New kernel recommendations for ath9k

New kernel recommendations for ath9k

[Luis R. Rodriguez]

For those not subscribed to the ath9k wiki on wireless.kernel.org [1]
(which we recommend you do if you're a user) here's a quick note to
let you know our latest kernel recommendations for using ath9k:

  *  >= 2.6.27.22
  *  >= 2.6.28.10
  *  2.6.29

If you want 802.11n support or AP support you'll want at least 2.6.29.
If you happen to have one of our new 1x1 AR9285 devices (all AR9285
devices are 1x1) then you'll need at least 2.6.29. If you want to
start using ath9k on APs with AHB you will need at least 2.6.30 (still
in RC series).

As usual if you happen to be stuck on older kernels for one reason or
another you can always use compat-wireless [2] and if that happens to
be a little too bleeding edge we have now compat-wireless releases for
stable kernel releases, starting as of the 2.6.30-rc series [3].

Thanks for the update.  If i want to use multiple AP's with Ath9k it it 
still best to use wireless-testing?  Is multiple AP support in 2.6.30-rc 
series net-next or wireless-next?

Thanks.

Yeah wireless-testing is best for that. I should also mention that if
you want to use AP mode you want to be at least on 2.6.29 (your own
kernel, not the compat-wireless one) if you care about Power Save
buffering on the AP as otherwise even if you use a compat-wireless
with code from > 2.6.29 those frames will be dropped. IIRC its due to
the way we use skb->cb for this and there not being a clean way to
backport this (so we just drop them).

N isn't "greater than" G. N is more features than G. Just set the N
options in the config file. You may need a git hostapd, I don't know for
sure.

Also, please set your clock and timezone correctly _before_ you say
"thank you"!. You have posted on

which is clearly impossible.

Thanks for the kernel info.

How do you configure hostapd to work in N mode with ath9k?  Currently 
the hw_mode parameter found in hostapd.conf does not accept anything 
greater than g.

Thanks
