HI everyone,

 

It's a pleasure to join this community and thank you all for your help in advance.

 

I recently installed 3 Deco X10 devices and I would appreciate your help on the following Wi-fi performance-related issue:

 

I have a Fiber set-up at home (1Gbit), with the fiber connection running from the ONT box to a Fritzbox 7590 router (Wifi turned-off). Fiber connection has been checked with the telecom provider thoroughly.

I have set-up a Main Deco X10 unit connected to the modem above, which then connects to a switch, D-link DGS-1016d (as per recommended set-up)

I have structured cabling in the house with cat 5e cables running to every room in the house (typical patch panel/switch network set-up)

I then have a Deco X10 in the Living Room and one more in the 2nd floor, connected via ethernet cable.

All connections use Cat 5e or 6 cable.

All Decos are set in AP Mode and appear well-connected in the app with the ethernet backhaul symbol. "Flow Control" is not checked on the Decos (disabled by connecting to the Deco X10 directly). I have not observed any stability or other disconnect issues at all.

 

I have run speed tests at every conceivable point in the network, at the router, on the switch, at each room wall ethernet port and at the Decos themselves by plugging in directly a pc with a gigabit lan connection (for example on the main Deco while it is connected to the router). At each and every one of these points my speed test shows close to 1Gb speeds (perhaps 980 Mb or so). I tried this on each and every other Deco as well.

 

But when I connect a device to the Deco Wi-Fi nework,the speed tests show significant drop in download speeds, something like 500 Mbps or sometimes at 400-450 Mbps.

I have tried switching Deco units, I have tried changing cables and I have checked that the device that I use for the speed tests supports the latest wifi-standard.

 

Is this drop in performance justified? I don't expect a 1 Gbit Wifi signal just because that's my rated ISP fiber speed but to me it looks like something is off here.

I would expect a loss but this sounds excessive.

 

My only 2 other options that I have not tried is a) try another swicth or b) try another router. By I don't see the reason for this as I see that my ethernet network performance is where it should be at every critical entwork point. Unless I am missing a setting somewhere?

 

Any ideas would be appreciated.

 

Thank you
