I use one of these:
Nano Station Loco M-2I had an older "High power" wi-Fi adapter but this puppy amazed me when I hung it out
It can "Mount" on any "pole" I mount it on a flag pole. on the mirror arms on the bicycle carrier any vertical pole Mounting it on the flag pole (in a camp ground. you likely won't need this) gives me the abilty to see OVER other RV's instead of through them (More range).
It feeds a standard Home/Small office router inside the RV.. and that feeds 5 computers (3 windows 2 chromebook) a tablet, my phone and two DVRs.
Does take a bit of time and trouble to set it up. IF you decide to go this route PM me and I'll walk you through it but here are the basics.
Access router set up and set WAN IP to 192.168.1.1
Access 192.169.1.20 (Nano statioh)
Click on the 2nd tab
Do a search for your friend's SSID
Select it then click on LOCK TO AP
Then click on Change and apply (in that order)
click on main (May have to wait 30 seconds or so)
once you see a good STRONG signal on the signal meter
Go back to Router settings and choose Automatic IP address
And the job is done.. Oh, I change my Routers LAN ip to 192.168.someting other than 1, something.
