Description Tom Arnold 2013-04-15 17:17:14 UTC

In my home network I have a Belkin router with an older DD-WRT firmware. Everything was running fine with Windows 7 and Ubuntu 12.04.
Trouble startet with the new OpenSuse (12.3?) with kernel 3.7 on my desktop machine. Wired networking would just stop working.
Same problem on my netbook with Ubuntu 13.04 and wireless networking, with 12.04 and kernel 3.5 things are much better, with 3.2 it was perfect.
I tried installing Fedora and Arch on my desktop, but the problem persists with kernel 3.8. My wild guess is that newer kernels networking code rubs my Belkin router the wrong way, but I don't know what kernel settings I need to change. Thanks in advance.

I still have the problem with newer kernels.
