Re: [arch-general] Wifi not working after kernel upgrade to 2.6.29

And this is new with 2.6.29? Because I know that the optional dependency of kernel26 on crda has been there for some time and I haven't needed crda yet. When I'm running 2.6.28 not having crda installed and having AP hidden, everything works without problems.

2.6.28 had static regulatory settings for "US", "EU" and "JP" built-in, and "US" was enabled by default. Active scans were allowed there on channels 1-11, but now the default changed to "World" and that is VERY restrictive. If you don't have crda installed, you cannot use any 802.11a channels, only channels 1-11 are enabled with passive scanning only and no adhoc.
