Setup BGW320-500 to Allow Minecraft LAN

I have a BGW320-500 router with AT&T Fiber internet and am trying to configure my router's settings to allow me to host a Minecraft LAN server over my home wireless network (Note: this is NOT the same as hosting a multiplayer server for players on different networks, which requires port forwarding, etc.). This simply requires allowing two computers to communicate with one another over the same Wi-Fi network.

I have gone through all the recommended troubleshooting steps for setting up a Minecraft LAN server (Windows Firewall settings, turning on network discovery, etc.). One of the troubleshooting steps recommends disabling "AP Isolation" in your router settings (which led to success when I previously had Xfinity internet service/router). I have seen in other AT&T forum posts that this setting is not available with AT&T routers. Is there a similar/alternate setting to achieve the same result?

After hunting around my router's settings, I have a hunch that the Firewall>IP Passthrough page may hold the solution (not totally sure though). The description for the "Default Server" Allocation Mode says "Allows the device to forward all externally initiated IP traffic (TCP and UDP protocols only) to a default host on the LAN". I selected this setting and chose my computer from the Device List and saved the settings, but still no luck getting my Minecraft LAN server to appear on the other player's list of servers to choose from.

Any help with navigating the countless pages of router settings to solve this problem would be greatly appreciated. Thank you!

That Default Server setting is for traffic coming in from outside of your network so no surprise that it didn't help.

Can the two computers communicate over the network in any manner?

@tonydi I tried pinging the other computer via Command Prompt and it failed. Any other specific ways you had in mind for testing communication between the two computers?

No, that's fine.  So it's not a Minecraft issue, it's some sort of network issue between the two computers.

Too many possibilities to outline here but there are tons of great tutorials online about things to check when Windows machines can't see each other over the local network so I'll point you in that direction.
