That the Wifi "works" may not be what you are used to- it may work, but be quite slow or there may be limited, rather than unlimited data. So if and when you do make contact with the host, try to get some indication of what kind of service you can expect. And even if they do have high speed, unlimited Wifi, be aware that the infrastructure in Mexico isn't all that great, so there can be outages which are beyond the host's control.
You can also buy a Mexican SIM card for your phone if your phone is unlocked, and put internet time on it, which would be cell-based rather than Wifi, and tether your phone as a hotspot to a laptop. This is actually how I get my internet, as there aren't any phone lies out to where I live. It's a expensive way to get internet, though, if you have to do things which are heavy data sucks, like Zoom calls, and you wouldn't be able to stream Netflix or anything or you'll motor through the data really fast.
