Hi! I build a wireless access point using a-link wl54pc (pcmcia card, rt2500pci module) and hostapd 0.6.9 with kernel version 2.6.32-rc5. Problem is that even tho hostapd starts and iwconfig shows wlan0 in master mode, other computers cant find the wireless network.

I found a working patch from here: http://rt2x00.serialmonkey.com/phpBB/viewtopic.php?p=32632#p32632 and all works now with it applied to vanilla kernel. Just wanted to post this to the mailing list and ask why it's not added to mainline rt2x00 kernel tree yet? Patch on forum is from May, almost half year ago. Hopefully it'll be included to mainline kernel asap.

This is an old one -- sorry if no one got back to you sooner! It looks to me like the equivalent of the patch you cited is available in 2.6.34-rc1 (if not before) -- look for DRIVER_REQUIRE_DMA and rt2x00queue_align_frame. There were some changes between 2.6.32-rc5 and now, but I'm not sure if they affect things for your or not.

Could you try 2.6.34-rc1 and see if things are working for you?

Thanks!

John

This indeed ought to be fixed already in mainline. Investigations show that a fix similar to the mentioned patch (in a different place in the rt2x00 code) was included in 2.6.32.
See commit 93354cbbcbfca920495377158c0f61c36be79e13 of Linus' tree.
