Title: Poor WiFi Performance

I'm currently running Ubuntu 14.04 and have Firefly connected to my home network via 802.11n (2.4Ghz).

With "Firefly-RK3288_Server_Ubuntu14.04_201501271052" I'm seeing 300 kB/s - 1 MB/s.

Other devices in the same room get fairly good bandwidth and reception whereas I'm seeing about 1 MB/s with Firefly. I've also noticed poor WiFi performance in Android as well with the "Firefly-RK3288_Android4.4_201501271047.img".

Here's iwconfig. I turned off power management and the signal seems strong.

wlan0 IEEE 802.11 ESSID:"ESSID"

Using the "Firefly-RK3288_Ubuntu14.04_201501271612.img" image:

Speed test:

On a Macbook Pro in the same room:

I will test with the latest Android image and update again.
