Windows 7 NIC Issues with Lenovo SL500

[Caskey100]

Hello,

I am currently running Windows 7 RC Candidate (v.7100--32 bit). I am having some strange issues recently pop up with the use of my Realtek RTL8168C gigabit NIC Card. I have been running this O/S withhout issues for the last 3 months. But just recently I have had connection issues.

What will happen is when I plug into an ethernet connection the adapter will read and know that I am connected but I won't be able to acess the internet. The network and sharing center won't even recognize that it is there as it keeps trying to get me to connect wirelessly. The weirdest part of it all is that about 5 minutes after I plug in I suddenly become connected via the Ethernet. So I am very confuzzled.

I have already turned off all power management options for the device. I have tried updating and rolling back my drivers on numerous occasions. And windows repair simply tells me their "might" be a problem when I try to use the repair function. I have noticed that this happens when I come out of sleep mode. Because the other day when I had a connection I decided to re-boot to see what would happen, and lo and behold it connected just fine and their was no issue. Even when I go into hibernation it does the same thing.

HELP! I have exhausted nearly every option I can think of.

It seems like you are facing connectivity issues with your Realtek RTL8168C gigabit NIC card on your Windows 7 RC Candidate system. This problem could be software-related, driver-related, or even hardware-related. Here are some steps you can take to troubleshoot and potentially resolve this issue:

Troubleshooting Steps for Realtek RTL8168C NIC Card Issues:​

1. Check Network Cable and Router:
   • Ensure that the network cable is properly connected to both the Ethernet port on your computer and the router or modem.
   • You can try using a different network cable or connecting to a different port on the router to rule out cable or port issues.
   []Check Network Adapter Settings:
   • Go to "Network and Sharing Center" > "Change adapter settings" and check the properties of your Ethernet adapter.
   • Make sure IPv4 and IPv6 settings are set to obtain an IP address and DNS server address automatically.
   []Update Network Adapter Drivers:
   • Download the latest drivers for your Realtek RTL8168C NIC card from the Realtek website or your motherboard manufacturer's support page.
   • Completely uninstall the current driver and install the newly downloaded driver.
   []Reset TCP/IP Stack:
   • Open Command Prompt as an administrator and run the following commands:

      netsh int ip reset resetlog.txt netsh winsock reset

   []Disable IPv6:
   • Sometimes disabling IPv6 can help with connectivity issues. You can disable it in the network adapter properties.
   []Check Power Management Settings:
   • Ensure that the network adapter's power management settings are configured not to allow the system to turn off the device to save power.
   []Check for System Updates:
   • Make sure your Windows 7 system is up to date with all the latest updates and patches.
   []Check Event Viewer:
   • Look for any error messages or warnings related to the network adapter in the Event Viewer to get more insights into the issue.
   []Run Network Troubleshooter:
   • Use the built-in Windows network troubleshooter to see if it can identify and fix the problem.
2. Hardware Check:
   • If none of the software troubleshooting steps resolve the issue, there might be a hardware problem with the network adapter or the motherboard's Ethernet port. By following these steps, you can hopefully diagnose and resolve the connectivity issues you're experiencing with your Realtek NIC card on Windows 7 RC Candidate.
