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!

LAN & WLAN fail to work on Toshiba Satellite L20 173

Asked by steveholly in Windows Networking, Networking Hardware, Wireless Technologies

Tags: Toshiba, L20, WLAN, LAN, Atheros, Network Controller, Network, Wireless

Hi All

I have a strange issue on a Laptop (model above). The recovery CD installs and then on boot laptop blackscreens. I performed a fresh install of WinXP and installed all drivers from Toshiba website. All updates from MS incl SP3.

The issue I have is the LAN fails to function (driver looks fine in Device Manager) It shows a limited or no connectivity unless I enter a static IP address then although it shows connected I can't ping the router.

Also the WLAN fails to show wireless networks intermittently and when it does - refuses to connect to one - enter network code  and still shows as not connected. The original WLAN card was a Atheros.

The strangest part of all this is that if I insert into the USB port after installing drivers for it - a USB ethernet adapter this works fine, but also the LAN port and the WLAN connects immediately. Remove the USB Ethernet Adapter and the connection on LAN and WLAN is dropped immediately????

I have installed the OS 3 times now, tried different drivers for the LAN and WLAN from Toshiba and on the web. I have changed the WLAN card to an Intel Pro 2200BG to see if this had any effect - it didn't. There is no security software installed.

This has stumped me! Does anyone have any ideas?
