I installed an Alfa wi-fi extender. We don’t use it much. It’s a bit fussy to set up (my skills are limited). It might be fine if we stayed in the same place that had good wi-fi available. It seems most campground wi-fi is overloaded. We mostly stream content with cell phone/ hotspot
If you are trying to hook up to your brothers wi-fi a simple window mounted antenna might do the job.
