If you are gaming online the best way to experience lower latencies is by directly connecting an Ethernet cable (Cat 5 or 6 is recommended) from your modem to your device. This is because a wired connection is faster and more reliable than a wireless connection.
However, if you are playing on a wireless connection you can reduce latency and lag is by optimizing your WiFi. Start by preventing WiFi interference by placing your router in an open space towards the center of the house, reducing the number of devices on your WiFi, and cleaning your devices of viruses or malware. Your modems may also need to be updated.
You may consider a whole home WiFi solution — like eero — to help extend your internet’s reach to every corner of your home. If you’ve taken steps to increase your WiFi speeds and it isn’t working, re-evaluate what internet is best for your household. With more WiFi use, it may be time to upgrade your internet.
