Having trouble connecting to wireless - Complete newbie!

[flowers_fall]

I want to apologize if I thoroughly make an idiot of myself on here - believe me, I've searched all night for similar threads and either don't understand the instructions or find that my computer simply isn't the same! I've tried to gather as much information as I felt needed when people asked in other threads. Just use small words around me, I'm really *that* technologically inadequet. Why I bought a linux ubuntu computer is still a mystery!

Okay, so I'm having trouble connecting to my home's wireless internet, which is linksys. I can connect via wire just fine, but I want to access my built-in wireless card. How do I set up the wireless for this machine? Here's the info of what version of Ubuntu and about the card.

Ubuntu 8.04.1 \n \l

Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8101E PCI Express Fast Ethernet controller [10ec:8136] (rev 02)
Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g [14e4:4315] (rev 01)

What do I do with this information? Thank you so much again for reading this through! If I could transfer edible cookies through this computer, I totally would.

What have you tried so far? If you AP is using either WEP or WPA encryption, then you will need to configure you system with the passphrase and/or encryption key. I've used 8.04 with my Linksys AP without problems, but I don't remember which wireless chip set my Dell D600 laptop used at the time (my grandson has it now).
