You have a Dell Desktop and some NB that you want to connect Wirelessly. But is the Dell connected through a Wire to the Router.
If it is connected by wire and the other is by a Wireless connection you'll need to open the Control Panel of the Router and bridge the Wire and Wireless Networks together. If you don't do this they will remain isolated from each other.
As for the computer that you are connecting by the Wireless Connection did you follow the directions in the Users Manual and enter whatever security that the Wireless Access Point has? It is not enough to run the Setup Wizard and then show WiFi Connection being available you need to setup the computer in question to access that WiFi Connection by running the utility that comes with the OS or the Hardware it all depends on what you have there. You'll also need to enter the MAC, SSID WEP Key or whatever the WiFi Access point has so that you can actually connect to the WiFi Access Point. Or at the very least turn off this Security Feature in the WiFi Access Point and allow anyone within range to have unlimited Access to your Internal LAN. Not a great idea unless you are in the middle of nowhere without people close by.
So assuming that you have installed any hardware and the software Drivers for that Hardware you then need to setup the Wireless connection with the Wireless Connection Wizard in Windows or the Wireless Connection Manager if you are using the Intel WiFi Manager.
Then if one computer is wired to the Router and the other connects wirelessly you'll need to enter the Routers Control Panel through your Web Browser by typing in the HTTP address and entering the User Name & Password. Then once inside the Control Panel make the required changes and save the settings. If you have not checked the Firmware version of the Router do it before you do anything else and update as required then make whatever changes you need to.
This is all in the Users Manual that comes with the Linksys Device but that Manual may not be a printed paper it may be a PDF File that you need to read.
