hello all,
I had just subscript maxis home fiber optic 300mbps. The wifi 5Gzh is good with speed of 200 to 220 mbps. But the 2.4gzh is only between 30-50 mbps. (Tested the speed in the same manner, environment and device). How can I increase the speed because most of my devices at home like cctv, smart home, printer etc uses wifi 2.4gzh? I hv tried tweeking the channel to 1, 6 & 11 but not much diff in speed. Thanks

if you using default maxis wireless router you need to get a better 1 .

you should be getting 300mbps on 5G
and about 100 to 150 mbps on 2.4G

2.4ghz can’t get high speed like 300mbps due to congestion and interference, you’ll need to use 5GHZ for it or Run Ethernet cable to it

You might want to replace the stock maxis router as well.... follow the guide on choosing one here https://forum.lowyat.net/topic/4658096

"How can I increase the speed for 2.4ghz?"
you can't

simply move ur router closer to them for 5ghz wifi
(if ur device don't support 5ghz, then ethernet)

and it's GHZ not GZH

Click on the link on my signature and read ALL the green text. 2.4GHz is congested and full of interference. There is no way around it.

Getting a better router won't help. It is what it is.

Upgrade all your devices to support 5.0GHz instead.

devices at home like cctv, smart home, printer etc = use LAN Cable
not suitable wifi its no good

my PC and CCTV and roku ultra all using LAN Cable
mobile phone using wifi 2.4ghz strong signal speed below 70-80mbps enough mobile phone not imported high speed so i don't care

my PC Desktop connected LAN Cable full speed

i using unifi my own ASUS RT-AC68U Router power full then free router tp link poor

Speed test @ 2.4GHz


To squeeze out Maxis Route, do this settings:
Mode: 11n only (old standard b/g with n cause overhead, no need b/g in 2020)
Channel: 3 (going to use double width, 3 + 6)
Channel Width: 40MHz (More wider = more speed)
My old Asus DSL-AC52U can handle 2.4GHz @ 108Mbps, but can't handle 255 TCP/IP sessions, Stock Maxis can handle 4096 TCP/IP sessions, quite fast BT download

Speed test @ 5GHz


To squeeze out Maxis Route, do this settings:
Mode: 11ac only (11a is old support only 20MHz & useless in 2020, 11n is kind rush and fill gap & support 40MHz, 11ac is better & support 80MHz)
Channel: 36 (going to use triple width)
Channel Width: 80MHz (More wider = more speed)

Please, stop using 40MHz in 2.4G, and don’t use any channels other than 1,6,11, be a considered neighbor, all those CCTV, smart home and printer don’t actually require any speed higher than 5mbps, plus they r sleeping most of the time. Also, it will cause more interference due to wider band, u r interrupting ur neighbors so do them, urs n their Wi-Fi will become unstable.

From the results posted by the author, I can tell his phone is only 1x1 antenna, it’s quite normal for 2.4G to get 30~50mbps, if 2x2 it will become 60~80mbps, really ok for an 2.4G devices, so don’t worry about it.

To design a good Wi-Fi in home, 1st u must have a clear idea, 2.4GHz is for compatibility and coverage, for those home devices which doesn’t require high speed, so stability and usability is the target. Any devices that require high speed, they should go for 5GHz.

2.4GHz, the highest I can get with 2x2 Intel 9260 card is 130 Mbps. That's when neighbours not yet moved in.

This is my 2.4 GHz congestion (my SSID is finalfantasy). Mine is a landed property.

I didn't realize I have so many neighbours.

But the 5 GHz spectrum is pretty clear.

Your 2.4G is a big trouble for your neighbors and they are interrupting you too, bear in mind that not only router send signal, but also clients, and it's not showing in many wifi tools, not that simple, I will choose channel 11 with 20MHz based on this graph.

Channel 100 for 5G is almost always clear in Malaysia, but I will choose channel 52 since it's clear too based on the graph, due to wifi is always 2 ways to do, router to client and also client to router, not many clients supported channel 100 in Malaysia, more important is when we design a wifi, we have to consider the tx power of our clients too, for example my phone:




As you can see, channel 52 is 168mW and channel 100 is 171mW, almost same but due to lower frequency, my phone is actually doing better in channel 52 and bigger coverage since now my client is able to respond in farther side. Why not channel 149 since it does 275mW? It's much higher frequency so it requires higher tx power means it drains my battery, also it's not recommended to use channel 149/153 for Apple devices according to Cisco, they are actually the one who worked together with Apple for wifi design, they knows it better. You may check you clients tx power for better understanding how to bring the best out of them.

How is your 2.4GHz performance?

I am on Unifi 300MHz Turbo Upgrade plan.

Here are my Speedtest results for 2.4Ghz and 5Ghz (both tested on Wifi)

I am using a Netgear dual band USB adapter on a Windows desktop PC.



Attached thumbnail(s)

I am also on Turbo 300Mbps but my speedtest results are nowhere near yours.

You must have good networking hardware.

I purposely make 40MHz wide, just mess with neighborhood Wi-Fi + active LoS communication
most of my device run on 5GHz

2.4GHz is hardly to get more than 100mbps. Mostly floating around 80~90mbps for the best results what I can get. It just good for wider coverage only. My suggestion is switch off all your routers 2.4GHz and turn 5GHz into mesh.

Get a set of mesh router such like TP-Link Deco M9 Plus (RM1,269)
https://shopee.com.my/TP-LINK-Deco-M9-Plus-...0984.1750500485

or Aimesh for Asus router.

So now you can totally switch off the 2.4GHz channel, then use your mesh wifi set to spread out the 5GHz wifi around every corners of your house.

Don't ask me why so expensive because last time people blame that Malaysia internet is slow and expensive. When internet slow, our routers requirement is low. That's why you can't feel the different between 2.4GHz and 5GHz. When internet is fast (thanks to our minister), Unifi and Maxis been turboed up to 800mbps. Everybody start to buy expensive routers, need to build mesh system for big family. Budget for more than RM1,000, it's normal.

Smart home IoT devices do not support 5ghz at the moment

can stay 2.4GHz turn on for smart home IoT.
