At&t wireless router with dsl modem security types do not match

[confusedhusband]

Hello,
My wife's laptop will disconnect from our ATT Netscape router/dsl modem. The error we get is that the "security types do not match" ultimately we have to reboot the router and then her laptop will connect for a while. (we do not have this problem with any other devices that use this wifi connection...any thoughts?)

The computers that connect , do they all have the same OS on them ?

The security key that you make when you set up the routers security can usually be done with several different encryption methods. WEP , WPA and WPA2 are three os them and there are others but they are mostly for buisness and enterprise situations.

Does your Wifes laptop have an older OS ?
