Network Disconnected 12.3 (After possible update?)

I haven’t booted my desktop computer for some time, and when I booted it up today my network manager is dead and extremely buggy. I have no idea what caused this failure. I do indeed have a network connection, because I am sitting here typing this using #! on my netbook. I have read a few other threads that have a number of suggested avenues to take in such an event…such as switch out for an earlier kernel version, restart the network manager services, and so on. I have had no luck with the network manager and can’t seem to find how to default to an earlier kernel version.

Can someone help me revert to a different kernel version somehow? I saw a post that mentioned the advanced tab on the grub2 splash screen, but I don’t see any other kernel versions available. I am beginning to wish I had stayed at 12.1 where at least my boot times were reasonable, I had a stable connection, and I had no graphics driver issues.

I am running Gnome openSUSE 12.3 with kernel version 3.7.10-1.1-desktop.

Not sure what happened, but it was somehow resolved…thanks.
