The following testing was based on the initial custom beta firmware.

Basic Setup for UniFi

WiFi Test @ 2.4GHz

Overall 2.4GHz wireless performance is stable & consistent, the speed ranging between 11~13MB/s is considered quite good ! Smile


WiFi Test @ 5GHz


2012-11-03 13.00.48-4300-5g.jpg2012-11-03 13.01.44.jpg2012-11-03 13.05.40.jpg2012-11-03 13.07.49.jpg2012-11-03 13.10.01.jpg2012-11-03 13.12.19.jpg2012-11-03 13.13.22-LANTest.jpg2012-11-03 13.19.57.jpg2012-11-03 13.23.16.jpg2012-11-03 13.31.53.jpg

No matter how I change/adjust the settings, the overall 5GHz wireless performance is rather disappointing, the speed is not better than the 2.4GHz .... Frown
I'm not sure whether it's the firmware, settings or hardware issue .....


WiFi Test - Bridging with ASUS EA-N66

Worrying the poor 5GHz performance might be due to my laptop adapter, I pull out the EA-N66 and setup bridging link with the TL-WDR4300 :

2012-11-03 13.43.42-EA66.jpg2012-11-03 13.46.18.jpg2012-11-03 13.48.50.jpg2012-11-03 13.51.48.jpg2012-11-03 13.54.43-LANTest.jpg2012-11-03 13.58.56.jpg2012-11-03 14.01.42.jpg

Still, the 5GHz spectrum performance is still poor, I'm puzzled to see the average Write speed (~15MB/s) is faster than Read speed (~12MB/s) ... Sealed
I suspect it would be firmware/driver related issue ....
