> It's 2015 and the best I can get from my 802.11n network is still ≈ 50mbps, even in the same room.

That's a pity. I have a two-antenna 802.11n client that gets between 160 and 200 mbps transfer rate one room away from the AP and between 100mbps and 160mbps two rooms away in the pipe-obstructed, tile covered bathroom.

Are you -by chance- trying to do 802.11n in the 2.4Ghz band? [0] If you are, and have any other networks around you in that band, that's a recipe for sadness:

* If you don't use 40Mhz channels with 802.11n, you'll -at best- only see slightly better than 802.11 a/g transfer rates.

* AIUI, if you try to use 40Mhz channels in the 2.4 Ghz band, you have to either use channel 1 or channel 11 as your base channel. You'll also be stomping on every other channel in the band. What's more, some APs will detect interference from other users in the band and automatically drop back to 20Mhz channels. (This is a long-winded way of saying that 40Mhz channels in the 2.4 Ghz band are often impossible for any urban or semi-urban site.) [1]

[0] If you're advertising the same SSID on both bands, and don't have band steering that you know works, you really can't rely on your client's software to be smart enough to prefer the 5Ghz band. WiFi client software is almost always oh so dumb and chooses signal strength over throughput.

[1] Adjust channel numbers and interference advice appropriately if you're not in the US.
