Hardware: 2x Linksys WRT54G Vers 2.2
Software: White Russian RC5
Encryption: WPA

Hi I have 2 WRT54G one is in AP  mode and the other is in wet mode.
If i turn WPA on my client  WRT54G can't connect to the AP.
Other Hardware (PDA, Laptop etc..) work perfekt.
It also works if i use WEP.

My Settings:

AP:
mtd -r erase nvram

nvram set wan_hostname="master"
nvram set lan_ipaddr=192.168.1.2
nvram set lan_dns="192.168.1.1"
nvram set lan_gateway="192.168.1.1"
nvram set wl0_mode=ap
nvram set wl0_ssid=OpenWrt
nvram set wl0_channel=4
ipkg update
ipkg install nas
ipkg remove dnsmasq
nvram unset wl0_crypto
nvram set wl0_wpa_psk="63chars"
nvram set wl0_closed="0"
nvram set wl0_crypto="tkip+aes"
nvram set wl0_akm="psk"
nvram set wl0_wep="disabled"
nvram commit
reboot

Client:
mtd -r erase nvram

nvram set wan_hostname="slave"
nvram set lan_ipaddr=192.168.1.3
nvram set lan_dns="192.168.1.1"
nvram set lan_gateway="192.168.1.1"
nvram set wl0_mode=wet
nvram set wl0_ssid=OpenWrt
nvram set wl0_channel=4
ipkg update
ipkg install nas
ipkg remove dnsmasq
nvram unset wl0_crypto
nvram set wl0_wpa_psk="63chars"
nvram set wl0_closed="0"
nvram set wl0_crypto="tkip"
nvram set wl0_akm="psk"
nvram set wl0_wep="disabled"
nvram commit
reboot

In wet mode the 'wifi' routine will enable the wpa supplicant that is built-in the broadcom driver wl.o.
So no need to load and run nas on the client in wireless extender mode (it is needed on the ap to authenticate wpa).
Make sure wl0_auth=0 as it may have become set through the WEP experiments.

ok.
i remove nas
and set wl0_auth=0
still same problem

eth1      IEEE 802.11-DS  ESSID:""
          Mode:Repeater  Frequency:2.427 GHz  Tx-Power:19 dBm
          RTS thr=2347 B   Fragment thr=2346 B
          Encryption key:off

some more things to try:
1) using identical wl0_crypto settings on ap and wet unit (just for elimination of causes; i agree that it should work with the ap allowing both tkip and aes).
2) check setting of wl0_infra to be enabled on both

After making changes, just give 'wifi' command to get the changed parameters to the radio and ping to see whether you get through.
When debugging i use the wl package. 'wl dump' will give you much info.

wl0_crypto is set to tkip on both devices
wl0_infra is 1 on both devices

did a little test with two spare v3.1 wrt54g boxes and rc5, one access point and one repeater, and it worked first time in wpa-psk with tkip crypto.
To help your debugging below is what various commands show on my boxes. I had to issue 'wifi' on the client to get it to associate after the ap had been rebooted.
