new to wireless

Hi, I hope you can help me avoid any problems! Here comes my new HP Pavillion Notebook DV5020US. The wireless config. says this: Enhanced wireless: SpeedBooster technology enhances the built-in 802.11g/b wireless, providing improved performance and efficient data transmission.

- I got it at Circuit City, which threw in a D-Link Wireless G Router. (Dl-524)

I currently have a Hp Pavillion a340n desktop as my home computer and it's hooked to a sprint DSL realtek router RTL8139 that has an ethernet port though i think that's how my current dsl is hooked up. I have had no problems with my dsl connection and would love to keep it that way! I got the laptop mostly for use at home and would like it to be able to access the desktop, but most importantly share the dsl connection.

unfortunately, I'm unfamiliar with wireless and probably don't really understand it, so I apologize for any dumb questions.

Question #1- is the notebook out of the box compatible with the D-link Router or do I need a wireless adapter (that would be lame)?

Question #2- is there any way I can keep the desktop/dsl connection hard wired, so as not to disturb anything? And just the laptop have the wireless connection?

Any other tips or advice would be welcome.

I would love to hear from others that might have a similar set up.

Thanks!

Ami
