Media Disconnected, NIC Failure?

Yesterday while at a clients home working on programming a remote control I noticed that the Netgear WG602WAP was malfunctioning. Because I had a little bit of trouble with this particular WAP previously, I called Netgear support and after an hour of boiler plate troubleshooting scripts the manufacturer issued an RMA. In the process of troubleshooting I connected my ACER laptop directly to the WAP to access the setup menus etc.... When I next tried to connect to the internet with the ACER (LAN connection), the NIC behaved as if it were malfunctioning. I checked with my network specialist and even though we could ping the card etc... he concluded that the NIC must have croaked. Today, I was back at the clients with a replacement WG602 and a different laptop. I successfully configured the WAP but when I returned home, I no longer have internet access. When I run the command ipconfig /release, the error message reads "Media disconnected, unable to run this operation" or words to that effect.
All diagnostics point to the card being in good working order but I cannot connect to the internet so that would suggest otherwise. I suspect that both NIC's are OK but I can't connect over the LAN. Thoughts and suggestions appreciated.

Hello again. Tried "release/renew" commands. this time the first command successfully executed but the "renew" command resulted in this error message "error occurred while renewing interface Wireless network connection. Unable to contact your DHCP server"

I do not have a wireless access point deployed here.

Hey DF Simmons,

It gives me an appropriate address for the ethernet adapter but it DHCP is not enabled. I do not recall where to change that setting. Trust me I've been looking...

  • Click Start, select Run, type ncpa.cpl and press OK
  • In the new window, right-click on your Network Connection and select Properties.
  • Select Internet Protocol Version (TCP/IP) and then press the Properties button.
  • Select the option Obtain an IP address automatically and Obtain DNS server address automatically
  • Press OK.
If this doesn't resolve your issue, please do the following:

Step 1 - Connectivity test:
  • Press Start
  • Select Run
  • Type cmd and press OK
  • In the new command prompt window, please type the following commands (*Note: each ping will take approximately 10 seconds to complete; wait for the command prompt to return before you type the next one. Also, the single '>' and double '>>' are intentional; please type the commands exactly as they appear):
    • ipconfig /all > C:\results.txt
    • route print >> C:\results.txt
    • ping 127.0.0.1 >> C:\results.txt
    • ping google.com >> C:\results.txt
    • ping 209.85.171.100 >> C:\results.txt
  • Once the above commands have completed, navigate to your C: drive and open the text file results.txt -- please copy/paste the contents of this file into your next response.
Thanks,
- Dan

Thanks Dan,
That worked on laptop #1. I had been in that menu a dozen times and just could not remember how to change TCP/IP properties. I remember resetting this when working on the WAP so that the machines would be on the same subnet, right? But in the case of the other laptop, I accessed the WAP through a router and did not manually reset the TCP/IP. I will look at the other laptop later today but I am curious how I managed to f^%# up the settings of the NIC just by browsing the address of the WAP to get into the menu?
