I have a Dell Latitude D630 which I have never been able to get to connect to our home wireless network. In my many attempts to correct this I have now deleted the wireless setup under "Add/Remove programs" so that there is no longer any icons in Network Connections that refer to wireless. I've tried reloading drivers etc but nothing has worked, so I am now at a loss as to what to do to get it all back again - need some help here please. There is also a yellow question mark against Network controller in the device manager. If you plug a network cable into it then you get internet ok. Cheers Mike

The first obvious suggestion would be the switch for turning on laptop's wireless capability. Go to Dell Drivers and Downloads Support site and follow the online instruction to acquire your wireless network card driver http://support.dell.com/support/downloads/driverslist.aspx?os=WLH&catid=-1&dateid=-1&impid=-1&osl=EN&typeid=-1&formatid=-1&servicetag=&SystemID=Latitude+D630&hidos=WW1&hidlang=en&TabIndex=&scanSupported=False&scanConsent=False

ok thanks, I have downloaded the driver and everything looks as it was. I am now back to the original problem I had. The laptop can see our wireless network but when you go to connect to it and its asks for the network password, you cannot type in the box. It will allow random numbers but no letters, If you enter too many numbers it generates this error message - Checksum validation failed for the PIN entered.

Is this your home network and do you know the password set on the router's wifi settings? Match the security mode set on the network device(modem/router) to your network adapter. IF the router is set to WEP(AES) then your wireless card should also be set the same or what supports both. Other security mode are WPA, WPA2.
