CoxTech1 Member 2011-Oct-24 8:59 am Way too many Ethernet active/dormant events in those modem logs. Have you tried different Ethernet cables or connecting different devices to the modem to see if you still have problems? | |||||||||

| MastaMatt | MastaMatt Member 2011-Oct-24 9:06 am Yes 3 ethernet cables all same results...what do u mean by different devices? I only have one computer and its direct connection..tried onboard/ 2 nic cards also--same results (even tcp/ip tweaks/windows defaults) whole nine yards. Same results in safe mode w/networking. | |||||||||

CoxTech1 Member 2011-Oct-24 9:11 am You could maybe try updating the drivers on the PC but that pattern of log entries suggests a failed Ethernet connection between the modem and connected device. Do you have access to a laptop or something you could try connecting to the modem? | |||||||||

| MastaMatt | MastaMatt Member 2011-Oct-24 9:16 am Well I do have a cox tech coming today (3rd trip) do they carry laptops? Yea I figured it looks like a bad connection through modem to desktop but 3 different nic's and 3 different ethernet cables and still same results makes me scratch my head--unless somehow the motherboard itself is dying..but no other problems have been occurring. Also the packet loss doesn't occur in the morning--seems to be during rush hour in the evening when everyone is coming home.. | |||||||||

CoxTech1 Member 2011-Oct-24 9:20 am The thing to note about Ethernet events is they have nothing to do with the Internet connection. They simply indicate a loss of connectivity between the modem and whatever device is connected. It's possible that you have an out of box defect modem. Are your two NICs in the PC onboard? If so, have you tried an add on card instead? | |||||||||

CoxTech1 Member 2011-Oct-24 9:43 am That's all pretty much normal log noise during a reboot cycle but when you start seeing lots of Ethernet link up and Ethernet link dormant events outside of the modem rebooting there is definitely a problem. | |||||||||

This 2nd modem was free to my knowledge--I'm on 25/5 plan. Not sure what the 3rd tech is bringing in regards to laptop to test on and/or another modem.. | |||||||||

CoxTech1 Member 2011-Oct-24 10:09 am Cox technicians carry laptops with them which allows them to access our internal network giving them access to diagnostic tools and account information but they can try connecting them to modems for troubleshooting purposes. There are many benefits to getting a 3.0 modem but that would be an upgrade the customer is responsible for purchasing if desired. If the current modem came from us and is still under warranty it would be replaced with a comparable modem. | |||||||||
