CG wifi? Fuggedaboutit...
In the beginning when were newbies, we bought an Alfa brand wifi booster. Waste of money and did NOT help. Ended up giving it away.
You will find out pretty quickly how bad CG wifi is. If many kids there, when they get up in the morning and start streaming, it kills the already BAD wifi. Many people have to go to a CG clubhouse where it's close to the antenna to get a better signal, but even then it can be a painful struggle.
We've been using a Verizon mifi hotspot for years now. Last year DW used her phone as a hotspot a few times. Depends on your data plan too since you can suck it dry pretty quickly depending on what you're doing on the internet. Sometimes the Verizon or DW's cellphone signal can be quite weak in some locations, like the Oregon coast for ex.
