So, I want to add some cheap wi-fi to my network. I already have a wired router, and want to keep it. I found this gigabyte card here . What do you guys think of it? Better yet what would be better?(has to atleast have a external antena) I will be using it only for my PSP, and maybe catch a occasional open network. Also is it true that the PSP only uses wireless-B networks? Thanks in advance.
