Panoramic modem. Can a panoramic modem/router go bad? I've had intermittent connections for 2 days, lots of blinking orange and green lights but not much connecting. Also, modem seems warm. Modem only 3 months old.

Cox reissues their equipment so it may have been already faulty.  Have you tried rebooting?  If rebooting doesn't seem to help, try logging into your Cox account to reset your Internet modem.

Can you upload images of your modem logs...signals and events?
