Lesson learned. Update - I think I know how I should have done it - I should have edited my original post to show an update with the solution to my problem like I did in one of the posts. So sorry to be a bother - it probably does make Cox seem better than they are! I was just so thrilled that my problem was solved. Silly me! Re: Netgear CG3000D Modem Router Started Unicast Maintenance Ranging - No Response received - T3 time-out Thank you Scott Pickett for setting up a service call with a real Cox employee instead of a contractor. After 3 visits from End2End with each doing one little piece that did not fix my problem of slow speed, I went to the Cox store and talked to Scott about my frustration - he made sure my next appointment was with a Cox specialist who had experience in all systems. I have Cox Phone and Internet only. Scott (from the COX store) also replaced my 1 yr old modem (it had a 2 yr warranty) with a new version and confirmed my appointment with a Cox repair technician. James discovered that I had an old phone modem that could have been interfering with the internet signal coming into my house. It also could have been the internet modem, but when the End2End technician did atest from the tap with a brand new modem the slow speeds continued, so I figured it was not the internet modem. James the Cox repair person replaced the phone modem and the internet modem and I have not had throttling down to slow speeds for 3 days now. I'm a much happier person. Thank you Scott for saving a Cox customer for 8 years. Re: Modem/internet issue Thank you Scott Pickett for setting up a service call with a real Cox employee instead of a contractor.

I'm waiting for atech to visit - I think they gave up on me, but I will pass along your post info. What's weird is they ran a cable directly from the tap to a brand new modem and it did the same cycling down of speed. My problems started after a service outage 7 weeks ago, before that I've had no problems since I started with Cox in 2005. Re: Frequent Disconnections I'm having the same issue too. 3 techs/4 visits, tested new modem, updated firmware, changed parts outside house at box - ran line from tap to new modem - same issue - it all started for me with a service outage 7 weeks ago. Been a customer since 2005 when I moved into new construction home - even paid for "entertainment pack" with upgraded wiring and OnQ box. Nobody wants to go back and research that outage and how that might be related. Based on the many posts of the same issue - I'm more inclined to change service providers, since most people have lost hope of getting help with a fix.

Techs removed power booster from OnQ box, replaced parts outside, tested the signal from the tap with a brand new modem of same type NetGear CG3000D, same issue with unreliable speeds, cycling down to 1mb. They updated the firmware on my modem - still same issue. I have seen many posts in multiple forums of people having the same problem with no clear resolution. I'm spending many hours researching forums to see what the resolution was - and can't find any. I created my own forum post to see if anyone has any magic fix. Still searching.
