Inspiron 640m Problems with Wireless Network Adaptor

I am continually having to resent my wireless adaptor and also run diagnostics to autmatically find IP settings.  This used to solve the problem.  But now when my computer disconnects from my router I have to manually connect the computer with a lead to solve the problem and then I can use wireless again.  I took my laptop abroad in January and thats when the problems first occured.

 

A send computer in my home is using the same Belkin Router with no problems

 

Any comments and suggestions will be greatly appreciated!!

 

Thank you

    What OS are you using, and what type of WNIC are you using? Along what type of network encryption are you using? I had this weird problem with my Inspiron 640m when I got it. I had an Intel 4965 A/G/N adapter. For some reason on Windows Vista I couldn't connect using WPA-TKIP encription/authentication with my 802.11b/g router. On Windows XP with the same laptop there wasn't a problem. Snap snap it would connect. I figured it out by using the "better" WPA-EAS encryption/authentication with Vista, and now it connects snap snap. Also make sure that the internet actually works, because if you're using Vista the icon might be show disconnect, but it actually works. This has been changed on Vista SP 1 which I'm currently running, the taskbar animation is much better at being real-time.

    Step 1: Connect your computer to your router with a wire.

    Step 2: Log into your router and then go to the Wireless section and select the Encryption method.

    Step 3: Your options should be WEP 64 or 128, and WPA-TKIP or AES. Change the current setting that you have to WPA-AES or WEP. WPA is better then WEP.

    Step 4: If you choose the WPA option configure it with AES and not TKIP. Finish your configuration and then log out of your router.

    Step 5: Go into your Control Panel then Network and Sharing and select "Manage my Wireless Networks" . Erase all the networks that you see.

    Step 6: Disconnect your wired connection to your router and let the wirelss radio find the your network.

    Step 7: Click on the wireless activity taskbar icon, and select the box that says "Wireless Networks Availabe" and then choose your network, and it will then analyze it and prompt your for you password. It should then connect.

    Using AES instead of TKIP seems to work much better on Vista. I used TKIP with Windows XP and never had any issues, but when I had Vista it was a constant problem. After changing it to AES on the wireless router it connects instantly. If this doesn't help you then there could be an issue with your radio. Uninstalling your driver for the wireless and then rebooting the machine and letting Windows Vista re-install seems to solve the issues with network connections.

    If the connection is sucessful go the the "Network and Sharing" on the control panel and you should be able to see a map of your wireless network. On the top right after the file sharing options, you should see a link that says "Customize" click on it and the a box pops up, click on the "Merge, Delete" button and erase any other networks other then the one that you're connected. If you click on the network name and the Delete button happens to light up, delete it. You should only have one network there.
