IOS 14.3 not connecting to WIFI

[NMolyneux]

I have an iPhone ProMax running IOS14.3.  I am new to Virgin and have recently set up WIFI.  My phone connects to the WIFI but doesn't appear to actually be using it as it is incredibly slow.  When I disconnect from WIFI it speeds up.  I never had this issue with my old provider BT!

Has anyone else had this issue and managed to find a fix?

Are you connecting to your Wifi network and not the public hotspot one?

[NMolyneux]

Alas definitely the private one!

You may be as well refining your Wi-Fi management, it will certainly help keeping track of your Wi-Fi frequencies.

Best done with a cable connected device.

Instructions for Hub 3, Hub 4 is similar.

Log in to the Hub.

Advanced Settings > Wireless Signal > click ‘Disable Channel Optimization’ > Click ‘Apply Changes’.

Advanced Settings > Wireless > Security > Add 2 to the 2.4GHz Channel name [SSID] > Add 5 to the 5 GHz Channel name [SSID] > Click ‘Apply Changes’

You can leave the passwords the same as they are. 

You will need to reconnect all you Wi-Fi devices some will want to connect to 5Ghz and some to 2.4GHz and some will connect to either.

When you connect the devices do it at the furthest point from the Hub that the device will be used.

2.4GHz is a stronger signal but slower than 5GHz so if you have problems on 5GHz change to 2.4GHz.

Check the Wi-Fi speeds on both SSIDs.

Mike's right - the iPhone will perform far better on the 5GHz channel - I get 220Mbps on our 200 service on my iP7 on 14.3
