I don't think any of the Cabins have Wi-Fi. There is a secure Lounge area in a separate cabin available with computers and Wi-Fi. I used it several times and it was OK. Our cabin was just across the parking lot from the Wi-Fi Lounge, and we were not able to pick up the Wi-Fi signal.
Our Cell phones worked just fine... AT&T
No need for Air Conditioning. These cabins have a bit of a rustic feel. We did have a ceiling fan and a large window. We were quite comfortable.
