100% CPU consumption, interfaces are gone, Winbox disco

RouterOS General

Hi All,
Anyone have any suggestions? I’ve been having a hard time getting configurations to save with an RB433AH I recently purchased. Suddenly the WLAN1 interface became disabled and I couldn’t get it back then all interfaces dissapeared with timeouts and when I check System Resources CPU is 100%.
I’ve tried hitting the reset button, powering on and then releasing with no change in status.
Any ideas? I’m stuck!
Thanks,

if you are connecting via MAC address, then it’s normal. You should apply an IP address and connect that way. MAC address connection is not reliable

What if this happens when you’re using the IP, not the MAC?

This is what I’m seeing.
