Hello @am96v,

Welcome to our community.

High ping and ping spikes over Wi-Fi are typically related to wireless instability or interference. Here are some troubleshooting steps that should help improve your Wi-Fi performance and reduce latency:

Router Placement:
Make sure the router is properly placed in an open area instead of inside a cabinet or on a shelf. This can significantly impact wireless performance.

Optimize Wi-Fi Channels and Channel Width:
1. Log into the web interface of your router (http://tplinkwifi.net)
2. Go to Advanced > Wireless > Wireless Settings
3. Try different Wi-Fi channels to avoid nearby interference from other networks
4. For 2.4GHz connections, set the channel width to 20MHz
5. For 5GHz connections, set the channel width to 80MHz or 40MHz to reduce interference

Check for Restrictions:
Make sure your devices are not included in any Parental Control profiles, as this can affect performance.

Update Client Devices:
Ensure the network adapter drivers, system, or firmware on your affected devices (PC, phone, etc.) are up to date.
