Wifi speed on Galaxy A8

[Simon771]

I recently bought new RT-AC1200G+ router from ASUS, which advertise combined speed of 2,4GHz and 5GHz to be 1200Mbps.

Since Galaxy A8 2018 can only use one frequency at the same time, it means it should be limited to only 5GHz, which is around 870Mbps on this router.

But I did few tests, and I can't get it to work on anything higher than 230Mbps on my local network.

 

Does anyone know what's bottlenecking me? Test was done with some android app that can measure connection between host (my PC) and my mobile phone. Everything is connected with Cat 6A cables and it does have 1Gbps on my PC.

Any idea why I can't get it over 230Mbps? Could it be my phone? Then again I can't find any info about wifi max speed on this phone … Only that it supports AC.

You take your Mbps, and divide that by 8 to get MBps. 230 MegaBITS divided by 8 = 28.75 MegaBYTES. You should see speeds of around 30 MegaBYTES on your phone.

What's the difference?

 

Anyways, it's "UP TO 867 Mbps", not "867 Mbps"

From a quick Google it seems the A8 2018 is still only a SISO device which means at best its going to get a link speed of around 440Mbit.  Considering its not unusual on WiFi for the real-world speed to be half the link speed, you are pretty much in the ballpark there.

Oh yeah that makes more sense now … I do see around 28MB/s speed most of the time.

That will have to do for 4K video streaming

Considering 4K Blurays top out at 128Mbit (and that's not really needed until a new HDMI specification comes out to support 4K 256fps or 8K 64fps), I think you're fine.
