  • Page 96: Speaker Connection Test

    The speaker connection test in KEF Connect shows you how much network bandwidth is available to your KEF wireless speaker system. It considers every stage of your network by downloading a file from a random server to the speakers – from the bandwidth provided by your internet service provider (ISP) and server traffic, all the way to the speed of the connection between your router and speakers.
  • Page 97 ISP is providing but will not tell you specifically what bandwidth your KEF speaker system will be able to take advantage of. The KEF Connect speaker connection test more closely represents what happens...
  • Page 98 If connected by Ethernet cable: 1. Ensure the router firmware is updated. This is a basic step for any electronic device, as updated firmware may address known bugs. 2. Reboot the router. Routers are basically computers and are affected by the same problems. Bugs and temporary errors can cause too much memory being used, or the router can be overheating (one reason to not place it in an enclosed space!).
  • Page 99 If you have a lot of devices on the 2.4 GHz band, then there may be little available bandwidth left. If your KEF speaker system is close to the router and has little to no obstructions, try connecting it to the 5 GHz band for more bandwidth. If there are obstructions, try migrating network devices that are closer to the router to the 5 GHz band instead, freeing up bandwidth on the 2.4 GHz band.
  • Page 100 It is also worth noting that different router manufacturers handle mesh technology differently, and there may be compatibility issues with networked devices.
