I decided to try a usb wifi adapter. The camper next to me left and I have a direct shot to the rv park wifi. The Netgear A6210 adapter has helped, I can tell by the number of networks I can see now that I couldn't before installing it. But, the bottom line is, this RV park wifi is just poor, and, I am sure that most are. You cannot improve that. Putting a antenna on the roof, which I was considering, would not improve that, except, maybe in the case of being totally blocked by another camper. If I want a better connection I just have to use my phone as a hotspot. But I try to conserve my data by using their connection. Thank you everyone for your replies, Dave
