I have a Linksys e4200v2 and I'm hoping to somehow install an external antenna on it in order to improve the range of the router. I've seen some "kits" advertised, like this one on ebay, but I'm not sure how legit it is. Does anyone have recommendations for this project, or is this a really good way to brick my e4200v2? Maybe it's not worth the effort and I should just pick up a AC router and AC access point...
