URGENT: Help with weak signal!

So, I just started my seasonal job and I'm looking to pick up an ASUS laptop—nothing crazy, just something to run those older games I've been playing for years whenever I get some downtime. Here's my dilemma: I'm living out in a rural farmhouse area where my cell signal is basically non-existent... so I was thinking about grabbing a cheap USB modem/dongle, maybe some kind of antenna or whatever else I can find to grab a neighbor's Wi-Fi signal. I might even need a signal booster if that's actually a thing. It’s a pretty small, isolated spot, and while the signal in town is decent, the only reliable provider around here is Xfinity, which everyone uses. I’d prefer something mobile via a USB stick so I can take it with me later. I could really use some advice on the gear needed to pull this off—if anyone can explain what I should be looking for here in the States, I'd appreciate it.
Basically, I need
- A Wi-Fi antenna? Maybe a link to something decent and affordable—or at least a link (maybe on eBay) so I know exactly what to search for.
- A signal booster (links would be great here too).
- Any necessary extra gear or specific cables.

I'm just a hobbyist with zero technical experience, so I'm a bit lost.
THANKS IN ADVANCE FOR THE HELP 🙂
