9.713 - AP30 WiFi crashing frequently?

Hi, I recently added an AP30 rev2 to my home, on WiFi channel 1.

My pre-existing AP50 is on channel 11, and I moved it to the far end of the house. (I'm going to unplug it also and move the AP30 to channel 11 to rule out all interference.)

Since adding the AP30, multiple clients (3 phones, 2 tablets) are frequently getting disconnected at the same time.

I suspect the AP30 may be crashing/rebooting.

What should I look for in the wireless.log to check for possible crashes?

Thanks!
Barry
