Hey

I have an EAP245 and done some iperf tests previously and got around the 370 range, just ran then now and got 457 average, but the air is pretty quiet today with no other rel traffic going on.   This is on a 2x wifi card (intel AC-8265) on 5GHZ channel 40 to a 1GB LAN connected desktop.     Range is approx 6m from AP through a stud wall

Hope that helps!

@Philbert 

Can you post exact perf3 command which you used

@Egis 

Certainly

On Server  :   iperf3.exe –s

On Client :   iperf3 –c 192.168.x.x –w 2m –t 30s –i 1s

@Philbert 

Best 336 Mbits/sec on not busy AP.... 

@Philbert 

Testing with 2 different phones 2x2 clients both. Dont have laptop with good wifi card... 

@Egis 

Hey.. Just realised that you mentioned a sony phone in the first post so i have ran IPerf3 on my mobile connected to the same AP as before.   

Only difference is my Phone is 1x aerial so its "connected" at ~390mbps.... iperf comes in at 150mbps, which I would expect for 1x , double that for 2x... sounds plausable

Being honest, with the results you are getting on a mobile device.. this isn't unexpected and personally I would say well within expectations.  

IF you check this video out here, this chap review the latest Uniquiti Nano Wifi6 which is a more expensive device.. hes getting the same results as you     https://www.youtube.com/watch?v=f5WUifimRcE

Honestly.. I dont see anything wrong here with your results.  In your scenario and setup i would expect 300 to 350 tops.. Sorry..

iperf3  mobile to LAN

Thanks for explanation, will try eap660HD if get for good price. 

Hi @Egis,

Using a variety of internet speed tests (I have Gigabit FIOS -- FTTH) such as Ookla SpeedTest, SpeedSmart, and Fast.com, I routinely see application-level speeds of 350-550 Mbit/sec DL & UL on my EAP225V3's and EAP245V3's when testing with a variety of 2x2 clients over 5.8GHz (80 MHz).

iPerf speeds are generally ~15-30% higher.
