Hi,

This is what i have,

Time 500mbps
router: TP-Link c1200
modem: Huawei EchoLife HG8240H

Laptop: Intel® Dual Band Wireless-AC 8265 (2 x 2)
PC: TP-Link Archer T4U USB Wifi Adapter (2 antenna and support MU-MIMO, 2x2 correct me if im wrong) connected to USB3 port
phone: note 9 ("enhanced 4 x 4")

all support 802.11ac and i connect my devices to the 5ghz band.
speedtest using a few different tools such as ookla speedtest all gave me similar results pretty consistently.
DL: ~250mbps UL: 300 - 400mbps
all settings at default/auto

Also tried manually configured afew things as suggested above such as setting channel width to 80mhz, change channel and so on

if i specify cahnnel width to 20Mhz, the speed does go down, so it indeed affect the speed.
after changed to 20mhz: DL: ~150mbps UL: ~90mbps

Am i missing anything? (i actually created ticket to Time to ask for technician to check, pending respond)

Hi you work with Time? actual performance vs spec so much difference? I'm sad. Anyway i have contacted Time and waiting for the technician to call, i'll get them to confirm the issue first.

Thanks for the info.

Time technician called me and this is what he said
it's normal to not reach the max 500 mpbs for wifi and 250 mbps is normal although the router support higher than that.
So i asked why my friend same router can reach 490mbps , he said no guarantee one and 250 is acceptable(not to me) and i only need to worry if LAN cannot reach that speed.
Currently don't have LAN cable cannot test that, will get a cable to test

hate the fact that the router differ so much interms of actual performance vs spec(and my friend does get 590mbps with same router). I understand the words "up to" but still...haha thanks for the info.
may be the wifi can run that speed but cpu and ram of the router cannot handle?
if my LAN gets near 500 then i will get another router. Thanks again

i clarified with him again, he is using ec230-g1 connected to the modem then extend it with the deco m5.
Just now when he test again the speed, connected to the ec230-g1 he only get 50mbps lol
connected to the deco m5 he gets 230 mbps, seems like his connection is worse than mine, not sure if he got connected to the right band or not.
the 490 mbps one he got it when he first setup his mesh router, he mentioned may be because that time only himself was connected.

thanks for the video, so basically my(no wall, within 5 m) speed is similar to his with the wall in between.

could it be that Huawei EchoLife HG8240H the bottleneck?

may i know which router?

not cheap, may be later find one cheaper one aha

I tested lan cable can go up to 450mbps(is that normal? thought it should near 500 like 480+), so like what you said, really the router wifi capability cannot la. Today testa bit better, able to get up to 300mbps depending on the server i chose.
later got budget change to a better router.

need to google how to do that, by the way is my router due to the lacking of "MU-MIMO" thing?

yup you can pm me i will try later, thanks

from the original post

"2x2 means 2 transmit and 2 receive.
MIMO (multiple in/multiple out) means the wifi can receive,send more than one wifi stream at the same time. Everything is MIMO now.
streams are sometimes called chains. Some people use the term antenna. Not wrong. One stream needs one antenna to transmit. Then you look at the C1200 which is 2x2 but it has 3 antennas. How leh? That one I explain later."

i dont see the explanation after that, can some one help point me to it?

I c, thank you! i assume the chipset on that router support ya
