The catch is, it'll cost you about $170, the price of the Asus RT-N66U router. All I can say is, no matter how I tweaked or set my Linksys N dual band router, my wifi performance at home with the 5 was poor, erratic speeds, limited range and obstacle penetration, my performance was only very good if I was really close to the router. Once the 5 had to pick up a signal through any walls, doors, or any distance from the router, things got very erratic and often slow, the wifi strength bars would constantly be bouncing from 1-3, mostly on 2, with reduced, fluctuating speeds. The 5 clearly had trouble getting and keeping a strong signal. The odd part was, my 4s was pretty much fine and was very steady and fast. It was really strange and annoying. I took a chance and bought the highly regarded Asus router from best buy today. INSTANT, 100% FIX, as if literally, the problem never existed, in fact, it's the best range and speed I've ever seen at home. Full bars regardless of where I am in the house. Rock steady max speeds, irrespective of distance from the router or obstacles. This router took my 5's really erratic and limited performance/speed/range, and made it the best I've experienced. I'm truly amazed at what the router upgrade did. Yes, I agree the 5 is partly at fault, since my 4s was working just fine (though not quite as good as the 5 is now). But it seems to me, the 5 has an antenna design/software that has issues with less than cutting edge routers like my 2 year old linksys N dual band. All I can say is, if you're frustrated by the wifi symptoms I described above, and don't mind upgrading your router to the Asus, I can all but guarantee this will solve your problem as if it never existed. I'm finally happy with my 5. You shouldn't have to buy this router to get good wifi at home. All I'm saying is, if you're having these issues and want them solved, this will do it. It's up to you whether you want to spend the money to do it, or, try to exchange your phone, or hope for a software patch.
