Just set up a couple of these units and am disappointed in the Wi-Fi speeds.

Just want to know if this is a Wi-Fi limitation or something going wrong.

LINE speed according to the Deco app is 914.2Mbps/475.7Mbps

A laptop plugged in via Ethernet is reporting around 565Mbps/402Mbps on Speed Test and 530Mbps/410Mbps on Fast.com

A different laptop over Wi-Fi via the X20 Mesh network (2 unit, Wi-Fi backhaul) is 85Mbps/89Mbps on Speed Test.

An iPhone XS Max and iPhone SE (2020) on Speed Test are reporting 91Mbps/90Mbps and 81Mbps/45Mbps respectively.

Are these typical Wi-Fi results??

I have a Fritzbox 7490 Mesh network set up elsewhere with an ethernet backhaul and that can hit 306/260 on the iPhone XS Max (I believe according to Google that this has 802.11ac Wi‑Fi 5 with 4x4 MIMO). On that network the iPhone SE (2020) which I believe has 802.11ax WiFi 6 with 2x2 MIMO hit 140Mbps/310Mbps (not sure why the upload is so much better than the down?).

Any insight into all of this would be great thanks!!

Edit: Going to see if I can turn off 2.4GHz network and see if this helps at all - however is it wise to keep 2.4GHz on? I'm not sure if all my devices support 5GHz.

I have not looked at the X20 specifically but unless you have a dedicated back haul radio mesh units are always going to lose speed if they have to receive and transmit on the same radio

Laptops running windows will never pull a gigabit speed even wired

Any views expressed on these forums are my own and don't necessarily reflect those of my employer.

Hey there.

If the Decos aren't backhauled via Ethernet that's really going to limit things.

The other thing to note is that you have to have the hardware to actually pull 1 gig. Your laptop speeds only pulling just under 600 sounds like you're testing on a web browser or not having powerful hardware to saturate that 1gbps link.

The idea around the Super WiFi (the X20 Decos and any other mesh unit) is to get it into corners it a single CPE can't reach and it's certainly doing that but if you want to be as fast it can go absolutely cable these units.

I’m also trying to get my wifi into all the corners of my house.

I live in an old farmhouse that about 20 years ago we wired with CAT6 cabling back to a CISCO 16 port giga switch.

We could only get ADSL here, and we used Spark with their Huawei router, provided pretty good coverage but there was always wifi black spots.

We’ve just installed Starlink and it works great, also plugged into the CICSO and I use some devices on Ethernet no problem - I now want to fix my wifi coverage.

Can anyone recommend devices I could use (on an Ethernet backhaul) to extend my wifi throughout the house - keeping the same SSID to allow for seamless roaming? I imagine there may be two additional extender devices required on opposite sides of the house.

Thanks! Have often used GZ when looking for answers, this is my first post. 🙂

@PukeStar I suggest you create a new topic for this question as it's particular to your case.

Off the bat, I'd say suggestions will be around using a mesh system or something similar. Once you create a new topic I think you should tag @michaelmurfy who might give you a couple of ideas.

It sounds like you are also testing the WiFi over a 2.4GHz Network as well. Does the X20 give the option for a seperate 5GHz network? Can you turn off 2.4GHz?

If I test (on my 300/100 connection) at home over 2.4GHz, I get similar results to that. If I connect to the 5GHz network, I get line speeds to an iPhone, and my laptop. I have two seperate SSIDs (one for 5GHz, the other for the 2.4).
