hAP ax3 Routing stopped working

RouterOS Beginner Basics
1

I have a hAP ax3. I setup using the QuickSet feature to setup initially. It has been working well. Recently, I lost internet connectivity on devices connected to this router, despite the router itself being able to ping the main router.

  • I initially had the internet cable connected to ether1, but devices couldn’t access the internet.
  • Using the terminal on the hAP ax3, I could ping the main router successfully.
  • I moved the internet cable to ether2, and now devices can access the internet again.

I’m puzzled because the hAP ax3 can communicate with the main router itself, but devices connected to it couldn’t access the internet initially. I’d appreciate any guidance on what might have caused this issue and how be able to put the internet back to ether 1.

I haven’t changed the routing (see below) but everything is working.

Are all ports bridged?
If so, then dhcp client should be set to bridge not ether1

I found the bridge and ports and somehow, ether1 was not listed as being bridged. I changed this so it is bridged again.

I changed the DHCP client to go to the bridge.

But the crazy question is why did this change?

Did you, by any chance, click around QuickSet? Using QuickSet (part of Webfig and Winbox, the “light version of UI”) is pretty dangerous if one ever configures anything outside QuickSet (many of us think that when user clicks WebFig button the first time, QuickSet button should simply disappear).

Are you using the hAP as a router or switch?
if as switch the bridge all ports, if as router remove ether1 from bridge and change dhcp client to ether1 and create a dhcp server on bridge
Set ether1 as WAN and bridge as LAN then apply firewall and nat
