Windows 7 Laptops drop or cant connect to network netbook can plz help

[sicex]

Like the title says our home network is aparantly running fine via wifi but the laptops in our house hold are having issues. First all we have called in a technician to solve this issue before but it was temporary. the desktop the modem is directly connected to says it has a connection of 100mbps and laptops that cannot connect to internet say 48-54mbps. The laptops run Windows 7 home premium and windows 7 ultimate. Desktop runs vista netbook runs win 7 starter. the netbook when connected says 18mbps and runs fine smoth and quick on the web but the laptops can take up to an hour just to download a few kilobytes and its rediculous that it takes me 5minutes to have a 50% chance to load google homepage. There are times when it will randomly jump in connectivity IE the page loads right away likeit should. I have run cmd as admin and run ping 4.2.2.2 to get varying results. i have had as good as 52ms and as worse as either 1700ms with 75% loss and to the point of 100% loss in a space of the few minutes it took me to run it. I have run spyware doctor malwarebytes norton and avira antivirus to find a few things but that is all and have them repaired. This has not fixed our issue and would like any help or advice because this is only a recent issue and it still runs perfectly normal on the netbook D: thanks in advance'

It seems like you are facing connectivity issues with your laptops on the home network despite the network appearing to be fine. Here are some steps you can take to troubleshoot and potentially resolve the issue:

Troubleshooting Steps:​

1. Check Network Adapter Settings:
   • Ensure that the network adapters on the laptops are configured correctly. Check the settings for the network adapter, including IP configuration (DHCP or Static), DNS settings, and gateway settings.
   []Update Network Drivers:
   • Make sure the network drivers on the laptops are up to date. Outdated drivers can sometimes cause connectivity problems. You can update the drivers through the Device Manager in Windows.
   []Check Firewall and Antivirus:
   • Sometimes, overzealous firewall or antivirus settings can block internet access. Temporarily disable your firewall and antivirus software to see if it resolves the issue.
   []Reset TCP/IP Stack:
   • You can try resetting the TCP/IP stack on the laptops to refresh the network settings. Open a Command Prompt as an administrator and run the following commands:

      netsh int ip reset netsh winsock reset

   []Flush DNS Cache:
   • Clearing the DNS cache can help resolve DNS-related issues. Run the following command in Command Prompt:

      ipconfig /flushdns

   []Check Hosts File:
   • Ensure that there are no incorrect entries in the hosts file that might be blocking access to certain websites. The hosts file is located at C:\Windows\System32\drivers\etc\hosts.
   []Check Router Settings:
   • Log in to your router's admin panel and check for any settings that could be affecting connectivity, such as MAC address filtering or IP address conflicts.
2. Run Network Troubleshooter:
   • Windows has a built-in Network Troubleshooter that can diagnose and resolve common network problems. You can access it by right-clicking the network icon in the system tray.

     Additional Recommendations:​

     • Consider upgrading the laptops to a more secure and supported operating system as Windows 7 has reached its end of life.
     • Check for any background processes or applications that might be consuming network bandwidth unnecessarily.
     • Restart your router and modem to ensure they are functioning correctly.
     By following these steps, you should be able to isolate and potentially resolve the connectivity issues on your laptops. If the issue persists, you may need to consider further diagnostics or consult with a professional IT technician for assistance.
