Need to find the wireless radio on my computer, and the "switch" to turn it off/on. can you help me??

There is usually a button on wireless routers that puts them in to "discover" mode. You did not mention the wireless router you have so you'll need to locate the button on it by a visually looking for it or reading the manual. Once it's in this mode, you extender should begin to communicate with it and vice versa.
Although not a requiredment...it is highly recommended to have the extender and your wireless router from the same manufacturer. Mixing and matching will probably lead to miscommunications of both devices.

If there is no physical switch, look at the top of your keyboard. You should be looking at the "F" keys ( F!, F2, F3 etc or the number keys (1-2-3-4-5-etc) You should see a little symbol which looks kind of like this ))) (It will be 3 ('s starting small and getting progressively bigger) this is your wireless switch.....hold down the ctrl key and hit this button (Depending on the model, you might have to hold down ctrl, alt or shift) I run into this all of the time....Your manual should give you this info. If you dont have one, go to dells website and download one...it's free. Hope this helps
