Large downloads killing wifi

[garbs123]

Wifi in the house is fine until I start doing any large downloads (Windows updates/downloading games on Steam)

It's fine for a few minutes then BOOM, all devices have no internet (wifi).

Not sure if it's some sort of throttling that the hub just cuts out or a faulty hub (I have a Hub 3.0) - Have to then restart the Hub to restore.

Anyone else had this or any ideas or how to fix this?

Use an Ethernet cable. The Hub sounds like it is being overloaded.

Our Hub 3 has reliable WiFi

We have Disabled Channel Optimisation and selected Manual Channels on both bands.

Unable to use an ethernet - every device is wifi only 😞

If it help below is how we have our Hub 3 WiFi ... image may take time to show ...

Also on the Security page we have Security set to WPA2-PSK  ( with the older WPA-PSK mode disabled to stop iPhone weak security grumbles )
