Go into Device Manager and open the Network Adapters. Right click the wired/Ethernet adapter and disable it. This will force Windows to use the wireless adapter. Make sure the wireless adapter is active.
BTW. Letting Windows (Wireless Zero) administer your wireless connection is preferred.
Do you have encryption enabled such as WPA? And if so, have you set the password/key on the laptop to the correct entry? Are you broadcasting SSID from the router to let the laptop find it? And back to the WPA password.
My son has a Futjitsu Lifebook E-8410 laptop (purchased 2007) loaded with Windows XP Pro. He has always successfully connected to the wireless network in my home, however, this time we are having problems.
For reasons I won't go into here, we had just used Windows Update to instal IE 8 and SP 3 on his laptop (yes, I know that should have been done ages ago). It was immediately after doing that, that we had difficulty connecting the laptop to the internet. (Note that my own desktop computer is having no difficulty in making the wireless connection.)
Although not a computer expert by any stretch of the imagination, I have managed to at least get to the point where the laptop is no longer using "Windows" to "manage WiFi", and I now have "Intel PROSet/Wireless" managing the WiFi. Everything on the laptop now indicates that the laptop is connected to the internet, and that the signal quality is "excellent". As well, I phoned the internet provider and they confirm that they can "see" the laptop inside my house.
However, we still cannot access the internet with the laptop. The message is that "A network cable is unplugged". However, despite much research, I cannot seem to determine how to "plug the network cable back in".
I would very much appreciate it if someone could provide me with some suggestions on what I can try to plug the network cable back in. Please note that I am not very sophisticated when it comes to computers, so any suggestions have to be in very simple language.
If you need any further information about my hardware/software, please let me know.
Thanks so very much for any assistance you can provide.
