Currently, I left the wifi wide open. No security enforce. The weird point to this issue is whenever we unplug the antenna from the unit, the device working fine. But then we plug it back, the device goes haywire.

What is the build you are using on FWF60C? Also can you check if CwWtpd process CPU usage is high when the wifi signal drops.

Could it be that the Pizza Hut is sending deauth packets thinking you are a rogue access point, clogging up your CPU?

Is there a way to check? I don' t see anything in the logs. Whenever the CPU hit 70% or more, the wireless SSID drop out of range or completely disappear. Sometime we see the SSID and attempted to connect but no avail.
