I want to get a wireless network adapter for my laptop but I'm wondering about the quality of cheaper brands. I have a Linksys 802.11g wireless router so initially I wanted to get a Linksys card but they cost some money. I've seen other wireless cards go for much much cheaper but will there be any quality difference? If it's 54Mbps wouldn't it still be the same speed as a more expensive Linksys card? Suggestions, comments, concerns? Thanks.
