The Optiplex that I use for a media streaming machine uses a 2.4 GHz dongle for wi-fi. I want to upgrade that to a dual-band dongle, but I've already bought three of them -- that supposedly support Linux -- and not one has been recognized by the computer. It just reports "no wi-fi device found."
If anyone here is using an Optiplex with a dual-band wi-fi dongle, could you please let me know what brand it is? I really don't want to buy a fourth one that the computer won't recognize. Thanks for any help with this.
