[SWLUG] Ubuntu/KDE lost internet connectivity-KNetworkManager etc

Mon May 19 15:30:53 UTC 2008

I've tried googling your apparent compiling issue and from what I can find it seems pretty unique... You may wish to try filing a bug report to the ubuntu team. But I'm stumped, it seems quite bizarre.

Have you tried running Wireless Assistant from the command line, to see what errors that spits out? What kind of wireless card do you have?

Thanks for the interest.  I know the route/gateway and DNS settings but 
cannot set them as KNetworkManager's Manual configuration is not 
appearing.  I cannot connect to the Internet with CAT5 either.

Although I boot directly into a user, (version 2.6.24-16)I studied the 
grub boot loader and have many options
Ubuntu 8.04. Kernel 2.6.24-16-generic
Ubuntu 8.04. Kernel 2.6.24-16-generic (recovery mode)
Ubuntu 8.04. Kernel 2.6.24-14-generic
Ubuntu 8.04. Kernel 2.6.24-14-generic (recovery mode)
Ubuntu 8.04, memtest86+

I tried the third option: Ubuntu 8.04. Kernel 2.6.24-14-generic
The mouse did not work and I got a loud  feedback type noise over the 
speakers that I could not turn off.

So next I tried: Ubuntu 8.04. Kernel 2.6.24-16-generic (recovery mode)
This booted to a memu with three options: resume normal boot, Drop to 
shell prompt, try to fix X server.  I was not sure what to do so I 
resumed normal boot.

Next was: Ubuntu 8.04. Kernel 2.6.24-14-generic (recovery mode)
This booted to a memu with three options: resume normal boot, Drop to 
shell prompt, try to fix X server.  I was not sure what to do so I 
resumed normal boot, and got the same feedback noise again

On screen the message says something about not being able to compile 
with gcc.  I went looking for this package but it was not installed and 
not available either.

At a loss and hoping there is something to be done

Thanks
