For the last couple of days I have had no Internet access. I've tried resetting everything by unplugging things and hitting the reset button, but nothing works. I've noticed that the US and DS buttons on the modem are blinking, which they didn't do before.
Can anybody offer any advice on what this might mean. I am definitely NOT technology savvy so any help would be appreciated. My cable and phone are working.
That is very bad, and means you can not connect, US is the first phase and means upstream,
and ds means downstream.
To connect the modem needs to find the downstream signals and get its clock synced to the right frequency and to locate all the channels. Then it needs to find the upstream channel and adjust its power till the other side sees it, it needs to lock the phase correctly of the signal so it can transmit in the correct time slots or so.
The US and DS lights mean the modem is trying to do that phase of calibration, so it means that the wire must not be very good, or disconnected, or bad or the modem has failed.
Bottom line regardless of any technical mumbo jumbo accurate or not, this is primarily a customer to customer type of help venue here so you are not speaking directly to Comcast employees. So have you called this in ?
Do you also have their T.V. service ? If so, is that down as well ?
I have also been having the same issue. The tech was here two days ago knowing what modem I have but still brought the same one to replace it. He then got on the phone and told me I need to upgrade my modem. They were already aware that I need the upgrade but still sent the guy with the same modem, (TM602G/CT). The best part is this morning I received a phone call the day after the tech was here, which was a recording, from Comcast TELLING me that I need to upgrade my modem but I have to do it online. Why couldn't they just send one with the tech???
Sorry for my rant but this may be your issue as well as a lot of Comcast subscribers with certain modems that are experiencing this issue.
