Model: Deco M9 Plus  
Hardware Version:
Firmware Version: 1.2.8

Hi All,

 

I'm guessing this question has been asked before but can't seem to find any real answer to the problem (or anything I have not tried yet). I've recently bought the Deco M9 Triple pack and have finally got a stable Wifi connection throughout the entire house BUT as an IT specialist things did seem off during speedtests and I just can't put my finger on it.

 

My optic fibre internet connection is 1000mbs/1000mbs which in practice comes done to around 920/940 (yes really) and a ping of around 1ms. My speeds on wifi on the other hand are maxed out around 200mbs/160mbs on any device (macbook pro 2013, iPhone x, LG television) on 5ghz and 40/10 on 2,4ghz which dissapoints me quite allot. Houses in my neighbourhood are well isolated and mainly made of concrete (reason I need more then just my providers FritzBox) and thus I only have interference from my direct neighbours (that own a google mesh wifi) they do seem to be on the same channel as my 5ghz band but since I can't change that it can't be helped.

 

Reception to the devices are great and mentioned speeds are at point blank from the M9 (though it's hard to tell to which I'm connected but let's assume it's the one closest to my position).

 

My setup is as follows:

 

  • Fritz!Box
    • (LAN) Deco M9 (primary)
      • TP-link 1000mbit 5 port switch LAN
        • (LAN) Deco M9 (2)
      • (WIFI backhaul) Deco M9 (3)

 

Now I have no idea of the second M9 connects through the lan line or is still using backhaul and as mentioned I have no idea to which my current devices is connected during testing but removing the secondary devices gives me no better speed so I can assume it's already going wrong at the primary M9.

 

Speedtests on the Primary M9 give me around 690/840 BUT i'm used to these numbers on a single server basis and am not sure which servers they use for the tests so they might be capped out at their end. When I connect to the primary M9 directly with a lan cable I get 900/900-ish so that seems to be in order.

 

There are about 5 devices connected throughout the entire network (other devices connect to the fritzbox wifi at 2,4ghz but all mentioned speeds above are with wifi totally disabled on the fritzbox). The devices are: LG TV, Google home (2x), Macbook, Iphone X. 

 

Knowing is half the battle but since the app doesn't give any advanced information I feel a bit lost. Oh everything is up to date.

 

Hope anyone can help me out with this, some tips would be great. Tonight I'll try everything again and will also show some stuff from 'Wifi explorer' (mac App) and speedtests by ookla

According to your description, the speed on LAN  connection seems good. We will do further trouble shootings on the Wi-Fi connection. 

Please connect only one device to the Wi-Fi network to test the speed. Please also check the link speed for Wi-Fi connectoin. Here are some instructions for you to check the link speed.

For comparison test, please check the speed on different wireless devices and provide the test results like the following example:

iPhoneX, 5GHz, speed test: 200Mbps/100Mbps, link speed 433Mbps.

Hi Kevin_Z,

 

Thank you for the reply.

 

I've decided to reset 'everything' within my network (Fritzbox, Deco's, etc) and now am getting better speeds of around 400-500MBPS in some places. Now the only thing I have to figure out is why during speedtests though the Deco app I get 600/980 (down/up) speeds whilst my internet should be 1000/1000 (let's say 900/900 including overhead), I will have to do a speedtest directly through the fritzbox to see if those numbers are better.

 

I will also check what is mentioned in the instructions and will come back to you. 

 

I've got a feeling your product/app is missing the following:

  • Little bit more detail of the decos network (how are the Deco kits getting their connection)
  • See which devices are connect to a specific Deco
  • Speed test between decos (when using backhaul) so you can see if placing it elsewhere will help overal performance
  • Speed test from the device to the deco (is the wifi good enough or is it my internet connection)
  • Disable wifi backhaul if not required in the network (all my decos are no wired), this will free the 5ghz band a bit more and even allow for other channels on the original band

 

 

Hoping to get better figures the following days, for now have a great day!

Please take your time to test the speed directly through your Fritzbox and get back if there is any further issue. 

 

As for your kindly feedbacks about the product feature, we will feed back to our R&D department and then they will work on and evaluate the feasibility. We appreciate it very much. 

Good day.
