Unable to connect to a specific wireless network?

Question

My laptop is running on windows Vista basic. Core 2 Duo. Recently, it won't detect the wireless network it used to connect. However, it able to detect other networks. I have a mobile phone that has wireless capability and iPod touch both gets the signal and able to connect and browse but not with the laptop.

Nothing has been change on the location. These are the things I've done as far as troubleshooting is concerned.

=Powercycle the adsl/wireless router
=Restart the computer
=Switch off/on the wireless
=Remove the network on my wireless connection and manually added the network name and encryption key
=Disable and re-enable the wireless connection
=Check the wireless adapter on device manager. No yellow mark or something. I even updated the driver. And since the laptop is able to detect other networks that means the wireless adapter is working fine.
=Access the wireless router setup page. I tried to change the wireless channel and increase the range. It didn't help
=Change the name of the wireless network
=No mac filtering on the router
=Check EMI. Nothing has been added that may interfere the signal.

Now, I couldn't think of anything else that I've missed of doing it. Can anyone help me how to fix it? I badly need your technical help.

I would really appreciate it. Thanks in advance!

Answer 1

Several thoughts come to mind, what security software? There are a few times that some AV's / Internet Security Packages have caused this issue. You might just disable the security / AV to see if it does then connnect. One other thing that you might try is just changing the security code to see what occurs. Some drivers just simply don't like some WPA/WPA2 coding so switch to WEP and see if you connect. For tests you can even disable security. Be sure the SSID is unique and there are no other AP's with the same SSID within range.



You can also assign a static IP address on the adapter, just to see if it connects. Sometimes I have had DHCP just simply not work with some routers / wireless card combo's. (You may need to update the OS system as well as the wireless drivers.)



Other than those, you appear to have done all the things I would have.

Answer 2

If your laptop can pick other networks but not yours then your network down or not properly configured.

Maybe your network server or DNS is not applicable with your laptop or maybe your firewall is blocking your connection.
