So let me get this straight.
You have 11.ac for the wireless which can get real world performance at near gigabit speeds, but you can only talk to faster wired devices like desktop computers and servers at 1/10th the speed?
That's as ridiculous as having an 11.n router and only using it for a 15Mbps DSL internet connection when 11.g is already overkill for that kind of application.
I picked up a nice $200 ASUS router a few months back that was a net wash. It came bundled with 2 games that I did not want and sold. It replaced my old 11.g router, which I also sold. It also replaced my gigabit switch I had been using, which I also sold. After all was said and done I made $25 by upgrading to 11.ac
... now if only I had any 11.ac devices in my home...
