CG3000DCR Intermittent Connectivity
I had an SMC-8014 modem for several years and never had a problem. Unfortunately, that modem bit the bullet a few weeks ago and a Comcast tech replaced it with a Netgear CG3000DCR. I have been having nothing but problems with the Netgear with respect to intermittent connectivity problems. I will be surfing the web, and all of a sudden a page will not load. Sometimes the lapse is just a few seconds, other times slightly longer. When the connectivity lapse occurs, if I logon to the gateway web console and go to the 'Administration', 'Diagnostic Tools' page and attempt a ping of say 'www.yahoo.com' it will either fail to get a response or sometimes fail to DNS resolve.
My configuration is as follows:
I have a static 5 IP block
I have changed the subnet on the CG3000DCR to 192.168.0.x; specifically, the gateway is 192.168.0.89
I have disabled DHCP on the CG3000DCR
I run a local DHCP server which doles out IPs in the 192.168.0.x subnet and 192.168.0.89 as the gateway address.
The Netgear is:
Hardware Version 1.04
Firmware Version: V1.33.03
If i run a ping loop to www.yahoo.com from a console window on one of my machines I see requests fail in blocks sometimes and occassional high ping times of 200+ms (the average is ussuall 20ms)
I have had a tech come out and replace the modem with another CG3000DCR. This made absolutely no difference. The tech also did a line test and said things look OK. He then proceeded to claim that perhaps the problems were due to "a mouse chewing on the wire in the wall" (no joke). There are no mice in my walls and I kindly informed the tech that prior to the Netgear I had no issues -- my local configuration has not changes at all (apart from the introduction of the Netgear)
I reiterate that I had no problems with the SMC-8014. It gave me several years of reliable service. I have another tech supposedly coming out in a couple of days. Is there something I can change or try in my configuration to possibly resolve the intermittent connectivity? Is there something else I can look at?
