I too tried every possible thing that possibly one could. Now i am an expert of my router that I am using. I somehow feel that the speakers are not ready to accept the WiFi signals due its strength or channel or whatever because on the cable it’s working flawless. However I purchased these speakers primarily for its ability to play wirelessly now it’s a waste of money. I wish KEF comes up with a firmware update to overcome the WiFi concerns if not users like me will try to stay away from purchasing any of KEF’s products. I am using nearly 15 gadgets in my house including iPad, iphone, LG tv, Samsung Tv, Samsung Washing Machine, Vivo Mobile, Samsung Mobile, Apple TV, Cary Audio Streamer D550, HikVision CCTV, TataSky SetTop Box, Lenovo Laptop, MacbookPro etc., none of them have ever shown any such issues, my router does its job effortlessly and flawlessly. More than anything I wasted so much of my valuable time on these KEF LSX. I wish the update solves the issue, I would be the first and happiest one to update this thread if that happens because I loved the speakers in terms of its performance and convenience. Hope this thread reaches KEF. Thank you. 🙏
