WiFi issues with Netgear Router

[HazelGrace]

Ive been using this netgear router (the AC1900 model C7000v2) for a long time an it has been working fine. However, today the downstream light is blinking, and the upstream and internet lights are completely out. However, my phone can connect to the WiFi, but it does not connect to the internet. I am using spectrum by the way. Is this a problem on my end or a problem with Spectrum?

   So, not a "WiFi issue", then.

   Most likely.

   Visit http://netgear.com/support , put in your model number, and look
for Documentation.  Get the User Manual (at least).  Read.  Look for the
LED descriptions and "Troubleshoot".
