 # How to Improve Lag
 
+## Client Lag
+
+If the `TPS` (Press Tab to see it) is `20` then the server is *not* lagging and it's your client. You can try the following to troubleshoot your client connection:
+
+- Restart your router.
+- Try joining the server with [Raknetify](./Features/raknetify.md). 
+- Using a VPN to Germany might also help.
+- If everyone on the server has a bad ping (type `[ping]` in chat) then immediately inform the server owner!
+
+## Server Lag
+
 We're all playing on the same server and sharing the same ressources. If everyone makes just very small changes to their farms and redstone, it can have a huge impact on server performance. 
 
 Better performance allows us to build even crazier Redstone contraptions and use a larger simulation distance without lagging the server. 
 
 Below are a few things that you can do to improve server lag without having any impact on your gameplay:
