[ath9k-devel] N mode

[Dmitri Seletski <drjoms@gmail.com>]

Hello Guys.

If not mistaking, wireless N mode kicks in automatically. My Access
point is set to BGN  mixed mode. 99% of time i am only user of wireless
at home.
I have dilemma. I can't use cables in house, so wireless is only
solution, i have very quick broadband connection, we are talking about
over megabyte a second.

I wouldn't worry much about N mode, but my current speed on G, is only
600-max 700 kbyte  a second. Well, my wifi is bottle neck to my
broadband and it's very annoying.
To make things worse - I get disconneced very often.
I am familiar with console and reconnecting all the time manually is
just plane bad. Writing scripts to keep connection connected is even worse.

What can i do to improve speed and connectivity? Or in other words, what
should i do to enable N mode?(both devices are Dlink and N mode
compatible, thats what i bought them)

a little bit of system info:
my derivers: compat-wireless-2009-05-09

module in use:
/lib/modules/2.6.29.2/updates/drivers/net/wireless/ath/ath9k/ath9k.ko

uname info:
 2.6.29.2 #3 SMP PREEMPT Thu May 14 01:19:42 IST 2009 x86_64 AMD
Athlon(tm) 64 X2 Dual Core Processor 6000+ AuthenticAMD GNU/Linux

iwconfig output:
wlan0     IEEE 802.11bgn  ESSID:"dlink" 
          Mode:Managed  Frequency:2.462 GHz  Access Point:
00:1E:58:B4:F6:83  
          Bit Rate=1 Mb/s   Tx-Power=20 dBm

          Encryption key:off

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0


Link quality is typically between 55-58
Signal lvl between 42-55

I don't use any security on wireless at all(I live in rural area, you
know...), besides i do network inspection once in a while.

Any ideas or advices appreciated, thanks.
