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.

  1. wlan0     IEEE 802.11  ESSID:"ESSID"
  2.           Mode:Master  Frequency:2.437 GHz  Access Point: XX:XX:XX:XX:XX:XX
  3.           Bit Rate:39 Mb/s   Tx-Power:32 dBm
  4.           Retry min limit:7   RTS thr:off   Fragment thr:off
  5.           Encryption key:off
  6.           Power Managementmode:off
  7.           Link Quality=4/5  Signal level=-67 dBm  Noise level=-92 dBm
  8.           Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
  9.           Tx excessive retries:0  Invalid misc:0   Missed beacon:0
Copy the code

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

  1. wlan0     IEEE 802.11  ESSID:"ESSID"
  2.           Mode:Master  Frequency:2.437 GHz  Access Point: XX:XX:XXX:XX:XX:XX
  3.           Bit Rate:72 Mb/s   Tx-Power:32 dBm
  4.           Retry min limit:7   RTS thr:off   Fragment thr:off
  5.           Encryption key:off
  6.           Power Management:off
  7.           Link Quality=5/5  Signal level=-57 dBm  Noise level=-91 dBm
  8.           Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
  9.           Tx excessive retries:0  Invalid misc:0   Missed beacon:0
Copy the code

Speed test:


On a Macbook Pro in the same room:


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