No communication between wl500g and wl500g deluxe

[ugriz]

HELP PLEASE...

Something is wrong they aren't communicate if I reconfigure them (IP addresses, SSID, etc...)

Earlier they worked in WDS mode but now, they (sometimes) "see" each other only if I reset them on factory defaults. I tried everything, change firmware, reseting, import config files (from time when they work) but nothing. There is my config files in attachments. Curently firmwares are 1.8.2.4 on wl500g and 1.9.4.6 on wl500g deluxe

Now what?

Any sugestions?

WL500g_NM.rar

WL500gx_F.rar

I see that all of this happens only if I change authetication metod in WPA-PSK, WPA or RADIUS...

They work if I use WEP Encryption...

What now?

After three days work, those two routers simply reduced speed about five times. Did anybody know what is happening?

They function normally about 6 months, range between them is aprox. 5 km, antenas that I use are two bi-quad+dish (135cm diametar). I use netstumbler to check air, but everuthing is like before six months. I'm gonna go crazy....
