Model: Deco M9 Plus  
Hardware Version: V1
Firmware Version: 1.2.11 Build 20190926 Rel. 55727

So i ordered the Deco M9 Plus ( set of 3 ) yesterday, got it today. Hooked it up and noticed a nice fast network. However..

 

There are ping spikes round about every 10 seconds. I am sure this has to do with the M9 wifi, because when i connect my Desktop to the nearest Deco by UTP cable i have a perfect connection.

 

My setup is also very simple :

- I have a 1000/1000Mbps fiber connection in my Genexis Platinum-7840. Wifi is disabled on that router.

- I have 3 Deco M9 Plus. The 1st one is connected by UTP to the Genexis. The 2nd and 3rd are added by using the app. All of them about 5 - 8 meters apart.

 

Also between my Desktop and the 1st deco there is about 4 meters with a plasterboard wall in between, so that can't be an issue either.

 

Here is a screenshot when i'm connected to the Deco WiFi. Very obvious spikes.

 

 

And after this, i connected my desktop wired to the Deco. Extremely stable connection

 

 

My IP / gateway : 

 

 

It seems to me that this proves there is no problem with my internet connection. 

Also it proves that the problem is caused by the WiFi of the M9, since the wired connection to the M9 works perfectly.

 

I'd like some help, since i ordered this because of the many good reviews and it now turns out i should have read more. Because after googling this issue i found many topics that are describing this problem. 

 

I'm disappointed by this. I don't want to spend my friday evening writing topics about ping spikes. I expect hardware i paid a BUNCH of money for to work properly.

Figured it out.

 

If anyone else is having this issue it is because your WiFi network card in your desktop automatically keeps looking for the best WiFi network. In many cases ( like in mine ) the quality of the different Deco's ( best reception ) is similar, which will cause your WiFi network card to switch every time.

 

Fix 1 : There is one way you can fix this in windows :

 

In your windows cmd, type in

netsh wlan show settings

and one of the last things might say

Auto configuration logic is enabled on interface "Wireless Network Connection"

if that's the case, then type in

netsh wlan set autoconfig enabled=no interface="Wireless Network Connection"

It should respond with

Auto configuration has been disabled on interface "Wireless Network Connection".

If it doesn't, then you might have mistyped your interface=" part. Check in your adapter settings, you might have Wireless Network Connection 2 or 3 etc.

This will definitely stop your wireless card from searching for nearby networks and updating your signal quality when you're not asking it to- which is what is causing the spikes.

You will need to turn it back on if you disconnect or need to be able to find nearby networks again. 

 

Fix 2 : The other obvious solution is to make sure that your desktop always has 1 Deco that gives it the best network, so either place it closer to your desktop. Or place the other Deco it switches to further away.

 

Hope this helps people with the same problem.

I see these spikes every 8 to 12 seconds. my whole internetconnection freezes.

 

If i connect through cable or an other router i dont have this problem.

So i wonder if this is a problem of the M9. i have the version 2 and i downloaded the firmware 1.2.13, but it did not help. 

My wifi is useless right now on my laptop. I took a long cable and plugged it in to properly work.

 

I hope someone has the same issues as i do and have a solution for me.

I also checked the internet and saw some similar issues but nothing worked

I also tried to connect through an usb wifi adapter, but still the same

 

I have 2 questions:

 

Is this a problem of windows 10 or

Is there still something not correct in the TP-link m9 V2?

 

please help,

 

Dave

Constantly random spikes to 150+ ms with no other big bandwidth consumers in the network.

Even when connecting a super short cable directly to the main deco gives me this problem but like 10 ms less only... still horrible. (not above ping test)

It's almost like the WiFi is fine...but the (main) deco takes too long to proces the packets every now and then.

Back to back connected.
