I've read through the WifiDocs/WirelessCardsSupported page and I'm still a bit confused. There are a lot of devices where it says that it works 'out of the box' with different specific versions of Ubuntu. Anyway, I had a few questions, I was hoping someone could help me out with.
1.) If a piece of hardware works in an older version of Ubuntu, does Ubuntu guarantee that it will continue to work with future versions of Ubuntu?
2.) All of the items in the hardware doc have 'Make / Model / Chipset/Driver'. I know this might sound silly; but when I go shopping for a piece of hardware at a story like BestBuy or Circuit City, how can I know which Chipset that hardware will have? Will every LinkSys WUSB300N wireless usb adapter have the same chipset? Or can two boxes with the same name from the same manufacture have different chipsets? And if they can have different chipsets; how can I possibly know if what I am buying will work with Ubuntu?
3.) Is there any wireless network adapter that anyone here will personally guarantee? I hear people say things like get an 'Atheros' chipset or something, but I don't know what that means. I was hoping to buy a new wireless device today during lunch and BestBuy is the only computer store that is within driving distance. Is there anything someone could point me to on the BestBuy.com website that will 100% without-a-doubt work on the current version of Ubuntu and all future versions of Ubuntu?
Thanks in advance!
