Netgear CG3000D-RG Constantly drops wireless connection, internet does not work

I have to reset it when I wake up in the morning and then I reset it again when I get home from work. The wireless signal will go off and on by itself and the LAN connected laptop loses its internet connection. If I do not restart the modem at least 2 times a day it does not work. I can sit here and watch the wireless signal light disappear and then reappear 5 to 10 seconds later.  Anyone have ideas on how to have the internet consistently work?

  • So after I got home from work, had to reboot modem to get the internet to work again. Then at around 9:30pm I got booted from my wireless network and when I reconnected my internet speed was less that 1mb according to speed test so I had to turn it off and back on again to get back up to 20mbs. CenturyLink starting to look better and better every day.

  • I'm having the same problem and it looks like there are a lot of COX customers having this same problem.



    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 a test 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.

  • At least I am not alone then, too bad it ** for all of us. Have you found any type of fix yet?

  • The signal levels look fine for the modem and there does not appear to be any packet loss or latency that we can see to it. There are some errors in the logs for T4 time outs which would be tied to transmit issues and if constant enough can cause the resets. To check when the connection drops are your computers and wireless devices still showing connectivity but no internet access or a local only status? Or do they completely disconnect when you notice it saying no connection or network?

  • Edward,

    The wifi light on the modem starts blinking and then disappears and on my wireless devices I am booted out of the network. Then, sometimes it will connect back to the network and not have internet access, other times it will not be able to connect back to the network at all.  The only fix is to turn it off and then back on, I doing it 4 to 5 times a day now.
