Title: Slow 5GHz AC Wi-Fi
Post by: JayceOoi on December 19, 2016, 08:03:57 AM
First of all, I am very impressed with Q10 Pro Gigabit Ethernet performance. I am getting 938 Mbits/s from iPerf3 .  2.4GHz performs as it should be too at 46 Mbits/s. However, 5GHz AC Wi-Fi has poor result at 71 Mbits/s (connected at 433 Mbps). Just wondering, is this limited by Android 7.0 firmware or Q10 Pro hardware itself? Please advise. Thanks.  :)

How are you testing speed?

It's likely that you've hit a bottleneck elsewhere in Q10 Pro hardware / software, possibly the Samba server or the storage on Q10 Pro (fastest place to copy to will be Q10 Pro internal storage).

Using iPerf3 here.  Pure network bandwidth testing and does not touch any storage or software.

~ 71 Mbps is not that bad for AC wifi.

True for long distance. But the test was run just beside my router.  Most of my AC devices are getting 190 Mbits/s. I was hoping that the slowness is caused by software which can be improved with newer firmware.

Hard to say.  Have you tested Android 5.1 FW?

What I have wrong?
PC:
Connect with HiMedia WiFI 5Ghz - speed connect 433,3 Mb
I instaled samba 1.0.1 and patch  on HiMedia - i choosed Instal i wrote local IP for HiMedia ( 192.168.1.xxx ).
I copy file 8GB with computer fo HiMedia - max speed 10MB/s  time copy about 20 minuts

Nope, mine comes with Android 7.0 pre-installed.

Seem like AC WiFi limitation itself. Check this post - http://www.futeko.com/newforum/index.php?topic=1502.0

??? Wlan AC = 433Mbit MINUMUM! Even my mobile (cell) phones capable of WlanAC do connect @mhz 433Mhz

That's theoretical maximum connection speed. You won't get that maximum on any device.

10MB/s is ~ 80Mbps, which is not too bad for AC wifi.

You'll never get the theoretical maximum wifi connection speed on any device.

The numer of antennas and the router technology also has a big impact on Wifi speed.
I went from an apple airport giving 80Mbps on my ipad pro via ookla speed test to 220 Mbps with the same test using a portal router with fastlanes. This is my max internet connection speed so it may go higher if I had the bandwidth!

An update on the latest 2.0.1 firmware. iPerf3 result shows that Wi-Fi AC performance indeed improved although still not yet reach 200 Mbps but more than double based on previous result. Keep the good work, HiMedia.  ;D

Not bad results for 433 Mbps WiFi like HiMedia use.

I have a 100/50 net connection.

I get the -almost- maximum 98/47 out of the 5GHz band with Q10 Pro.

Tho' on the 2.4GHz band isn't that great, only 47/47. ->And it looks "funny", cause it only affects the download speed, and precisely "cutted in the middle". Been repeated the test many times, and get always nearly same results. Looks like some hardware/software limitation, can't be accidental, nor dependent from the "Wi-Fi range" circumstances. Still didn't try to figure out if it's just the Box's side or it's the router... ???

You are getting the best result on 2.4GHz already as that's the maximum hardware limitation.

Is still can't get what limitation?! Limitation of the 2.4GHz Wi-Fi standard?! I have an ac Router...

Didn't tried it through local network tho', but I guess I would get the theoretical max out from the 5GHz, but the 2.4GHz dowstream perfomance is annoying me (still not bad, but it's definitely artificialy limited)...

Yes, limitation of 2.4GHz at 72 Mbps 802.11n. In real world, you will get around 50 Mbps transfer rate. 

For 5 GHz 802.11ac, you can get 433 Mbps. As usual, actual transfer rate is much lower around 200+ Mbps.

Local 1GB network can reach up to 938 Mbps. More info @ my HiMedia Q10 Pro Review (http://www.jayceooi.com/himedia-q10-pro-android-tv-box-review/)

Since when do they advertize WlanAC? I do KNOW and REMEMBER there was WlanN advertized back then, when I bought the device.
Good for us and the the iPerf values are not totally theoretical. That would make the Q10pro able to stream 4K at decent bitrates via Wlan.
I do prefer LAN at any time hands down.

But good to know I could.

Thanks for testing and letting us know!
