Windows 7 Dial Up Internet Connection Sharing Error:Access Type No Internet Access With Yellow Triangle Alert

[abbeyonline]

Hi, i am a newbie when it comes to Windows networking particularly Internet Connection Sharing (ICS). A week ago i turned my Win 7 HP Laptop into wireless router which is on EVDO 3G dial up using the windows (ICS) to connect my second Win 7 Dell laptop which was successful.


Unfortunately, i ran out of data and now that i have recharged my Evdo 3G dial up modem hoping to continue browsing on both laptops, the Dell laptop which in this case is the client is showing connection signal but each time i tried to connect, this error will come up- Access type : No Internet access along with the dreaded yellow triangle alert on the system tray.

Although when i plug the modem directly to the Dell laptop, it does browse smoothly.


I have Google and read almost everything concerning this online including this forum but i have not come across a solution that is peculiar to mine.

Please what can i do to resolve this challenge?

PS: I have disabled both Windows firewall and AVG still the lack of connection still remains.

It seems like you are facing an issue with Internet Connection Sharing (ICS) on your Windows network setup. The error you are encountering, where the client laptop shows "Access type: No Internet access" with a yellow triangle alert, can be frustrating. Let's try to troubleshoot this issue step by step:

Troubleshooting Steps for ICS Issue:​

1. Disable and Re-enable ICS:
   • Disable ICS on your primary (host) laptop and then re-enable it.
   []Reset Network Settings on Client Laptop:
   • On the Dell laptop (client), try resetting the network settings. You can do this by:
     • Press Win + R, type cmd, and press Enter.
     • In the Command Prompt, type the following commands:

        ipconfig /release ipconfig /renew

   []Check Network Adapter Settings:
   • Ensure that the network adapter settings on both laptops are correct. The client laptop should be set to obtain an IP address automatically via DHCP.
   []Run Network Troubleshooter:
   • On the Dell laptop, run the built-in Windows Network Troubleshooter. This tool can often identify and fix common network issues.
   []Check DHCP Service:
   • Ensure that the DHCP service is running on the host laptop. The DHCP service assigns IP addresses to devices on the network.
   []Update Network Drivers:
   • Make sure that the network drivers on both laptops are up to date. Outdated drivers can sometimes cause connectivity issues.
   []Static IP Configuration:
   • If DHCP is not working correctly, you can try configuring static IP addresses on both laptops. Make sure the IP addresses are in the same subnet.
   []Check Firewall Settings:
   • Even though you mentioned disabling the Windows firewall, double-check that there are no third-party firewall applications blocking the connection.
   []Antivirus Software Settings:
   • Some antivirus software can also interfere with network connections. Ensure that your antivirus software is not blocking the network traffic.
2. Restart Both Laptops:
   • Sometimes a simple restart can resolve network connectivity issues. Reboot both laptops after making any changes.

     Additional Tips:​

     • Ensure that the network cable between the host and client laptop is securely connected.
     • Verify that the network sharing settings are correctly configured on the host laptop.
     By following these steps and checking these settings, you should be able to resolve the ICS issue and restore Internet access to your Dell laptop through the host laptop's EVDO 3G dial-up connection.
