WiFi experience

No, decent mesh kit usually has mimo with multiple radios in each unit, so it can transmit to several clients clients and on the backhaul connections to other mesh devices at the same time.

It may also support beam forming to allow directional targetting of devices, which again can free spectrum in some directions as well as optimise bandwidth use and use lower transmit power.

(dual band kit may also have band steering as well which will push capable clients up onto 5GHz where its supported and advantageous - so that frees up 2.4GHz capacity)

I have several Sonos speakers throughout the house configured to use their own mesh network and (although I think Sonos is vastly overrated) their performance is rock solid even in far-off rooms.

If mesh routers are anything like that then they would be quite impressive.

You could do a mesh setup.

While parts of this article are silly marketing, the ability for Wifi box nodes to store and forward can be useful.

But at least in the case of that product description, there's a range checker that checks whether where the second mesh box is sitting, it is in a good enough spot.

This is a tech for someone with money, because buying three boxen adds up.

You could stop buying them, once you've got coverage.

More examples here. Items have a review page with tests.

I have only limited experience with them so far, but they do seem to do what they are supposed to.

I have one client that wanted decent wifi at home - this is in a large modern place spread over three floors. Normal wifi with just one router was no use. So originally we went for a system with wifi on the router in the office downstairs to provide coverage there, then homeplug links to access points on the other two storeys. (this was using all Draytek kit - so not your typical home wifi). That worked well until the start of lockdown, and much heavier use was being made of wifi with more people at home streaming video, plus no doubt neighbours doing the same. Plus he wanted to wifi an outbuilding. So it was time to shift gear on the implementation.

In the end I deployed TP Link Deco P9 units (these are hybrid mesh wifi / homeplug units) In the end using a total of 6 devices (probably overkil, 4 would have done but they come in three packs!) That seems to have coped with everything asked of it, and it was simple enough I could even get the (really non techie!) client to set them up with his phone with a bit of coaching)

DHCP is handled exclusively by the router. Several are static and it is set up with long expire times (a few days, IIRC).

Never even think about it these days. It just works.

I can see all the devices on the network - no problem - from anywhere.
