Hello. I ve got dual boot vista x64 and win 7 x64 on my computer. I have DWL DLINK 510 wirelles card and on other side at my friend router TP link.
It connects fine but when i try to surf the net it just dosnt work. In event viewer i get this msg :
Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x001E58A0FAAC. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.

So far i have tried almost everything i googled about this and the net just dosnt work....
In vista it works just fine, but i cant get it to work in windows 7....
Any ideas how to resolve this problem?

Thanks in advance guys!

It seems like you're facing an issue with your wireless connection on Windows 7, specifically with obtaining an IP address from the DHCP server. This can be a common issue with network connectivity. Here are some steps you can take to troubleshoot and potentially resolve the problem:

### Troubleshooting Steps:

1. Check Network Settings:
- Make sure that the wireless card is enabled and properly configured in Windows 7.
- Ensure that the network settings, including TCP/IP configurations and DHCP settings, are correctly set up.

2. Restart DHCP Client Service:
- Sometimes restarting the DHCP Client service can help resolve DHCP-related issues.
- Press Win + R, type services.msc, and press Enter.
- Find the "DHCP Client" service, right-click on it, and select "Restart."

3. Release and Renew IP Address:
- You can release and renew the IP address using the Command Prompt.
- Open Command Prompt as an administrator and run the following commands:
       ipconfig /release
       ipconfig /renew

4. Check Network Drivers:
- Ensure that you have the latest drivers for your wireless card installed. Outdated drivers can sometimes cause connectivity issues.
- Visit the manufacturer's website to download and install the latest drivers for Windows 7.

5. Disable IPv6:
- Temporarily disable IPv6 to see if that resolves the issue.
- Go to Network and Sharing Center > Change adapter settings.
- Right-click on your wireless network connection, go to Properties, and uncheck the box next to Internet Protocol Version 6 (TCP/IPv6).

6. Static IP Configuration:
- If DHCP is causing issues, you can try configuring a static IP address for your network connection.
- Manually assign an IP address, subnet mask, default gateway, and DNS servers.

7. Check Firewall and Antivirus Software:
- Sometimes security software can interfere with network connections. Temporarily disable the firewall and antivirus to check if they are causing the issue.

8. Reset Network Stack:
- You can reset the TCP/IP stack in Windows 7, which can help resolve network connectivity problems.
- Open Command Prompt as an administrator and run:
       netsh int ip reset

After trying these steps, restart your computer and see if the issue has been resolved. If the problem persists, please provide more details about your network setup so we can further assist you.
