About JayQue2

Another month has came & gone with literally nothing being done about my issue. Local techs are of no help. They won't look at neighbors lines unless those neighbors actually complain. Almost a year of this! 2 more months. ... View more

Thanks for your continuous support on this @EG . I was contacted directly by an Executive Customer Relations Agent recently regarding my issue. Fingers crossed this gets resolved soon. ... View more

They've stopped troubleshooting my issue since "everything looks good" on their end. All they do is check their apps/software here. Wish this local team was as diligent as others. Good luck getting it fixed. Please post any updates on your issue. Hopefully it can be of use to my local maintenance team. ... View more

It appears Comcast/Xfinity has given up on this matter. I will no longer be receiving support from them per the local Manager tech saying they can't replicate my issue on there end. Now I'm stuck with service that they can't provide/fix & a contract that was modified without my consent. How can an ongoing issue like this not be intervened by a corporate employee? There are cables above ground in the gated community I live in that they wont come bury. They have even cancelled tech visits I scheduled to do so, claiming I was the one that canceled. This is what I've been dealing with. Now all the power has been given to the local team that solely relies on there software/apps for troubleshooting with the answer that everything looks good on their end. LOL. Kinda comedic. So what next? They cant fix my service or my bill & my issue is being ignored. Do I actually have to go through the complaint process through the FCC now? ... View more

Thought I'd link the Netgear conversation here for reference.   https://community.netgear.com/t5/Cable-Modems-Routers/c7000-T3-T4-timeouts-amp-US-Light-blinking/m-p/1834049#M20891 ... View more

This is what my event log says. This all srarted after maintanance was done in my area. Also happened with a Xfinity provided modem & my neighbors are also having issues. All cables in my home are New per Xfinity. Netgear: " T3 timeouts and " No UCDs Received " is concerning.  Has ISP checked the noise on the Upstream/reverse path and confirmed?" Xfinity: "Everything is in the green."  2019-12-8, 09:37:43 Critical (3) Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=2c:30:33:bb:64:c0;CMTS-MAC=00:59:dc:79:6b:22;CM-QOS=1.1;CM-VER=3.0;

Still waiting for a fix on this. Now my bill can't seem to be fixed either after it was changed without my consent in October. What do I do next? What does one do after Comcast stops troubleshooting your Internet because "everything looks good on their end" & can't fix your billing issue that they created? I've been chatting on Facebook for over 6 hours literally repeating myself to different techs who claim to be corporate level techs. Internet issue for a total of 8 months & billing issue for 2 months. What next? ... View more

Same exact issue here. Had it for 8 months now. Still looking into it myself. Please post an update if any. Thanks in advance. ... View more

Sounds good @EG . By any chance have you ever seen or heard of what I mentioned? About there being a quick fix involving a phone rep & a tech..? I've seen it once & a follow up install call from Xfinity a few months ago said he knew exactly what was happening & assured me it was not the cabling and/or modem. Said he's worked with modems for years & could fix it with the tech on the line. Unfortunately the tech had already left. So I know there's a fix for sure. ... View more

@JayQue2 wrote: Just an update for the public on the matter. Issue with my Internet is still present. Swapped my Netgear c7000 for a Xfinity issued one for testing purposes and ended up with the same results. Techs can't seem to figure out what the modem event log files, automated phone system AKA modem health check & the Rep on these forums see. The Techs involved are both a Supervisor & a Manager, yet they see no issues on my end. Not sure if anyone can chime in. Any helpful info is greatly appreciated. Update #2. Still no fix. Modem has been monitored for some time now & no one seems to know what's the issue. I was informed the engineering department got involved yet can't figure it out. On a side note. I've had this issue before in the past & was immediately fixed by a savvy phone rep who knew it was not the modem or cabling & got on the phone with the tech & together they fixed it. So I do have hope in this getting fixed. Still waiting for a fix. ... View more

Issue still there after multiple reboots, factory resets & pressing and holding the reset button for 30 seconds. Uncorrectables seem to get fixed upon reboot, but return after a few minutes. Issue happens on both wired & wireless devices. Not sure why techs wont drop a new line to my living room from the box outside my home.., being that the original wiring in the walls is from 2004 & has splitters in rooms that tap into other rooms. Phone reps still say they see timeouts and assure me it is Not my modem. The back & forth is stressful to say the least. ... View more

Here are the requested screenshots. I have power cycled the device which ended with the same results. A customer service rep did notice a second device on my account (should only be one), so she removed both devices then re-provisioned my actual device with same result on my end. FYI: Last residential tech here installed an attenuator which solved the issue momentarily. Original in wall wiring in the home jumps from room to room from outside.             ... View more
