It got about 130 - 140 Mbps throughput, just exactly what I get from my other router which is 5Ghz but not AC standard.
It negotiates at much higher speeds (got 860 Mbps status), but only that max speed mentioned. Yes I know it shouldn'´t get that speed, but more than I got from the 5Ghz only router I guessed it should.
Another thing I've noticed is that when you try to change the channel bandwidth to 160 Mhz it doesn't work. It simply doesn't connect. Plus even if you try to revert the change back to 80 Mhz channel it doesn't work either. You have to reboot the router in order work again [looks like Windows ].
My expectation running the default 80 Mhz channel was to get significantly more than I get from my other 5 Ghz A standard router with 40 Mhz channel.
If anyone has any suggestions please let us know.
Regards,
160mHz bandwidth doesn't exist, which is why it doesn't work (i.e. no hardware currently utilizes a 160mHz channel width, and if I recall right, even though it's in the options, the WRT1900's radio drivers don't either).
In order to take advantage of 40mHz/80mHz channel width, the wifi card must also support VT/VHT [respectively]. There's also only a handful of channels in the 5gHz spectrum that transmit on a 40mHz channel width and none that transfer on a 80mHz width. You can see this by checking out the status page, which shows the channel width of the clients connected.
In order to obtain optimal wireless speeds, the wifi card driver settings must be tweaked to match certain settings to the router's. However, if you flashed 15.05 final you may want to flash RC3 as, currently, it's more stable.
You may already know this, but if you don't, the antenna positions greatly affect the speed you'll be able to obtain. They take a bit of tweaking to get just right, and it took me ~5 minutes of going back and forth between the the status page and the router to make minor adjustments to the antennas while watching the noise level and the registered speeds.
