An old IBM laptop was connecting fine to a d-link di-624 router wirelessly. SSID was "default" and there was no encryption.
I changed the ssid and added wpa-psk. Then found out the laptop was old and used only WEP. so I changed wpa-psk to WEP.
When I tried to connect to the network, it never brought up the netork key dialog box -- instead, it said "Windows is unable to connect to the selected network". But if I tried to connect to nehbor's networks, it did ask me for the network key.
Then it began not to see any wireless networks at all, off and on. the signal strenght was high.
I dropped the firewall, and I removed encryptino from router. NO change.
So I installed a belkin usb wireless, it connected fine to the network. Until I added encryption back. THen no connect.
So I removed encryption and set the ssid back to "Default" nad uninstalled belkkin usb wireless. Now the laptop connects fine again.
But we want encryptoin, and to change the name.
Waht could be causing this?
