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!

Vista laptop (sometimes) won't connect to the internet

Asked by InteractiveMind in Miscellaneous Networking, Windows Networking

Hello,

Here's the situation:

* We have a router with several laptops connecting wirelessly.
* Everything has worked great over the past year.
* Over the past couple of weeks however, I (but no one else) have been having intermittent problems;
* the network claims to connect to the network (an 'unidentified network'), but there's no internet.
* Then again, some days it works fine (like right now). Occasionally a reboot fixes it, and other times it sometimes randomly connects on its own accord.
* My laptop is a 1 year old Compaq with Vista Home Premium.
* By the looks of the ipconfig/all output (see below), it's not connecting properly...
* It's certainly not a signal problem,
* and I don't have a firewall.
* A couple of days before this problem started, everyone was unable to connect to the network - it claimed that the security settings had changed (though they hadn't). So we had to delete and reconnect to the network to fix that. (I'm doubtful this is related though, as no one else is now having my problem.)


Any ideas?

Thanks in advance!
