use a router in"client mode" or use pci card for a wireless desktop?

hey someone posted that i should use "A compatible router running DD-WRT in "client bridge" mode. E.g. Asus WL-520gU

Pro:

- driver free, OS-independent, independently connected, supports multiple devices, not expensive, easy to use and maintain once set up, positionable for best reception, re-purposable, also supports repeating and other wacky features

Con:

- complex initial setup, requires working wired LAN port, size / portability "

Can you give me more information on how to do this? How would I set it up? I was orginally going to go with a wireless n draft pci adapter but this seems like a better idea. I have a linksys wireless 54g router that is set up with internet and gives wifi to 3 other laptops and a ps3.

The thing is, is that I am using a desktop and I need wifi. Do you still think I should do this router idea in client mode instead of using a pci draft n wireless adapter?

Thanks man!

and what is this DD-WRT technogoly?

would it be better to go with SMC SMCWEB-N or ASUS WL-520gU IEEE 802.3/3u/3x, IEEE 802.11b/g Wireless Router. Price not really an issue. Also I am using vista 64

thanks
