I just upgraded to OpenSUSE 12.3 on my laptop and am having problems with the wireless network. I can successfully connect but after 10-60 seconds it stops working:
Code:

64 bytes from 8.8.8.8: icmp_seq=48 ttl=47 time=14.6 ms

ping: sendmsg: No buffer space available
ping: sendmsg: No buffer space available
ping: sendmsg: No buffer space available
ping: sendmsg: No buffer space available
The weird part is that if I have a ping running and it pauses for a few seconds, if I stop the ping and restart, it will keep pinging fine for another 5-10 seconds. If I just let it go I will get the above error. Also, If I stop the ping before I start seeing the "No buffer space" error, ping reports no dropped packets.
My card is a Broadcom BCM 4312. I've tried both the b43 and the broadcom-wl driver and they both have the same problem. I remember that I had this problem with a prior version of OpenSUSE, I think 12.0 or 12.1, I don't remember for sure. I was never able to get it working properly. I previously had 12.2 installed on the laptop and it worked without any problems.
Here are my configs.
