Briefly, my RealTek adapter was just put to sleep by Windows on shutdown, and kubuntu could not re-awaken it (even in kernel 2.6.31-999).
I simply followed the advice given at the link above and told WinXP to leave the RealTek on (by starting the device manager, locating the RealTek adapter there, dbl-clicking it, and applying the following setting in the advanced tab: Wake-On-Lan After Shutdown = Enabled).
This behavior may be more general than I thought before. Lots of new *ubuntu users complain about very bad network support, which is of course a show-stopper for the transitionally-minded.
Maybe the Wake-On-Lan feature is now ubiquitous in the ethernet adapter world?
I guess that many newbies actually start off with a dual-boot installation, or just try the liveCD RIGHT AFTER WINDOWS SHUTDOWN (i.e. possibly with disabled network devices). The work-around is REALLY easy. But as an ubuntu/kernel/network bug, almost impossible to trace.
Maybe this hint (enable Wake-On-Lan if you experience network problems and if you're a double-booter, or try the liveCD from a windows system), could be included in the "known issues" section of the distro???
Whom do I tell?
What to do with this bug now? At least my comments and the one by IKT are probably misfiled, at least I imagine that the sporadic malfunction of a double ethernet setup is due to other problems...
Aaaah! I heff ze internet now!
The (trivial!) solution to the single- ethernet- adapter branch of the bug above was actually in
