How can I tell if the place I'm staying at has a shitty router, or just shitty service?
See router's specs, watch if the load it is bearing reaches easily its limitations.
It is most likely some people torrenting at the place you are in, install a firewall that handles such a thing

Yes, but much more if you take time to learn.
For example, a server with some network cards (good equipment) and pfsense is very good for a company with some 100+ employees.
