CG3000D-RG and connection errors

[deesigner2]

I have Cox communications as my ISP. I have a netgear CG3000D-RG that is about 2 years old. I started having connection issues last summer. they continue randomly. I have had COX out and they measured signal levels and replaced cable from street to house. I have replaced CAT5e cable in the house. I have a laptop and a worsening connection issue, to the point I have to unplug and reinitialize the unit. Nothing has changed in the setup or location of the router. I went into the event log last night and took a screen shot. that pretty much tells the story.I would like to send the screen shot but see there is no way to attach it here????? getting critical errors HELP

Hello deesigner2

You can attach the screenshot here you just got to click the little picture button that has a little mountain and sun in it. But if thats not working you can always upload it to a site and link it so we can see what is going on.

i called Netgear and the rep said I didnt have latest firmware, which was the first thing I had already thought of, but i looked at the site and I DO have the latest. which has to be done by Cox, the ISP anyway, as there is nothing in the interface to allow a binary update. Secondly, she had me change the channel from auto to 11 but that has not resolved the issue.

You may want to do a factory reset and start from new to see if the connection is more stable. Also did you buy this modem or is it from COX?

I already did a factory reset. still has intermittent connection. I bought it from Cox June 2013. they were the ones telling me that my service level of bandwidth is impacting the connection. WRONG. I don't do steaming videos or gaming.

yea I would say there is a cable issue with cox or the modem is going bad its really hard to say since there are alot of factors for cable connections to be bad such as cable in the house splitters or even a area issue with the cable infrastructure.  I do see from your screenshot that you are getting T4 and T3 timeouts here is a good article describing those.

since I replaced the CAT 5e cable and the Cox guys came out to measure signal strength two months ago, the only other step I can take is to  buy another cable modem and see if that clears up the issue. Thanks for link to the T3, T4 errors.

I had the same problem with mine but I am with Time Warner Cable.  I must have called in about 100 times (just kidding but it felt that way) to resolve the issue.  After running around in circles with these incompetant tech support guys I finally got one that knew his stuff.  I suggest you keep calling in over and over until they fix the issue.  Everytime I called in they had me do the same "CANNED" instructions. Unplug modem, restart your modem.... etc.  finally they looked at my log of connections and they say that my signal was intermittently being dropped over a period of a week.  So they said that they had given new codes to the server on my account and that that would not happen again.  

Well guess what?  That is true... it has not occured ever since this fix.  I tell you this guy knew his stuff - not like all of the other uncompetants I dealt with.

Just thought I would share and if possible use this insight to your problem.  By the way the tech at Time Warner Cable's name is Sharon Brooklyn.
