Post back with the model number of your modem/router. . . Cox has several.

Maybe an outage with your service provider, call them

I have a cox internet in orange county CA. My wifi was working perfectly fine when suddenly my phone said it didn’t seem to be connected to internet and my online game crashed, then my pc said no internet.

went downstairs and the router was blinking orange. i unplugged it for a minute but that didnt fix anything. it just wont stop blinking orange and i have no wifi. what does an orange light mean? looked it up but got various answers

Consult the device’s manual. Blink signals aren’t standardized.

Either way you’ll likely end up calling your provier if the problem persists.
