Please help me trouble shoot this problem. I am new to Ubuntu and am not sure where to turn. I will post as much info as I can, it may not all be relevant.

My system will start up and connect to the wireless router, but after some time (variable 1 min to 45 min) it quits working and won't re-connect.

Any idea? I will include all of the output code I can

~Bump~

Anyone? Dell customer support is horrible. I sat on the phone for two hours yesterday only to be told that no was working who was familiar with Ubuntu. I could really use some guidance.

Thanks,

Hi there

Iḿ having a similiar problem on my desktop. After restart the wireless network is running for random time (often 2-8hours) then it looses network connection. I cannot ping anything. If I do :
sudo /etc/init.d/networking restart
then Iḿ able to ping the router and useually nothing else (once I was able to ping outside of my local network).

I have tried
sudo /etc/init.d/dbus restart
but it did not seem to affect anything.

If I try iwconfig I can see that I have IP adresses and everything looks the same as when the network is working properly.

Iḿ running 2 wireless cards on my computer (actually running as a server). Before updating to 8.10 everything worked flawlessly.

Regards

My issue does happen with all wifi networks I have connected to. Two with WEP and two without any securtity.

I don't get an error, other than what I posted in the system logs, I just loose connection.

Hi

Im not getting any error message.
-The browser is not connecting.
-Apache is not accessible
-Samba is not accessible - ie shared folders are not accessible
-Its not possible to ping or connect to the server on IP. The only way to access it is through the virtual server on the router - ie my internet adress is working.
-If I restart the server or restart the network service in ubuntu everything works for a while - then it stops working again.
