Here are some simple checks to help you identify what's causing speed issues
Connect your laptop to the main router using a LAN cable and run a speed test using Speedtest by Ookla
Use 5GHz for better performance — ideal for streaming, calls, and gaming
Switch to 2.4GHz for better range in far rooms
Limit connected devices — too many can slow down your speed
Mesh systems connected via 2.4GHz may show slower speeds
Restart your setup in this order: modem → router → mesh unit
Avoid placing mesh units or routers in enclosed or cluttered spaces
