@GastondZ kinda defeats the object of having a mesh network.

  @CraigRX7 Not sure if this will help you or not, but Amazon has a process to allow refunds after the 30-day refund period.  I had an ice maker for my outdoor bar which stopped working during the manufacturer's warranty period.  The manufacturer was no help...I called repeatedly, and they did not solve the problem.  I eventually called Amazon to see if they could help push the manufacturer to replace the ice maker.  Instead, Amazon offered me a prorated refund.  You probably won't get the full amount back, but might not be a bad idea to see what they can offer.

  @vinny.fernandez thanks for the pointer. I just contacted them on their chat service, navigated a few dead ends trying to get me to contact TP-Link and eventually they have issued a return with promise of a full refund! Now to figure out an alternative...

  @CraigRX7 That's awesome news!  Happy to hear it!  glad to help :-)

  @GastondZ Hey Gaston,

Do you mean each deco connected to a core switch?

Mine are the PoEs so that is currently my setup.

  @TP-Link , your devices just don't work.

I have lots of Decos. Most of them hardwired back to the main unit. One of the hardwired ones (a satellite to the main unit) is 10 feet from my Macbook. Pings are fine. Speedtest is fine. Teams, connections drop. Video freezes. Audio freezes. I don't have this issue with my laptop elsewhere, just with my deco. It's a deco thing as others are saying. I'm in for thousands of dollars. I would be happy to replace it with something else if I could get a refund, but that's not a simple option.

TP-Link, look at my account. Please, make a helpful recommendation. All the firmware is up-to-date. I've rebooted the units. I'm literally a few feet away from a hardwired unit. You've already failed to deliver on the promise of mesh - I've drilled holes in my house to run hard wire to try to recover some value for this system. What I'm looking for now is the basics of 802.11 - just wifi from my computer to an access point. Mesh is off. Fast roaming is off. Beam forming is off. All the bells and whistles are off. My laptop is hard set to a specific AP. It has a strong signal. Outside of Teams, it's working fine.

Please, provide a helpful response to all the frustrated users on this thread that respects all the work that people have done before coming here to ask for help. All my tech is up-to-date. It's a you thing, not a me thing.

Please, help.
