Hello @Alohomora ,

Welcome to our community.

For your case, the following are some suggestions that may help:

For WAN connection instability (if the router's Internet LED turns red/orange occasionally):
1. Connect a PC directly into your modem to verify if your ISP Internet is stable.
2. Make sure the Ethernet cable between your modem and the router is connected properly; replace old cables with new ones if needed.
3. Change the DNS Server of the router: login to the web management interface, go to Advanced > Network > Internet > Advanced Settings, and change the two DNS Servers to 1.1.1.1 and 8.8.8.8.

For wireless client devices dropping :
1. Make sure the router is properly placed in an open area instead of inside a cabinet or shelf.
2. In the web interface, go to Advanced > Wireless > Wireless Settings, and try different Wi-Fi channels to avoid nearby interference. Additionally, for 2.4GHz wireless client devices, set the 2.4GHz channel width to 20MHz; for 5GHz wireless client devices, set the 5GHz channel width to 80MHz or 40MHz to avoid interference.
3. Make sure the client devices are not included in any Parental Control profiles.
4. Make sure the network adapter drivers, system, or firmware on the affected client devices (your phones and laptops) are up to date.
