@David-TP noob question but what does ethernet backhaul do and how does it extend coverage if the devices are next to each other?

I currently see an ethernet icon on the HB610 as a satellite. I'm not sure what that means in relation to backhauling, other than the obvious that it's connected via ethernet.

I have Kasa light switches on 3 floors, the garage and an RE270 extender in the 4th floor (basement). I can't extended coverage as a mesh because the IoT network is not availabe/disabled on the HB610. I probably should have bought another basic AC band extender for them since they're fixed, much cheaper.

off topic but I wish they came out with fewer similar models so that there would be more time and resources for support. Also a single app would have been great as currently I use Kasa, Tether and Aginet. If I get cameras, I'll have to add Tapo. Then there's Deco if you have that. I'm assuming Kasa is getting phased out so I'll have to keep an old Android/iOS device around since the app won't be avaiable on new devices. Edit: I just noticed Kasa devices are getting migrated to Tapo. The Kasa app is a better experience but one less app is good.

  @David-TP There's currently decent a sale for the RE655. I bought the HB610 for much less and it's technically supposed to do more, basically a BR router.

  @David-TP I was reading the manual of the RE655/53BE manual and they do not appear to have an IoT and Guest network. The HB610 seems like it's a real good product if everything works like it should.

  @David-TP Yeah but the HB210 currently does not support VPN client, which I need. I do not have upload speeds to use it as a server.

  @David-TP I submitted a ticket. They said hopefully engineering will do an update. That's pretty much all that can be done at this point.
