R6020 router saying offline

[BL333]

I just plugged my router back in after being away for a while, and it keeps saying offline on the iOS app. My devices can connect to the router, but there’s no internet connection. All the lights are on except for the very last one. I’ve tried rebooting it and it says there are no updates available yet. Firmware V1.0.0.48. Help!

What modem/gateway is it connected to? 

did you power off the modem/gateway and the router for 2 minutes.

then boot up the modem and give it 2 minutes. 

Then connect the router and boot it up.
