Frequently Asked Questions

What does amber LED mean on TP-Link Deco?
An amber LED on TP-Link Deco indicates either a slow internet connection below optimal speeds or that a firmware update is available. Check the Deco app for specific notifications about the issue.
How long does TP-Link Deco firmware update take?
TP-Link Deco firmware updates typically take 5-10 minutes to complete. All units in your mesh network will update automatically, and you should not power off any devices during this process.
Why is my Deco showing amber instead of white?
Your Deco shows amber instead of white because it's detecting suboptimal performance - either slow internet speeds or an available firmware update. A white LED indicates everything is working normally with good connection speeds.
Can I use my network while Deco LED is amber?
Yes, you can still use your network when the Deco LED is amber, but you may experience slower speeds or reduced performance. The amber light is a warning to check for improvements rather than a complete failure indicator.
