|Can your boyfriend help you set this up?|
Once you give me the model of linksys [there are hundreds of linksys's] I can direct you to the manuals. But someone at your end will have to follow the manual to set up the wireless on the router as well as understand how to setup the wireless adapter on your pc/laptop for it to connect wirelessly to the router.
BTW if you don't understand terms just plug them into Google.
For example "cmd prompt" would lead you here
"Ipconfig" would lead you here
