On our network, 80ms is, I should say, RELATIVELY fast.

Tear it down and rebuild it from scratch.

Ping from home to one of the servers at home is less than 1 ms. Ping to the office firewall is 16 ms (13 hops on the way, 40 km street distance). I've just logged in via VPN to the office network, and I get a constant ping of 16 ms to a random server in the office. I also pinged another system connected via VPN over LTE to the office network to get 52 ms ping time (another 15 km street distance away).

80 ms in a LAN is impressively slow. It sounds like some firewall or router in between your machine and the other machine that is very overloaded and/or very misconfigured. Or you have a severe cabling problem.
