Set your 5GHz to run at 80MHz. Not 20MHz, not 40MHz, not auto, not 20/40/80MHz but instead set it to 80MHz only. Don't ask me how, read the manual of your router
Also, if you can afford to pay UniFi 800Mb/s, you can afford to buy a better router
All stock routers from TM/Maxis/Time is crap

Get at least ASUS RT-AC66U B1
Like you, I'm also using UniFi 800Mb/s. I can get 600Mb/s on ASUS RT-AC68U, RT-AC86U & GT-AC5300. RT-AC66U B1 is basically the same as RT-AC68U so you should be able to get at 600Mb/s on WiFi as well
Below is a screenshot of the Speedtest on WiFi



No
You can only reach 300Mb/s on 2.4GHz if your WiFi receiver is 3x3 & running at 40Mhz

Most devices only supports 2x2 & that limits you to 150Mb/s which translate to actual speed of 90 ~ 100Mb/s

1. If you want full 300Mb/s, you need 5GHz running at 80MHz
2. Dump that WR1043ND. That's a very old router. My suggestion to at least get an ASUS RT-AC66U B1

why so confusing??? Make life simple la... why we cant get full 500mbps as we subscribe that speed??? hmm..

set my 5Ghz already to 80Mhz... channel leh?? select auto?

What's confusing about that?
The ISP is actually giving you the speed that you subscribed, but only on Ethernet cable. No ISP in the world can give you 100% of the speed that you subscribed on WiFi because that is impossible as it depends on several factors

Let's say the ISP has already configured the best wireless settings for you, when they test on their phone that supports wireless AC 2x2, they can get full 500Mb/s
But the customer is using a cap ayam phone that only supports Wireless N 1x1 that only maxed out at 72Mb/s, is that the ISP fault?
I use chap korea branded phone wo...
That one you need to figure out yourself
You need to find out which channel is less congested then use that channel

wah lau bro how to find out leh??? man tau all this things??


For ASUS routers, you can just use the built-in "Wi-Fi Radar" tool to find out which channel is best for you
Not sure about other brands, you'll have to figure it out by yourself

Here, let me help you:

Google very confusing. Diff ppl tell diff things who to believe?

Hi guys,
Need advice on my network setup.
I'm subscribed to 500mb Unifi plan using Deco M9.
Using macbook pro 13, I can achieve ~250mb with line of sight.
Is this the max I can get with my current setup?
Can i do anything to achieve higher speeds over wifi?

People say TM router is crap but I have a different experience.

I have 800Mpbs but could never get that with AC1200 supplied by TM, around 400Mpbs. So I went out to get a Asus AC68 and CAT6 cable to hook up to my desktop computer. I still get the same 400Mbps on my desktop

I complained to TM and their technician came. They took out their beat up TM router and getting 600 to 700 Mpbs instead. So I can't complain any more.

Then one day, my AC68 refuses to connect for whatever reason so I took out the TM AC1200 again and hook up. Sure enough, I am getting the same speed of 400 Mpbs of my Asus AC68

BTW, I didn't do any special setting. I just hook up, log into my account and use both routers. May be I need to do some special setting on my Asus that I didn't know about.

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, I would like to recommend you to change router this stock router is unable to handle the speed that you're using.

I would like recommend you this router ( ASUS AC86U or ASUS ROG GT-AC2900.

Thanks.

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.

I'm an agent for TIME. C1200 is very old and have a lot of issues and is replaced with TP-Link EC230.

This is due to router problem. Your receiving devices specs looks fine and able to support 500Mbps.
The router is preventing from you getting full speed via Wi-Fi.

What's your LAN Speed? 500Mbps?

Thanks.

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.

Hello, for the C1200 normally can get up to 250 via Wi-Fi.
If you are getting only 250 even near the router means you need to change the router.

I'm using TP-Link Archer C9 AC1900. I'm able to get 400-500Mbps near the router.
In the room around 100 - 200. Changing to Wireless AX Router and Wireless AX Adapter will solve this issues.
Supposely that C1200 is suitable up to 300Mbps only.
That's the reason that it can't achieve.
A few of the forumers here change to a new router and will solve the issues.
I have C1200 with me but it is totally worse than my own router ( Archer C9 ).
Even for 5GHz from C1200 getting lower speeds than my own router.

Thanks.

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
