I am running a RB500R5 with OS 3.6 that is reboot every 10 to 30 min. I have replaced all the equipment. Same problem on both setups.

The system has 3 Wireless (Atheros AR5213) cards. One is setup as a WDS backhall, the second is setup as an access point (2.4), the third is not turned on it will be for a second access point (900)

I have the watchdog turned on an pinging a local address. If the Watchdog is turned off the system hangs and requires a hard reboot via cycling the power.

What am I missing?

What additional information do I need to supply?

My router board firmware is as follows
routerboard: yes
model: "532A"
serial-number: "14FA01C7D22C"
current-firmware: "2.12"
upgrade-firmware: "2.12"
