I unplugged my modem from the coaxial cable for a few hours while setting up a new entertainment setup. I plug it back in and it won't go online. Only the power light is lit and the US/DS light flashes. I call and they say its offline and have me replace the cable and try other cable outlets. None of that works. They suggest I replace the modem. Get a new modem,same brand, from Comcast service center hook it up. Same issue. Now I have a tech scheduled for Monday since no tech onsite support over the weekend?!? I work from home remotely. Needless to say that will be hard without internet what could have happened that's preventing me from getting online again? Any ideas or help would be appreciated.
