I have tried posting to openwrt forum but didn't get ab answer so trying here as this forum is more specific to wl500gp.

The maximum speed I was able to get between an HP 802.11g wifi laptop and a desktop (100 Mbit network / cable) was 9 ~ 10 Mbits/s. Both connected to Asus 500gp running openwrt RC5.

Laptop ====Wifi==== Asus 500gp === wired=== desktop

$ wl -i eth2 rate shows 24 Mbits, when I start downloading it drops to 18 but I'm getting a maximum of 10 Mbit/s real speed only, changing this using the wl -i eth2 rate rate doesn't help.

Laptop shows 54Mbits when connected. The weird thing is that before I got the Asus, I had a noname pci wireless router for 10 euros and I used to move big files between the computers at more than 2 Mbytes/s which is double the speed I'm getting now. Same config, same encryption on both.

wl0_akm=psk
wl0_infra=1
wl0_ifname=eth2
wl0_mode=ap
wl0_gmode=6
wl0_ssid=xxxxxxxx
wl0_closed=1
wl0_macmode=allow
wl0_wpa_psk=xxxxxxxx
wl0_wep=disabled
wl0_wpa_gtk_rekey=3600
wl0_radio=1
wl0_maclist=xx:xx:xx:xx:xx:xx
wl0_channel=6
wl0_crypto=aes

I have tried the speed with wl0_akm=open and I was able to get around 15 Mbits/s. Anybody can confirm the problem is on my side or in the config? Are you getting better speed over wifi? Thanks

Well, have you tried changing wi-fi channel, enabling frame bursting and switching to 54g only mode?

I'm running in 54g mode only, tried different channels but not frame bursting. I'll try to find out how to do so and test.

thanks

After some tests I added the following nvram settings:
wl0_frameburst=on
wl0_gmode_protection=off
With the right channel I'm hitting 2.1 Mbytes/s ~ 17Mbits/s which is fine for me.

Thanks a lot Oleg
