S33 modem stopped providing internet service. Front panel LED is flashing green at Avery high rate for speed. Tried power off for multiple minutes. Tried resetting and reboot procedures. Same LED high flash rate (essentially a flicked). Tried direct computer network connection to access the modem default IP address, no response from the S33 unit. 
Any other options to get this unit working?  Was purchased 3/31/23 and is still under warranty. Not sure how to make replacement claim if the S33 is truly dead.
