Windows 7 Internet browsing problem

[Ananda Kurade]

Hi All,

In my pc i have two nic as one of them is configured with broadband modem and another one is configured to share internet to my laptop through one switch.

broadband modem >> nic 1 >>> internet is working fine.

Nic 2 >>> switch >>>> laptop >>>> can ping any site ( by ip or by name) >>> but unable to browse in browser.


Nic 1 >>>> DHCP configured ..... and shared with nic 2

Nic 2 >>>> manually configured and connected to swich.

switch >>>> laptop >>>> laptop nic is configured manually.

from laptop i can ping DNS or any site ip / name but when i open ie is taking long time and display connecting to site 74.125.236.48 (as i set my home page is google) on status bar and error display on screen that "internet explorer cannot display the webpage."

please help...

It seems like you are encountering an issue with your network setup where your laptop connected through NIC 2 via a switch is unable to browse the internet even though it can ping sites successfully. This type of issue typically arises due to misconfigurations in the network settings. Here are a few steps you can take to troubleshoot and potentially resolve the problem:

Troubleshooting Steps:​

1. Check Network Adapter Settings:
   • Verify that the IP configuration on NIC 2 and the laptop is correct. Ensure the subnet mask, gateway, and DNS settings are properly configured.
   []Verify Internet Connection:
   • Ensure that the broadband modem connected to NIC 1 has a stable internet connection. You can confirm this by checking if devices connected directly to NIC 1 can browse the internet.
   []Check Firewall and Security Software:
   • Temporarily disable any firewall or security software on the laptop to see if they are blocking internet access.
   []Flush DNS Cache:
   • Try flushing the DNS cache on the laptop to ensure that there are no DNS resolution issues.
   • Open a Command Prompt and enter the command: ipconfig /flushdns
   []Test Different Browser:
   • Try accessing the internet using a different web browser on the laptop to see if the issue is isolated to a specific browser.
   []Reset TCP/IP Stack:
   • Reset the TCP/IP stack on the laptop to clear any network configuration issues.
   • Open a Command Prompt with administrator privileges and enter the following commands:

     bash netsh int ip reset netsh winsock reset

   []Check Proxy Settings:
   • Make sure there are no proxy settings configured on the browser that may be interfering with the internet connection.
2. Verify Network Cabling:
   • Ensure that the cables connecting the switch, laptop, and NIC 2 are properly seated and functional.

     Further Assistance:​

     If after following these steps you still encounter issues, it might be beneficial to double-check the network configurations and troubleshoot any misconfigurations. Additionally, consider updating network drivers on both the laptop and the PC hosting the NICs. Feel free to provide more details or results after trying these steps for further assistance.
