AX50/AX3000 : Slow upload speeds in AC, AX modes @5GHz
I noticed that the actual upload speeds with my router AX50/AX3000 appear to be slower to what I could get with my RE650 (used separately in AP mode), except for the 9260NGW in AC mode at 80MHz.
Here're the speeds I measured with iperf3 on an HP Elitebook 820G3 laptop running Windows 10 64bits 1909 with 2 different cards at 5GHz (both with the latest intel driver) on the power supply (max peformance parameter).
NB : the laptop was about 3.5m away from the router, without any obstacles
when the laptop is connected to the AX50 router with a cable I get the following actual speeds : 930Mbps (download), 950Mbps (upload)
|Wi-Fi card - connection mode (Router)||Download (Mbps)||Upload (Mbps)|
|9260NGW - AC 80 MHz (TP-Link RE650)||530||610|
|AX200NGW - AC 80 MHz (TP-Link RE650)||650||650|
|9260NGW - AC 80 MHz (TP-Link AX50)||625||590|
|AX200NGW - AC 80 MHz (TP-Link AX50)||660||400|
|AX200NGW - AX 80 MHz (TP-Link AX50)||680||400|
|9260NGW - AC 160 MHz (TP-Link AX50)||730||300*|
|AX200NGW - AC 160 MHz (TP-Link AX50)||700||250*|
|AX200NGW - AX 160 MHz (TP-Link AX50)||840||250|
(*) in AC 160MHz mode, sometimes the upload results are much lower than this (the transmission speed drops to 0 Mbps...)
What do you think of that ?
