problem with 433ah

Dear Normis
I am running RB433Ah with 3 compex wireless cards in base-station and when I am inserting the radio cable in switch, the self ping of the radio is going in 4 digits. This scenario is coming in bench test, and I had tried by changing the firmware.
Can you help me, urgently

try to reset the device into default settings /system reset

Tried, but not working. Can you give me 3.20 version firmware because on this all the devices are working fine, but 1% I want to make sure by downloading with 3.20 firmware.
