@JRR1980 most likely cause is WiFi interference which often gets worse in the evening as signals carrybfurther. A reboot of the hub can help as thst causes the hub tonfind the lesst congested WiFi channels to use which can help if the source of the interference is a neighbour's WiFi. However the source could be a faulty electrical devicecin your home so check thst the problem does not hapoen when you use the microwave for example butvthe dource can be a didgy light or many other things.
The best long term solution is getting a better WiFi set up with multiple units creating a mesh network. If you buy Sky's WiFi Max bundle the extenders Sky will supply if asked will domthst ir you can buy a third party mesh system quite cheaply.
