trouble with my personal modem/router

[Krynn72]

Let me start by saying I'm pretty clueless at networking stuff, I'm entirely break/fix so far. So I'm not familiar with a lot of this and have only done some basic troubleshooting.

So when I leave this morning I'm online no problem (watched some Netflix before leaving for work). I get home and my ps4 won't connect to the internet, my pc has "no internet access" and my phone won't connect when on the WiFi. I have Comcast as my isp, and a netgear c3000-100nas router/modem. The device is about 4 months old.

The power led on the router/modem comes on, the network led comes on, but the down stream led just blinks indefinitely, and all the others stay dark.

I've reset the device every way I can (unplugged, hit the power switch, and did it through the browser login). I've disconnected and reseated all the wires including the coax from the wall. I've even done a factory restore. The browser login says "in progress" under the "cable connection" section summary, and if I go into the section it says "your modem is offline. Please check the RF connection"

I check with Comcast's service outage link and it says everything is fine on their end.

So did my modem just crap out, is it possibly something on Comcast's end still, or is there something I haven't tried yet that may fix it? Thanks in advance for any help!

Call Comcast. The blinking downstream LED means the unit is looking for a downstream channel.

Thanks. I went to Comcast.com again to find their number, and it's now posting an alert saying an internet outage is reported in my area, and that test I tried before now fails. So looks like that's my problem, says they expect it back up by 1am.

I feel like one of my customers now, what am I supposed to do at night if I can't watch Netflix?! Maybe I should find a new girlfriend. That way I can use her Netflix when this happens.

Yes, this. They can send a refresh signal and also determine if the modem/router is functioning, that is, if they get a successful ping/return signal from it.

In my area (Penna) Comcast is very good with their service/tech issues, contrary to the storied I have heard in other parts of the country.

They've been pretty good to me too. This is a new location for them (I'm their first customer at this address) and I know there's construction going on like 50ft away from me on some new apartments so I thought maybe something happened there too. But I grew up on the other side of town, and we've had Comcast there for the better part of my life, and I think we only ever had service issues once that I can remember, and one time where we had to call them to get a docsis 3 modem because or speeds were less than what we were paying for. I've lived in other states and used different providers, and Comcast has far and away been the best.

Don't get me wrong, I still hate the company and think they're one of the most mortally bankrupt corporations there is... but hey, it's either them or at&t here. If I gotta sell my soul to the devil either way, I might as well get good service out of it.

I'm also a Comcast customer. About a year ago my internet service would cut out intermittently for a few moments and then return. After a few weeks of poor support from low level noobs reading from a script or onsite techs who would measure my signal and claim it wasn't their problem I freaked out on the phone and demanded to speak to a manager. I told him to stop blaming my PC's, start putting his techs to work and keep me in the loop.

I knew it was a poor connection somewhere nearby and for the life of me I couldn't understand how they didn't realize this also.

I tried escalating the call late one night figuring the 2nd shift management would be more responsive and it worked. This guy called me a few times explaining his action plan and they eventually found the issue on a pole down the road and fixed it.

They are like any other company. You have people who care and people who just want their check.
