Hi! Yes, wiring the decos will provide each of the deco with what the switch is capable of and mostly it will be at least 1Gbps and hence there will be no much reduction in wireless speeds. Moreover the decos or any other models of mesh devices will still be in mesh configuration and hence fast roaming, smooth handover will still be there.... Some houses/buildings it is easy to do new wiring but many places it may not be possible to do so..... I too have 5 decos but connected via WiFi only as I have to hack the walls for new wiring. I still get 100 Mbps at the last deco which is two hops away from the main deco...... My internet speed is now limited to 500 Mbps due to the prototype 1.6 firmware....hahaha

Correct, best to have all deco wired to have the best wireless coverage. 

I have 5 deco m9+ to cover my house and backyard and having no issues while over 50 devices are connected.

  @MorrisAGE 

Thank you for the info, much appreciated.

My first deco connect to managed switch.

I have 1000/200 from my ISP, my wired iMac gets 940/230 on speed test. It's everything ok, also nat/port forwarding.

  @Wizman 

It is how the system works. For every hop, there will be a speed reduction of 50%. The back haul 5GHz channel (the second 5GHz) is supposed to mimic the wired back haul but I think the decos still use the other 2 channels (2.4GHz and 5GHz) for pulling data from the main deco. A wired Ethernet back haul will not produce this drop in speed.

Thanks for your response.  For me, router to first deco unit is wired but the other two are wireless.  But i see a big drop from the first unit.

I'll consider and think about wired set up if doable for me.  Thanks.

Hi,

I don't have your problem. I have my m9 plus wired.

I have a lot (60) of IOT devices, plus home server, phones, etc

Wi-Fi test

My main concern is the initial 500mbps from the service provider becomes 200mbps only after passing through the first deco then it further reduces down the series of access point.

Is this normal?  How about other mesh brands? Do they reduce wifi also by that much?

I am open to recommendations which are a reliable mesh brands.  Thank you.

  @David-TP 

Thank you. Network is better now.

  @rekeen01 probably Tp-link will release 1.6 version with all the bugs that this forum found.
