Mesh network versus a simple Wi-Fi extender

I use Ethernet Over Powerline boxes so I avoid wireless altogether without needing to run cables. One wireless box is downstairs next to my router and the other is upstairs in my bedroom. It's the best of both worlds and more boxes can be added throughout the house at key places. 

Netgear Orbi WiFi 6 devices are extremely stable. We use a four satellite mesh network in a 5,000 sq ft 1867 brick home that serves as our local historical society HQ and that mesh system was a game changer. Device allocation can be monitored from the phones of our staff, including a hifi Bluetooth streamer in the ball room, where most of our events and zoom meetings are held. Best $2,200 we’ve spent in recent years.

@soix I assume that the problem you have is that your streamer is near your router but still has dropouts using Wi-Fi.  Unless your streamer has substandard built in Wi-Fi streaming capabilities, you may just need a new modem and router with greater speed and capabilities than your current set up. As with many things electronic, the capabilities of these have increased dramatically,

A Wi-Fi extender will cut your speed in half. A mesh system satellite has a separate backhaul channel so it runs at full speed. I use the Netgear Orbi which gives me 4 ethernet plugs at each router . It has worked out flawlessly for me and sped things up greatly when accessing my NAS and streaming services. It's a pricey unit but it is fast and reliable.
