So I did exactly as I had planned and bought the Bear Extender. I would say that it worked okay, but not great. The issue was that it's USB attached, so the host computer had to basically remain stationary. Additionally, since the antenna was inside, it doesn't get as good a signal as if it were outside. When Bear Extender stopped supporting the model I bought, I decided to go the Wireless Bridge route.
So I picked up the ENH202. And while it's more than 3 clicks
it does work very nicely. I don't have it hooked up on the camper yet, but the testing at home is awesome. Basic steps:
1. Plug ENH202 into the laptop and turn off the wireless.
2. Reset ENH202, then access it at 192.168.1.1.
3. Enter network settings and select DHCP (click apply)
4. Enter wireless and scan
5. Select network
6. select apply
7. save and reboot ENH202
8. move ethernet cable to router input.
While it seems like a lot, it really isn't and can be done in a couple of minutes. I think that this will certainly give faster internet speeds while at the CG's
