My computer isn't visible to the local network until I ping something (lemmy.world)

I have a samba shared folder that I use to share files between my pc and another windows pc on my local network. That folder will be unreachable from the windows PC until I ping it's IP address, then it'll be reachable.

The same happens for KDE Connect. My phone will be unreachable until I ping it's IP address, then KDE Connect is usable.

I'm on Ubuntu 22.04.3 LTS. I'm using KDE Plasma 5.24.7. I'm using UFW for my firewall. I've run "sudo ufw allow samba" to allow for samba to work on the local network. I have a TP-Link Router, the AX1800.

How do I solve this issue? I can think of a workaround using cron to ping the devices I need to ping, but I feel like there has to be a better solution.

Thank you!

Do you have power settings on any of your devices that put the NIC to sleep or into standby?

Not to my knowledge. My computer is set to stay on indefinitely. The screen doesn't even turn off unless I shut down the PC.
