Questions about this item:

Shopper  Why Did You Choose This?
JONATHAN C  "The Wirecutter" web site recommended it
Prakash H  Which should I choose between RT N65U or RT N66U and why?
PHILIP K  The differences in spec are mainly the 66 has a faster wireless speed of up to 450Mb/s whilst the 56 is rated at 300Mb/s. The 66 offers more "features" like a built in print server but whether you need the extra facilities only you can tell. Like all top models manufacturers load them with features but whether they are worth the money is questionable.
hall g  is this router Mac-compatible?
GREGORY S  Yes, because IP Routing and Router Management are independent of Operating Systems and URL Browsers.
