ping your router ip and google dns ip(8.8.8.8) when your are facing issue.
And if the result is normal,then the problem normally not at your end or not within your home.

But if the latency to your router ip is abnormal,then u might need to check your network.

Why would you replace that router with the old TPLINK C1200 which is known to overheat and have problems?

Spike  are usually overheat related

unless you having plan to upgrade the plan speed later, AX72 is more than enough

I concur AX72 is more then enough but AX73 for future

Pro for Asus would be very long firmware support
(you get what you pay for)
TPLink... Consider AX73

get latest AX73 future
AX72 IS too old

ASUS TUF-AX4200 for a simple reason. The 2.0GHz Quad Core CPU.

It's a huge difference in overall smoothness. Loaded latency / bufferbloat is more important than raw speed these days.

Since you stay in East Malaysia, you probably have a bigger house.

I will suggest getting a mesh Wi-Fi system. By doing so, you can get more 5GHz coverage for your entire property.

2.4GHz is the culprit of low speed and high ping.

the AX72  can easily provide coverage to your DS house/all rooms  .  but place it  in center of house. high up between ground and first floor.
i have check the rooms signal coverage  and easily get -60dBm  in rooms .  use wifi analyser .

so happen i have a tall glass showcase in center hall  nearly 6 feet. place on top.
anywhere in center of house , midway between ground and 1 st floor is fine. ensure no obstruction to the antennas is best.

there are 6 antenna .  2 x 2.4G  and 4x 5G
pointing /antenna angle placement helps if you want certain room have stronger signal.
counting from left /looking from front of router, antenna  no 1 & 3  are for 2.4G

the only difference between AX72/73  is the cpu used .
and AX72 was release 5 months after AX73 .  year  2021
there was 1 update so far.

my 5 year old router was a Asus AC1300 , now keep as  standby spare.
the asus wifi signals/ -70 dBm  at 1st floor  are weaker cos of walls  but still ok .

use wifi analyzer APP for android phone
get from google store  to measure the wifi signal strength  in the rooms.

MCMC don't care about bufferbloat.

I believe C1200 comes with QoS feature.

Try to set enable the QoS function and limit download speed to 27Mbps. Do the same for the upload speed and limit it to the 90% of actual speed.

Should be able to solve your bufferbloat issue. If still not solved, you need to change a router.

I bought ax72 to replace my ax10 as the coverage did nothing covered all. After 1 week, returnees its for ax73. Never looked back at since. Before was using tm router with 2 tp link mesh. Then replaced with ax10 no more mesh. Overage of my house not full, ax72 didi fiver all, but performance drop the further room. Changes a73. Great. WiFi 6 everywhere.

I just went down this list vs price. Find something affordable at good penetration.
https://networkshardware.com/routers/review...nk-archer-ax73/

After ax10 I can play steam link properly. With ax 73 can play wireless to my phone/laptop from my wired pc. No lag.

Sorry for the typo errors previously. Autocorrect on phone. I actually did considered that but reviews say it doesn't not penetrate that much. Asus router is more towards gaming but when comparing price to tp link for the same class, tp link is more value for money. I did consider the Asus ax86u, but I cannot justify the price and great coverage. I am interested in the parental control, but by the time I need to implement for the kids, maybe it will be Wi-Fi 8 or 9 standard. Also I have opendns for parental controls, if I need it. The ax86u may have greater coverage, but then I don't want it to go into neighbours house, as I then may need to hide SSID to prevent hacking. Also, I need only 4 wired ports maximum for my case, nothing higher. Cctv, pc and NAS. The extra port if I need to wire up my laptop in bedroom to the NAS..

I did a map of the WiFi reception for my entire house to see where the heat place to place the order Wi-Fi router and a 10 M Ethernet cable. I'm satisfied that it covers the perimeter of my house including the tapo cameras outside. Anything higher than AX73 will give me diminishing returns. 2.5gb or 10gb is no use when my unifi is 100mbs. And I backup work and upload data a lot. So any higher broadband package will still give 50 mb upload.

What I will say is that tp link deco mesh is not really that good to expensive for what it is. For the price of a high end mesh, you can get a very high end router without latency problems for gaming. Previously, I bought a pair of E4 deco. I have about 27 connected device, including 2 Wi-Fi cctv, Ethernet cctv, iot, NAS, wired connected gaming pc. The mesh got fried when I do sustain up/dl from pc to NAS. Either dropping connection or connected wifi devices drop and unable to connect again. Like restoring files. My pc can do 2.5gb, nas can do 1gb,fine with me. Wi-Fi speed almost like wired in same room. Furthers room, I get about 90% speed. Of course I enable QoS for both my gaming, hp and laptop. I do steam link as kids watch cartoons on the TV and my pc is setup like a console with steam big picture. One button on off. Exclusively controlled with xbox wireless controllers. If I need to play games away for the TV, I just turn on the pc in the background and go to my laptop/phone to play. I played about 40% uncharted 4 on my phone and laptop.

Using uncharted 4 and steam big picture, Gaming on mesh is unbearable. Gaming on ax10 is ok, if in the same room, if you get the WiFi 6 on the phone. The moment I go to different rooms, I drop the 5ghz for the barley reachable 2.4ghz connection. I only have 1 wifi 6e tablet, but that is my wife's. On my Wi-Fi 6 phone, I can game ok.

I am lucky I started with tp link ax10 and I can see where the problems are. I keep that as a spare as I also fried my unifi dlink wifi 6 router..also due to the NAS transfer. Also, it takes forever for a device to connect WiFi with to the unifi.

Did you limit your upload speed to 90% of your subscribed speed? Still seeing 28.3Mbps on the result. Perhaps you can try to force it lower to 25Mbps.

