VM Hub 5 WiFi is faster than my Ubiquiti setup

Hi,

I'm hoping someone can help me in optimising my WiFi speed as I'm at a loss as to why my Hub 5 is able to produce better WiFi speeds than my full ubquiti set up.

My current setup has my VM Hub5 in modem only mode feeding my UDM Pro (from the 2.5G port on the hub) with the WAN connection - wired I'm getting the full Gig1 connection speeds so no problem there. From the UDM Pro then have my switch (USW-Pro-48-POE) connect via SFP which is then powering 2 access points in my home - U6 Pro and a Nano HD. 

My access point settings are as follows...

2.4GHz

  • Channel Width: 20
  • Channel: 13
  • Transmit Power: Auto

5GHz

  • Channel Width: 80
  • Channel: 157
  • Transmit Power: Auto
  • Meshing: Off
  • Band Steering: Off

I've ensured the APs are in the least congested channels for my area and im getting an average speed ranging between 350-400Mbps on Fast.com from my iPhone 14 Pro. However, out of sheer curiousity, I decided to test the Hub 5 WiFi and found it was ranging between 550-600Mbps. Rubbing further salt in the wound I should also mention the Hub5 is in my loft making it clearly further away from my Iphone than both access points which are on each floor of the house. Surely the APs should be outperforming the Hub 5?!

I'm hoping this is a config issue of some sort and that someone in this forum would be able to steer me in the direction on how to improve things.

Open to everyones suggestions - thanks in advance.

Yes - "smart queues" as its called in UniFi is disabled.

And, to answer your 2nd question - running a speedtest on my laptop and phone I can see that the total combined speed is around the 400Mbps mark

How odd!

Is 'Flow Control' enabled on the switch?

"2.4Ghz band should be on 1, 6 or 11 only ?  13 will overlap other channels?"

Channel 13 can be used in the UK instead of 11.

My name is NOT Alessandro. That's just a tag Virginmedia sticks on some contributors. Please ignore it.

Flow control is disabled too. Although I'm not entirely sure if this needs to be enabled or not - I'll assume not!

Personally, if I was testing WiFi throughput, I would not use an internet speed test... and fast.com is most useless anyway in my experience. I believe fast.com checks speeds to netflix CDN. I don't use netflix so pointless for me. Most ISPs will have great peering arrangements with Netflix and other nonsense but have terrible peering arrangements with everything else. Unless netflix is all you do on the internet, fast.com is pointless.

Fast and Reliable 5 GHz Band

The 5 GHz band of the U6-Lite is equipped with 2x2 MU-MIMO and OFDMA technology, boasting a radio rate of 1.2 Gbps. This ensures fast and reliable wireless connections, making it ideal for data-intensive tasks and high-density environments where network performance is crucial.

Versatile 2.4 GHz Band

The 2.4 GHz band of the U6-Lite features 2x2 MIMO technology with a radio rate of 300 Mbps. This band offers versatility, making it suitable for a wide range of devices and applications, ensuring that you can connect effectively across various scenarios.

Assuming the above is correct, how are your access points connecting to the Hub 5, as you say modem mode then this should be by cable. The cable should be minimum cat5e, which will suppoort upto 2.5 GHz. 

So assuming you using the 5.0 network your speeds should be upto 1.2GHz, the only reason to not get this is a device does not support it. To carry out a true test, all other devices need to be disconnected from the network.

This is what the Hub 5 Supports
