The VPN Troubleshooter was developed to assist users facing technical problem accessing their email via the remote access service including overseas connection via iPass service (applicable to Basic Checks section only). The VPN Troubleshooter included buttons to detect known network connectivity issues. Users are also able to self resolve problems with the help of this program. To further diagnose the reported issue, some information from the generated log will be required.

How to use the Troubleshooter Program
If you are not able to access the Internet via the hotel broadband service or home broadband:
Click the "Detect IP" button to determine if your notebook is assigned with a valid IP Address from the network (please refer to the Function of each buttons for more information). Click the "Renew IP" button to request a new IP address from the network when necessary (or restart the notebook).
If you are still not able to connect to the VPN:
Click the "Ping test" and the "Telnet test" buttons to further diagnose the root cause. A firewall might be preventing your notebook from connecting to the Singapore Government Network.
If you have connected and login to the VPN client but still not able to surf the Internet:
Click the "Check Internet" button to verify if your notebook has successfully secured with Singapore Government Network. Do ensure the Internet Explorer Proxy setting is enabled before you click at the above-mentioned button.
Can you browse the Internet without connecting to VPN client?
Yes, you may access the Internet without connecting to VPN. Click the "Toggle" button to set the proxy off.

(b) If the assigned IP Address start with 127.0.0.1 or 169.*.*.*, check to ensure the network cable connecting to your notebook is secured.
