Tp Link MR3420 Wifi bridge/repeater issue

[Batublock]

Hi,
I'm buying this tp link tl mr3420 router for bridge it to my P1 Wimax Router(Internet acces). i'm using WDS feature in stock firmware and its not working like i expected.

So i found this gargoyle firmware and flash it to this tplink MR3420. Configure bridge/repeater connection and succesful to bridge it to my P1 router. BUT the problem is i just can connect to the network using LAN cable only. All my wifi device can't connect to the ssid and it said something like "security mismatch" after asking for WEP password.

I'm kind of stuck in here.I just want my router be a wifi repeater only.
i just upgrade the firmware to 1.57 - not working
using diffrent ssid - not working
disable all the security - not working
Any suggestion wil be appreciate.
Thanx
