depends entirely on your budget and what "features" you deem as non-negotiable.
note - the hue lighting is not relevant as it doesn't use your WIFI network. the hue bridge connects via ethernet and the bulbs connect to the bridge via their own zigbee network, not your WIFI network.
problem is, you could spend £300 on a high quality router and it would still have poor wifi as wifi is affected by location conditions such as the layout of the house, the thickness and types of internal walls, the position of with wifi router, the amount of other wifi networks in close vicinity.
wifi is a dark art and just because a router works great for 1 person doesn't mean it will work great for another.
so, where will the router be located? what is the house layout like? how many floors, rooms etc. reaching out to the garden.. how far out?
Just bought from amazon a Linksys Velop mesh wifi, three devices for £136, easy to set up using an app on your phone, got rid of the dodgy wifi provided by the hub, strong signal throughout all three levels of the house. Just turned off the wifi from the hub 3.0 got great wifi instead
The better systems use either hardwire back to stop this or a hidden channel to reduce overheads. Checked speed which was 40 using Virgin hub is now 200 wirelessly dropping to 150 on the third floor. I think that is acceptable and better than trying to run cat6 cables everywhere, ever remembering that all right corners and splitting the pairs seriously causes problems. Not to mention the inflexibility
