My wife, kids, and I, along with friends and in-laws enjoy camping. We go quite often to different campgrounds that have wifi and often they have very little wifi signal and very slow speed. With our kids trying to plan on the ipad, or watch movies, it makes it frustrating. I want to purchase a telescopic flag pole and mount a omnidirectional wifi antenna and hook it up to an old router to boost our signal. I read an article about turning the router into a repeater and I'm fine with that. However, how can I hook up the antenna to the router/repeater? The router is an old linksys with only ethernet jacks, can I use some type of adapter to convert from the antenna cord to ethernet? Thank you in advance for suggestions on my plan.
