Linksys WRT1900AC Wi-Fi router: Faster than anything we've tested

When Linksys first showed me a WRT1900AC prototype last year, I thought to myself, wow: I hope its performance lives up to its audacious looks. The good news is that it does--for the most part. In fact, it's the fastest router I've ever tested. The bad news is that its $280 MSRP marks it as the most expensive router I've ever tested (Linksys launched the router with a $250 sale price).
