# KEF Troubleshooting --- ## KEF Troubleshooting (LSX/LS50s) Often times when we see reports of KEF issues the following troubleshooting steps are useful in narrowing down where exactly the issue lies: * Are the KEF speakers using the 5Ghz WiFi network and not 2.4Ghz? * Is there any change if connecting both the Core and the speakers via Ethernet to the primary router? * Have the KEF Speakers been updated to the newest firmware version using the KEF Control App? * If you are using the LSX, is there any change if they are connected to each-other using Ethernet and set to "Cabled Mode" in the KEF Control App? * Does this issue only occur with higher sample rates? If you have run all of the above suggestions and are still experiencing issues with your KEF speakers please [reach out to our support staff on Community](https://community.roonlabs.com/t/im-having-a-problem-with-roon-where-do-i-report-it/2185/5).
