Frequently Asked Questions

What do flashing blue lights on the TP-Link mean?

TP-Link Deco mesh routers use blue light to indicate their working status. If you are using a Deco and notice the lights are flashing blue, it denotes the device is ready for the initial setup. However, if your Deco flash a red light, the firmware update is ongoing.

Why are my TP-Link status lights blinking?

Every time you see the TP-Link lights blinking, it doesn’t mean something is at fault. When a port or band is active and transmitting data back and forth, you’ll notice the lights blinking, which is ideal.

Why is my TP-Link connected but no internet?

If your router is connected, but there is no internet, it could be a problem with your ISP. Check for outages or scheduled maintenance. Once that’s ruled out, check for any loose connections or faulty/damaged cables. Contact your ISP for further guidance if that doesn’t seem to be the case.

Flashing green lights doesn’t always mean something is wrong with your TP-Link router. In case you see an orange or red light in the Internet LED, that’s when your router requires your immediate attention.
