I am by no means well versed in networks, I have some “set it and forget it” tp-link Deco m5 mesh, with one of them set up as the router, linking wirelessly to another two units.

This has worked without a single issue for years…

I used my laptop earlier today, was watching a show from my home media server in the jellyfin application. Got interrupted and just closed the lid on my laptop. A few hours later, my laptop can’t access anything on local network.

It connects just fine to my wifi and has internet access. It just can’t connect to any device on my local network.

Aside from my server which has a static IP, all IPs are just assigned with DHCP, as far as I can tell there are no duplicates.

All other devices connect to each other as usual, only my laptop is acting up. I’ve tried resetting network connections on the laptop, that didn’t work. Obviously tried a reboot, but also didn’t work.

I’m running Linux mint on the laptop.
