I am look to purchase an 802.11b PCI card for use in a secondary linux machine likely running Fedora. I currently have a DWL-520+ which is nearly impossible to get working in linux due to its chipset. It seems that the Prism based cards have the highest support, but I am having difficulty finding the cards that have this since most product descriptions forgo information about the chipsets. Could someone just provide a link or two for me to some decently priced cards (preferably on newegg or amazon)? I am looking to spend $40 or under, and I would really like if it has the option for an external antenna. Thank you very much for the assistance.
