You must be at 40 MHz to reach 300 Mb/s

Check the max connectivity speeds for your device, a quick google search should point you in the right direction, things to ensure that are set within the router are bandwidth 20/40mhz, security WPA2 AES, OBSS co existence = disabled
Also check on other devices if they are able to connect at 300mbps (PC with 5ghz compatibility)

for my android device:
- oneplus one
https://oneplus.net/one#features:

=> Wi-Fi 2.4/5GHz 802.11 b/g/n/ac
- nexus 10:
=> Wi-Fi 802.11 b/g/n (MIMO + HT40)
- nexus 4:
=> Wi-Fi 802.11 a/b/g/n 2x2
all android at 150Mbps max
yes, on the router, the bandwidth is set to 20/40mhz, security WPA2 AES, OBSS co existence = disabled
I've test with a pc (laptop), I have 300Mbps sometimes with this setting with 5ghz
other value I have seen on it: 150Mbps, 216Mbps, 243Mbps
it's not stable

If your can PC can connect above 150mbps, then this proves the router can output a signal at 300mbps.
Try changing the channel on the 5ghz band and also try to change the Regulatory Mode to 802.11h so see if the connection speeds settle down

To get 300mbps out of your android device you will need to use two spatial streams, which requires two antennas. Each stream/antenna can go up to 150mbps, most android tablets/phones etc only have one wifi antenna. It is actually possible to get 450mbps using the 802.11n wi-fi standard, but you'd need three antennas to do that!
So if you get it to connect at 150mbps you are doing really well.
[edit]
Just found this, maybe the Nexus 10 has 2 antenna after all... I will have to have a play as I have one...
