@jfletch133,

What have you tried if anything?

Are you issing the Deco App? What does it show for the Internet?

Same if using the Web GUI?

On the main Deco, does the light show green?

What OS are you running, and it that showing no Internet?

Have you tried a different SSID?

Have you 'swapped' Deco's to rule out the problem being the Deco conected to the Modem?

Have you power off the MODEM and DECO, then powered up the MODEM and when fully up the main Deco and tested?

I have same issue. Multiple times. Workaround is to power cycle main ap once power is stable. With they would fix it though.
