You Cannot rely just on your Router for full household signal
I've rated NOT easy to set up, only because this was pre-owned and the seller failed to tell me the password for wi-fi had been changed. Took a while to sort out via devolo cockpit on the configuration page.
If you're buying new, there will be no problem at all.
I have 3 wifi plugs and 5 basics, all feeding laptops, smart tv, roku's , smart bluray player in cinema room. Ring doorbell etc and they've all performed perfectly over many years.
I'll also move one to an outside socket in the garden to get wifi on my phone or whatever else I or visitors may be using.
All Tickety Boo !!
