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)
It is not in a dock. Yea, subnet of laptop is the same as the rest of the network.

“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…
