Another noob needing some help

Hi everyone,

I hope not to be flamed to death by asking this, but I couldn't find what I was looking for in the "How To -" section.

I'm sort of sure that I can't do what I'm trying to do, but i'll ask to make sure.

I have a Linksys WRT54G/GS running DD-WRT v23 SP1 Final (05/16/06) std.

I'm currently receiving my internet connection wirelessly to the router with a 24dB antenna and from the router I'm connecting to the my PC with a "normal" network cable.

Now, what I wanted to know is it's possible to connect to my PC to the router via my wireless card? Thus receiving my internet connection wireless and connect my pc to the same router wireless.

Will this be possible or will I need to get another router to do the job?

Sorry, I tried not to be a real noob in asking, but probably failed when I started this post

Thanks for the help in advance.