Bufferbloat is caused by poor congestion management which is generally handled by the router. You can Google for more details. It will be worsen by slow subscribed Internet speed.

That's why I recommended ASUS TUF-AX4200 to you in my first reply as it comes with AdaptiveQoS. It's especially useful for users who subscribed to slower speed.

What I am guiding you now is a hard traffic shapping to deal with the issue. While it can solve the issue, your speed will be 10-20% slower as a result.

my 2 sen .
your latency /ping  is  very high  47ms
if this is on wifi ,  you can try  wired cable direct connect to router test /pc  and test . should get better  lower latency.

i get 4ms  latency  /Ookla  test  from TM msia KL  to house  30km away.  Also can try  https://speedtest.tm.com.my/
on Waveform test  i get  9 ms.

you will get better performance with a new AX router on wifi .  your devices need/can support  AX

the 30Mbps plan you have will be an issue  if you have many people in your house or have many
user devices online .  just 2 video session you already at your  bandwidth limits.

Sadly, that's the norm for Sabah Sarawak.

Most of their International connectivity are routed through the exchanges over here in Semenanjung.

Nothing can be done on the base latency. Only the loaded latency is something that can be solved.

For your scenario, your current router is the culprit due to bad congestion management.

No, I don't hack the walls. Just follow current electrical trunking where available. Where not available, I just use hook and hammer to the wall. Only two places in my house I did need proper drilling. When the ac maintenance people come, I ask them to drill a hole for the wire to pass through.

During MCO, 3 people WFH,, webex/zoom and kids on their device and it was fine. Now only 1 WFH. for my gaming purposes, even if I download games, it does not affect other people streaming their youtube/Netflix.

Change your QoS profile to Work From Home and jump on an actual GMeet call to test it

Bufferbloat is just a test it won’t indicate real world scenario

means  there is nothing wrong with your routers.  !

this test  also say you got  high latency .  the cause need to know why    first  !. .  my guess you got line problems .

try use ping plotter .    download  the app  and  run  ping to  www.google.com
use google dns 8.8.8.8
post the pix. / screen  snip

OUTDATED info, kick it to wireless adapter test first.

I will put my bet on
T9UH wireless adapter

Try using a cable direct to the router, then run bufferfloat testing for temporary testing, if solved, it means better buy a Intel ax2xx to replace the USB wifi adapter.

Based on v2 hardware ver, it is same chipset as mine.

Lucky I got similar chipset, based on my testing, this Realtek hardware got a fault on handing 2.4G + 5G, by disabling 2.4G, I solved the background scanning of 2.4G + 5G take too long time, and cut off 80% of transmit time on 5Ghz.
Yes, it means when someone is transfering over WiFi on same channel, and you got likely 20+ of SSID around you, you are likely get high latency even when it is unloaded testing of latency.

Try install this second latest date driver, but latest branch.
(1030.45, 1030.44 got sync time bug which will disconnect when time changing in forward)
https://www.station-drivers.com/index.php/e...HQL/lang,en-gb/

For update manually, extract by right click on it, then "Extract All"
Copy the path of the extracted folder, then.


Then, to fix the latency issues.

To ensure complete reboot, shut down the computer, unplug your wifi adapter, plug in back, boot your computer.

Try run bufferbloat test again, see the result?

And yes, no USB 2.0 extension please, this likely causing issues, unless you using WD-40 to clean up the golden finger/pins

From my experience, bufferbloat usually caused by ISP rather than router.
My 2 houses are using Citybroadband and Maxis thru Allo backbone, both bufferbloat A/A+. Using cheap/stock ISP router.
While my office using some highend router & cisco switch, 800mbps plan, still B/C only.

Just check your upload speed when doing video conferencing.

Anyway, if you max your upload speed, then your internet gonna suffer. Previously on Streamyx 2Mbps and someone phone or pc kept backing up and it totally renders the internet unusable when the upload is maxed out.

30Mbps is totally fine for a couple devices to stream 1080p but once you hit the download/upload button, everything goes to hell. Why not upgrade your subscription instead?

This was my test on my sister internet(home internet) to combat bufferbloat.

My two cents about your situation, I'm quite certain that your CGNAT region is the one causing bufferbloat issue.

Currently I'm in Johor and my CGNAT gateway is 100.88.191.x, public IP is 60.53.x.x and my bufferbloat on LAN/5GHz AX is both A

My setup for wired LAN for testing is OPNSense VM - 16 Port PoE Switch - TP-Link 8 Port Switch - My PC
For wifi it's OPNSense VM - 16 Port PoE Switch - TP-LINK TL-XAP3007GC

I also have shapers on my OPNSense for the 30Mbps connection

Strongly recommend you contact TM and complain to see if they can reset any gateway or check on their side, CGNAT users can only get a few no matter how many PPPoE connects/disconnects we do

Considering your router currently is already decently high-end, even with QoS it shouldn't be THAT bad
As before I shaped my traffic with OPNSense, my bufferbloat can go up to 200-400+ ms when dl/ul, and can shoot up about 100-200 while unloaded

I installed MT7621AT based router/wifi (<rm200) on my cousin home, under cgnat 30Mbps unifi.On default router..the bufferbloat was very bad.After installing this router with AQM in place with proper wireless channel tuning(mainly 5GHz band,only one device on 2.4GHz which is his air purifier), never ever heard him complained.He had 6 devices connected to the router, 5 devices wireless and 1 pc hardwired( online gaming).Of course, when isp have problems ,no AQM can save you from bad bufferbloat.

Guess op busy working, let him test my workaround(disable 2.4GHz background scanning) on his Realtek Wireless USB adapter first, it is very likely another victim of Realtek.

Seems like mine is worse

Based on your latest test, it looks very healthy now. Glad that my recommendation works for you

Spike is unavoidable, it's normal and shouldn't be disruptive.
