ok first off, i assume you have service pack 2. you can check that by right clickin on the system icon in the control panel. on the general tab, it will tell you what service pack, if any, you have installed. if you dont have service pack 2, then post what you do have and ill revise my post
ok first, generate a WEP key or preferably a WPA key using one of the two pages that were in the post i linked to last time.
first, you have to encrypt the router. when you do that, it will disconnect you. to do that with a linksys router go to 192.168.1.1 (assuming u did not change the defaults), and login with ure username and password. to tell you the truth, you only need to type the password.
once you get in the router, click on the wireless link across the top. then on the sub navigation, click on wireless security. under security mode, select the type of security you want to use, i am going to assume that you are going to try WPA. also be aware that depending on which firmware you have from linksys your options will vary. i upgrade my firmware whenever they have new one, and seen the options change a lot. the one you want is WPA Personal which brings up options like WPA Algorithms, WPA shared key, and group key renewal. leave whatever value is in the group key renewal alone. what ure most concerned with is the shared key, and the Algorithms. supposedly, AES is better then tkip, so select aes. then paste in the key that you generated from the WPA web page. Click on save. the screen will say done and thats it, because at this point, you are disconnected since you are not using the key.
you can close your browser as you will no longer need it for this process. also be aware that if any of the settings dont seem to work, just go back into the router and change it and try something else. of course, after u save the encryption key, you will need to actually plug into the router via cat 5 to get into the control panel and make changes.
if you are using some other program that came with your wireless card then i wont be able to help you as they all vary greatly. like ArchAngel said tho, use the windows wireless configuration, sometimes called Wireless Zero Configuration, particularly in services.msc. IN ANY CASE, go to the control panel, make sure ure not in category view by clicking on the switch to classic view link on the left. If it says switch to category view, your are already in the right place and dont need to do anything.
Once you have a bunch of icons in the control panel, double click on network connections. there you should see your wireless adapter. right click on that icon to get the context menu. you will see something that says View available wireless networks. that will be handy in the future, but for now, click on properties. that will open up a properties box with 3 tabs at the top. click on the wireless network tab. in preferred networks you will probably see your router's SSID or name listed. if you dont click on add. if u do see it, double click on it. if new, you will need to type in your routers SSID at the top. there on the first tab, the association tab, you will see similar items that you saw while in your router. match them with whatever you set in your router, paste in the key that you pasted into your router, and click on ok. if you have multiple preferred networks listed, move yours to the top, or delete the un-needed ones. once you do that you should be able to connect easily. you can click on the view wireless networks button, and when that comes up, double click on your router name, and you should be off and running.
let me know if anything is unclear, or it does not match exatly because if hardware or software differences, and we shall see where we can go from there. . . good luck!
