I have configured one router as an ap using Avila GW2345 boards with 1 atheros mini pci card in each.  The access point works great for all of the wireless pc connections that I current have.

I have configured a 2nd router board in sta mode and connected to the first ap.  whenever I do a ping test I get major packet loss and unusually high ping times.

The access point is at 192.168.1.90, and I can ping it all day long and never lose a packet from laptop, but I'm losing 40-50% with using sta mode from the other router.

Anyone got any ideas?

Check & setup distance....
..... i'll got something like this when i no setup distance & my link was 3km...
.... i'll check by GPS how long between ap & sta....
..... & all fine smile
May be help wink

I doubt it is distance related since I'm only about 50 ft away.  Strange that it's only sta mode that's having this issue.

Same problem here.

http://wiki.openwrt.org/ClientModeKamikazeStyleHowto

2007-12-01 — Tried routed client-mode again with Kamikaze 7.09 and Broadcom WiFi does not work good (very high ping times and dhcp does not always works reliable, I'll test it in a few month again)

Hi!

I have the same problem. Ping is slow and lots of packets are dropped. Sometimes, the router even reboots by itself (after 5 -10 min). I tried to disable the firewall thinking that could be the source of the problem, then,  sometimes it works, sometimes not. (looks random)

Here is my config:

Router: wrt54g V2.2, Kamikaze 7.09
AP: ZyXEL P-660HW-D1 original firmware, V3.40(APC.1) | 02/10/2007

/etc/config/network 

#### VLAN configuration 
config switch eth0
        option vlan0    "0 1 2 3 4 5*"

#### Loopback configuration
config interface loopback
        option ifname   "lo"
        option proto    static
        option ipaddr   127.0.0.1
        option netmask  255.0.0.0


#### LAN configuration
config interface lan
        option ifname   "eth0.0"
        option proto    static
        option ipaddr   192.168.0.1
        option netmask  255.255.255.0

#### WAN configuration
config interface wan
        option ifname   "wl0"
        option proto    dhcp

/etc/config/wireless

config wifi-device  wl0
        option type     broadcom
        # option channel  4

        # REMOVE THIS LINE TO ENABLE WIFI:
        # option disabled 1

config wifi-iface
        option device   wl0
        # option encryption none
        option mode     sta 
        option ssid     Stardust
        option encryption psk
        option key      "secret passphrase"

running ifconfig gives this:

I'm not having any problems with sta on 7.09, it's been working well for months ... I haven't tried the latest from svn though.

Looks to be something to do with the encryption...

This is what I get on another AP, with no encryption: (wrt54gl V1.1)

PING 192.168.1.1 (192.168.1.1): 56 data bytes
64 bytes from 192.168.1.1: icmp_seq=0 ttl=64 time=1.9 ms
64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=3.0 ms

64 bytes from 192.168.1.1: icmp_seq=10 ttl=64 time=2.1 ms

--- 192.168.1.1 ping statistics ---
11 packets transmitted, 11 packets received, 0% packet loss
round-trip min/avg/max = 1.8/2.1/3.0 ms

I need to check though, if the problem comes from the other AP. (by turning encryption ON on this one...)

The discussion might have continued from here.
