I have a desktop connected to a Belkin wireless modem/router and my wife has a laptop with a Belkin54g adapter. It has been running successfully for quite a while until recently I changed the security on the router to WPA from WEP. I now find that I can connect to the Belkin adapter but not the internet. Sorry, things have changed. I switched my wifes laptop off and on again and now cannot get connected to the adapter. The little screens on the taskbar states there are networks available. I think I need to start from scratch. Can anyone help please?
If you've change the encryption in the router from WEP to WPA, then you need to delete the existing wireless "profiles" (which Windows has saved so that you can connect automatically) and go through the procedure to "Connect" again. You will be prompted for the WPA key and, once connected, a new profile will be saved.
