I had cablemodem with Insight. Something corporate happened, and now it's Comcast. My Internet just stopped working half an hour ago, and I decided to call rather than wait. Didn't have a Comcast number... but my old Insight number apparently feeds right in. It took a lot longer than usual to get a tech support person, who sounded a bit less friendly than usual, and had a different script, involving taking my router out, and obviously being skeptical of anything I said. Oh, and "I can't support non-Windows" like that should even matter to my computer dropping off the Internet. My rebooting the cablemodem and router didn't work. Eventually he did a remote reset of the modem, which worked while my computer was plugged directly into it, and he got sanctimonious about how if only I'd done it it would have worked. Hung up, and natually I put the wireless router back in. Whoops, not working again! I'm currently leaching off someone's unsecured wireless, I don't have the time to deal with this more.

Maybe it's time to try out AT&T.
