Of course I look at the RT-AC88U, drool and think, must have...
The thing is I have very basic needs. I have three apple tv's, iPads, iPhones, Macbook, Xbox one, Xbox 360, Windows laptop, printer, wireless thermostat and TV's on the network. For the most part my RT-AC87U has been rock solid. Our set up is standard stuff for a standard family.
I don't transfer any large files over my network. I don't even have fiber to my house yet... max speed from ISP is 25mbps!
Would I see any improvement at all if I were to upgrade to the RT-AC88U? Is there any point seeing as the RT-AC87U in my environment, has been extremely reliable.
