So these speakers that I love the performance of are back in the boxes in and my truck to go back to the dealer today, no idea how that will go. They simply will no longer connect to my wifi network, they stopped a couple weeks back and I dug into it last night. They network is solid Orbi mesh networking stuff. Monitored the network logged into the Orbi. Every single device in the house connects to the network without issue. Phones, ipads, gaming systems, iMac. Everything works. You turn on the KEFs and if you are on the wifi input, the wifi icon blinks for a few seconds while connecting then you are good to go. It never stops blinking. I did two factory resets and went through the new set-up protocol twice, but it fails at network connection. Then I downloaded the firmware update tool, moved to the speaker to a new room just feet away from an Orbi, still would not connect. And the speakers need to be on the wifi network to update the firmware. So basically when you start the KEFs they cast a signal, which my phone picks up and connects to which start the set up process, then step 8 of the process is dropping the KEFs onto my network and it fails there every time. There have been no network changes and as I said everything else is fine. Kef recommends 5Ghz connection, all the device in my house are connected at 5Ghz. I just have no idea what the problem could be.
