[SOLVED] Network Manager problem after upgrade to 8.10

[susyp]

I have no network conection after upgrade to 8.10. With live CD ubuntu 8.04 it works.
I downloded and installed the most recent network-manager and network-manager-gnome but pointless.
I've found in a post that /etc/NetworkManager/nm-system-settings.conf should be changed. In [ifupdown] managed=true. It is pointless too.
I've tried to downgrade. Downloaded tar-file of network-manager-0.6.5. After untar I run configure and got an error of "wireless-tools >= 28pre9 not installed or not functional". Well, I have no wireless card... .
Any help pleace!

I wouldn't worry about the version of Network Manager...there weren't any regressions breaking cards there that I've heard of. What I have heard of however is issues with the various changes to drivers.

What card are you using? Broadcom cards need to have firmware downloaded and there have been many shifts in the kernel with regards to wifi drivers between releases which should make things better in the future. If you can post the output of these commands that should help

lspci
lsusb
iwconfig
ifconfig
lsmod

Some of that output might be quite long so if you can, put it into some [ code ] tags

Hi!
Once more: I have no wireless card at all .
And I'm sitting behind a router.

Hi everybody!
I've found the solution.
The reason was the bugy maintenance of MCP55 nVidia ethernet. More details can be fond at https://bugs.launchpad.net/ubuntu/+s...ux/+bug/136836 .

In short:
you have to append to

/etc/modprobe.d/options

the next line

options forcedeth msi=0 msix=0
