So I received my atheros AR5005GS mini-pci card and replaced the original one. I compiled kamikaze from SVN (latest revision, last night) and flashed the firmware. So now I'm running the 2.6 kernel, and installed hostapd-mini. I configured the wireless connection and it's working so far. However, I have a very very poor signal strength and coverage. What am I doing wrong? Here's my config:

root@OpenWrt:~# uci show wireless
wireless.wifi0=wifi-device
wireless.wifi0.type=atheros
wireless.wifi0.channel=5
wireless.wifi0.diversity=0
wireless.wifi0.rxantenna=1

wireless.wifi0.disabled=0

wireless.cfg2.device=wifi0
wireless.cfg2.network=lan
wireless.cfg2.mode=ap
wireless.cfg2.ssid=xxxxxx
wireless.cfg2.encryption=psk
wireless.cfg2.key=xxxxxxxxxxxxxxxxxxx

Turn off wireless diversity, and enable only one antenna.

wireless.wifi0.diversity=0
wireless.wifi0.rxantenna=1
wireless.wifi0.txantenna=1

isn't this exactly what that is?

If you look at my first post closely I already disabled diversity. It doesn't help.

Hello,
I also have Asus 500gp/Atheros and my signal is also a bit poor.  Anybody else ?

Have you connected the antenna to the MAIN or the AUX connector? If last, try setting rxantenna and txantenna to 2, perhaps you were trying to use the wrong connector (happended to me, changing it to the correct one resulted in fine reception).

Hi,
in my case I tried to changed the TX/RX Antenna to "2" but the signal has a big drop in this case so I guess I connected the antenna correctly to the main connector. I don't know if this is a big issue but I have 2 times the diversity param listed and in the 1st one there is missing a "y" :

root@OpenWrt:~# uci show wireless | grep wifi
wireless.wifi0=wifi-device
wireless.wifi0.type=atheros
wireless.wifi0.channel=4
wireless.wifi0.mode=11g
wireless.wifi0.diversit=0 <--- here
wireless.wifi0.disabled=0
wireless.wifi0.distance=3
wireless.wifi0.diversity=0<--- here
wireless.wifi0.txantenna=1
wireless.wifi0.rxantenna=1
wireless.cfg2=wifi-iface
wireless.cfg2.device=wifi0

Edit. I had this duplicated value in /etc/config/wireless .. dont know why.
