I'm trying to set up an old computer as a Minecraft home server and I'm connecting it to my router using WiFi since I don't have enough ports available. The problem is, I can SSH into the server from my phone using Termux without any issues, but when I attempt to SSH from my computer connected via Ethernet to the same router, I get a timeout immediately and can't ping the server at all. I'm looking for some advice on how to resolve this issue, especially since I can't just plug in a cable. By the way, I've tried this with both Debian 12 and Ubuntu Server.

Here are a few troubleshooting steps to consider:
1. Try pinging or SSHing from your phone to any other computers on the network.
2. Check if the other wired computers can see each other.
3. Make sure all devices are on the same network.
4. Confirm whether DHCP is set up on all machines to avoid subnet issues.
5. Double-check if your WiFi access point and router are the same device or if there’s a separate router in the mix that might be firewalling traffic or creating a different network layout.
It sounds like your router might have a setting like "AP isolation" which separates wireless and wired clients. This could be preventing your computer from communicating with the server. Check your router settings to see if that's the case!
How would I go about fixing that? Any specific steps to follow?
I can't check the first three points right now, but I think my Ubuntu server is using DHCP by default. My Windows computer might be a different case. Also, the WiFi access point is integrated with the router, but I do have a TP-Link range extender.
