Windows 7 Win 7 Pro x64 slow to set up network connection

[ironstone]

I have Windows 7 64-bit connecting to a hybrid Windows/samba network.

On boot, Win7 takes 1 - 2 minutes to negotiate a DHCP lease; set to a static, it takes about the same amount of time to connect. Other Vista and XP PCs connect in seconds. I have tried:

• Replacing the switch
• Enabling Spanning Tree Protocol and Fastport on the switch
• Replacing the DHCP server/gateway
• Updating the Win7 NIC drivers
• Selectively disabling components in startup (removing the Nero components helped a bit)
• Disabling IPv6 and Link Layer Topology drivers in Local Area Connection properties
• Changing from one firewall (Forticlient) to another (COMODO) - both 64-bit

I've searched high and low for other solutions, but no success. Any advice would be appreciated.

It seems like you've already tried several troubleshooting steps to address the slow network connection issue on your Windows 7 64-bit computer. Since you've exhausted quite a few options, let's delve deeper into some potential solutions: 1. Disable Autotuning: Windows uses a feature called Autotuning to improve network performance. However, in some cases, it can lead to connectivity issues. You can disable it using the Command Prompt:

shell netsh int tcp set global autotuninglevel=disabled

2. Disable Large Send Offload (LSO): Large Send Offload is a feature that allows the TCP/IP stack to build a larger packet. Sometimes, this feature can cause network issues. To disable LSO: - Go to Device Manager. - Locate your network adapter, right-click, and select Properties. - Go to the Advanced tab and disable Large Send Offload. 3. Check Network Card Power Settings: Sometimes, power-saving settings can affect network performance. Ensure that your network card is not set to power-saving mode. Go to Device Manager, right-click on your network adapter, and check the Power Management tab. 4. Check for Malware or Background Processes: Malware or resource-intensive background processes can also slow down network connectivity. Run a full system scan using reputable antivirus software and check for any unwanted processes running in the background. 5. Reset TCP/IP Stack: You can reset the TCP/IP stack using the Command Prompt:

shell netsh int ip reset

6. Check Router/Firewall Settings: Ensure that your router or firewall settings are not causing any conflicts with the Windows 7 machine. Check for any specific settings that might be impacting network connectivity. 7. Network Adapter Settings: Verify that the network adapter settings are configured correctly. Check the Speed & Duplex settings in the network adapter properties and ensure they match your network infrastructure. Try these additional steps to see if they help resolve the slow network connectivity on your Windows 7 machine. Let me know if you need further assistance or if you notice any improvements after trying these suggestions.
