minutes then quits.

At first I thought it might be the router, but my computer works normally, (problem is with my daughter’s)

I’m wondering if her wireless card is going bad.

Her machine is running openSUSE 11.2 with KDE 4.3

Any help is appreciated

We need any output that might be in the logs. Enter the command ‘dmesg’
and look at the stuff near the end after the connection drops. As you
didn’t even tell us what kind of device it is, we have to be mind readers.

Am I correct in assuming that networking does work a couple of minutes after reboot, incl. internet usage, then stops working?

Yes, The connection works briefly after startup, then is gone. However, Network manager shows that there is a working connection.

I’m currently trying to install vlc media player for her. As soon as the connection give out I’ll post the requested info from ‘dmesg’

I’m using a Broadcom pcmcia card. I don’t remember the exact model number but it uses the b43 firmware. (when connection stalls I’ll pop the card out and look if you need that info)

Here is my ‘dmesg’ output. Hope there is some useful info in there. It’s all greek to me. Also, today Network manager shows no connection and attempt to reconnect fail, but both lights on the card are on showing that it has power and is receiving a signal.

The previous set of messages were all packet drops by the firewall. Is
there a message about deauthentication?

You might have better results with the compat-wireless package for your
kernel.

If your’re using NetworkManager it’s may even better to see the /var/log/NetworkManager log.

Hy

When your internet connection is down, try ifconfig to verify if the network card is still active and has a ip address, if you have an ip address try to ping the gateway to verify the connection between the network adapter and the router.If you receive icmp from the router it may be a problem at your ISP, witch connection does your isp use? static IP, pppoe, dynamic ip?? Try also to view the router log.

Awaiting your reply.:wink:

thanks for the replies. My internet connection is down due to a power outage. I will post the network manager logs as soon as I can.

Many thanks to everyone who tried to help me.

For now everything seems to be working properly. I can’t seem to get the connection to drop this evening. Perhaps the problem was with my ISP and was fixed while things were down this morning.

If it happens again I suppose I will have to start a new thread at a later date.

Thanks again.
