Wireless equipment and setup for Mac Book Pros

Question

I've recently bought a Mac Book Pro after having used PC's since the 80's. Like it so much, I ordered a second machine for my wife.
Question: Using my Linksys wireless router used originally with our PC's, I've made several attempts to wireless network the two Macs using our same DSL connection but have failed each time.
Can someone tell me what I need in terms of equipment and also where to find the instructions to set up both Macs via the wireless mode.
Apparently, I'm clueless.
Thank you.

Your Macs should work with the same wireless equipment as your Windows PCs.
But, in my experience, there have been some problems with some versions of OS X and some versions wireless router firmware - specifically in the area of WPA wireless security.
The first thing I would try is reconfiguring the Linksys to run an open network, with no security. If the MacBook Pro is able to connect correctly, reconfigure the Linksys with a new SSID (wireless network name) and enable WEP security. If that works correctly, reconfigure the Linksys with a new SSID and WPA2 security.
I suggest using different SSID's for these tests because the Mac saves information about the wireless connections based on the SSID; using different SSID's for the different security settings reduces the chance the Mac will get confused by the security changes.
