The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

vpn works with one wireless card but not another on same computer

Asked by glentek in Virtual Private Networking (VPN), Wireless Network Cards & Adapters

I have a Dell Latitude D520 laptop computer with an internal 1390 wireless mini-card.  With it I can create a VPN connection to a remote network, and then I can ping network addresses there.  I also have a Belkin FSD7050 USB wireless adapter.  When I create the VPN connection to the remote network using the Belkin adapter, I can't ping any of the network addressess there. Using either NIC, I can access the internet directly (non-VPN).  Using either NIC, it appears that VPN connections are created (Cisco VPN Client creates icons in the tooltray).  However, when using the Belkin adapter, the VPN connection does not allow me to ping the network addresses on the remote network.

I have provided routing table information (netstat -rn) for each wireless NIC after the VPN connectiton has been established.  Note that I have changed parts of the the remote network IP addresses to 'aaa.bbb' for security reasons.  The only things I notice that look suspicious are lines 14 and 15 of the active routes.  It looks like the order of these 2 entries is reversed.  I'm not sure whether that is significant.  I have highlighted those lines with '***' on the left of each line.  Also, there are differences in the metric columne.  Again, I am not sure whether that is significant.  Everything else looks the same.

Any ideas of why this is happening and what I can do to get the VPN connection using the Belkin USB adapter?
