network problems after zypper up to latest factory

I did an update yesterday and all seem to go fine, then I noticed that I couldn’t get out on the network. Upon closer inspection, it appears that I can send packets and not receive any back. This was a working connection up until I rebooted after doing the update. Has anyone experienced a similar problem? I’ve tried rebuilding the kernel to no avail, same problem. Is there a setting somewhere that needs to be tweaked to fix this?
Any ideas/help appreciated.

Sorry, forgot to include version info, my version is 11.5 M0, uname -a gives x86_64

Had the same problem and rolled back NetworkManager and NetworkManager-Glib packages to the 11.4 versions to resolve the problem.
