Netowrk not working after networkmanager update [Solved]

[tohi99]

After working perfectly since installing 6 months ago, recent updates have caused a number of network problems.
When setting up initially I had it configured to start the wirless network before KDE started, After a recent update I now have to enter my password into KDE wallet to get the wireless network to connect. If I'm not quick enough I end up with a KDE crash handler dialog.

After the last networkmanager update yesterday, the wireless network will not connect at all.
I have tried to connect via a network cable but it is not working either.
Having to post this from another computer on the network, running Sabayon 8 KDE also, but a few updates behind.
Looking at the log file, it would appear (for eth0 anyway) that the problem may be associated with IPV6, as it is getting an IPV4 address from the router but failing when trying IPV6 which I don't use.
How can I stop it trying to use IPV6?

does blacklisting ipv6 work?

sudo echo "blacklist-ipv6" >> /etc/modprobe.d/blacklist

[LCN_UsesSabayon]

I noticed same issue.
In order to isolate its root source, Yersterday I decided to performed a minimal fresh installation (CoredCDX 8 Amd64 + GDM + GNOME-CORE-APPS)
After installation finished (networkmanager 0.9.2) I can connect to my home network using WPA2 (My ISP and my router provide both IP4 and IP6 addresses) without any issue.
Then I performed equo update / equo upgrade --ask => New version of NetworkManager is suggested (0.9.4)
After upgrade was performed and computer was rebooted, I cannot connect
I don't know if blacklisting IP6 could be useful since both IP4 and IP6 are managed in my case but I will try this trick when I'm back to home

[ratcheer]

Hmmm. I could not connect after last week's update, but after this week's, I can connect again.

Stopping ipv6 loading did not help and even with it not loaded there is still messages about IPv6

Also uninstalled avahi in case it was causing an issue, but still not working.
Interestingly the file /usr/libexec/nm-dhcp-client.action eth0, shown above being passed to dhcpcd, is one of the files which was changed/updated as part of the update after which things stopped working. Don't know what it does or if it is relevant.
I have managed to get a wired network connection working by manual configuartion of eth0 interface.
I can't get wireless working at all. Seems the fix for other peoples wireless problems has broken mine.

I will keep investigating myself, but any suggestions would be greatly apprectiated

Same here...

Yesterday evening, I installed Sabayon again from scratch (see my previous post).
At upgrade step, there were 18 packages to be updated (only 2 on last tuesday attempt)

Now NetworkManager works well for me

@Toihi99:
This may be a mirror issue.
You can try to reinstall networkmanager (equo update --force + equo install networkmanager --deep)

[tohi99]

after doing the equo update --force, the upgrade for KDE 4.8.3 appeared.
Upgrade run and networking seems to be working fine again (but have a few issues with Firfox 12.0 though)
