It's actually trivial to simulate a high-latency low bandwidth network on Linux with the traffic control subsystem, one need not switch networks at all.

  tc qdisc change dev enp1s0 root netem delay 300ms 200ms loss 10% 80%

This command delays all packets in and out of the wired interface enp1s0 300ms, +/- 200ms, with 10-80% packet loss.
