What was the status light on the modem? and when did it start?

There is a red light on the modem and it stopped working a few hours ago

You will need to schedule a callback through Koodo Assist and speak with a rep for further assistance. https://Koo.do/Chat 

Was the light “red” or “red flashing”? If it was flashing, the modem might try to reset. If the light was a constant red, the physical internet line could be the issue and you will have to contact Koodo. More information here https://www.koodomobile.com/en/help/understanding-your-modem-and-router?
