talk to more distant wifi access points (APs)
repeat that link to the RV
Since I don’t have a few hundred bucks lying around but I do have a WRT54GL router I picked up for $8 at a garage sale, I decided to set that device up to repeat open wifi APs. Here a straightforward tutorial to making it work.
That takes care of #2 up there. #1 is addressed by either having the router up high away from metal walls (overcab area?) or mounting a better antenna. I’ve done it the first way in a residential setting before.
I’ll try out a couple different antenna options next. A yagi is on the way.
