ath5k AP support?

ath5k AP support?

[Tomasz Chmielewski]

According to http://linuxwireless.org/en/users/Drivers/ath5k, AP mode is 
"reported to work, we just need some further tests on all cards to be sure".

I just tried it with 2.6.30 kernel with this card:

00:02.0 Ethernet controller: Atheros Communications Inc. AR5212/AR5213 
Multiprotocol MAC/baseband processor (rev 01)

And it doesn't work:

Is there anything more needed for ath5k to work (some external patches, 
git tree etc.)?

I tested it on ASUS WL-500gP (BCM47XX mips platform).

That's for the wireless-testing.git.

The AP support is not in Linux 2.6.30.  I believe it will be in Linux
2.6.31.

2.6.30 does not enable AP mode, you should try the wireless-testing
tree instead.

There is at least one known bug (the patch at the end is broken but
close):  http://bugzilla.kernel.org/show_bug.cgi?id=13237

I tried compat-wireless-2009-06-17, but I can't connect:

I didn't try your patch.

Oh well.
The above is with hostapd 0.7.0 snapshot.
With 0.6.9 I can connect and the connection works fine

Is it normal?

hostapd 0.7.0 snapshot worked with a b43 card (but my b43 card doesn't 
work well on my ASUS router, and hence I'm trying a different card, ath5k).

I'm not sure -- do you have anything in dmesg?  

I've noticed a strange bug lately where some packets to the STA get dropped
due to some kind of off-by-u32 bug.  I haven't tracked it down yet to
any certain combination of ath5k/w-t/hostapd, though.

No, nothing in dmesg.

I checked out 0.7 now, and it seems to work.

So, problem solved.
