All WAP Connections Across LAN Drop When Internet Goes Down

MicroTik Routerboard WAP
ID: RBwAPG-5HacT2HnD-US

WAP goes back to an unmanaged switch which serves the entire LAN. That unmanaged switch also handles the incoming connection from the internet/router.

Several wireless devices attach to to the WAP and establish remote connections through the WAP to various other wired devices across the LAN.

The issue is that when the incoming internet pipe goes down, all the wireless connections from wireless devices to other devices across the LAN are dropped. During that time, the WAP will not reply to pings by IP wirelessly, nor can the WAP be accessed via a browser wirelessly. Once the internet comes back up, wireless connections across the LAN can be resumed.

I’m not seeing anything in routing or NAT that would be responsible.

As I’m not too familiar with this unit, I try to use the browser based GUI for all adds/removes/changes.

Thanks in advance for any assistance.
