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.

        It’s your laptop on a docking station? Or otherwise connected via Ethernet AND WiFi? then it could’ve jumped into the other network, if you have more than one.
        Have you checked that your laptops IP is in the same subnet as your servers?

            Stupid question: Have you tried restarting the router, and all switches? And renewing the DHCP leases? The third thing I’d check after that is whether you have a broadcast storm or loop in your network. (I’m assuming you’re targeting IP addresses, not hostnames, already)

              “Have you tried turning it off and back on again?”

              But, no, that is good advice. I haven’t seen mention of full shutdown of the laptop, either, but mostly been skimming the comments so…
