Here's my situation: I'm shopping for a wireless router. I live in a pretty big house with lots of metal everywhere, so I'm looking for something that can broadcast a good signal through all that (by the way, this isn't speculation; we've had some trouble finding a cordless phone that worked well). While browsing online I realized that a router's performance in this situation isn't easy to tell from product descriptions and reviews; they usually go on about the security features and all the fancy stuff which I don't really use.
Since it won't be easy to find the kind of router I'm looking for and I don't have a huge budget, I figured it may be simpler that just get a common router and then buy a good antenna, which is more likely to be made for this specific purpose.
My question is: does this make sense? Does it make sense to buy a not so special router and then slap a better antenna(s) on it?
