In my Dell D series , 610, 620, 820 , In Bios the wifi card is described, make model, etc. you can download a bios update from Dell America, if it don't show up,When In bios set wifi for factory default, be VERY aware of Fn+F2 option. Seems as if it LL2.4 loses it some times after up date. The Bcm command line script per torreydale all ways gets it back for me. I have a PCMICA ? card slot on all my Dells, and keep El Cheapo Wifi plug in cards in my bag they all ways work. Don't know about using a USB dongle. I have only one by belkin it does not work on any linux I have. I have some other Later model Dells spread out among my Gkids , no problems there Only the Broadcom Wifi boards have/given me problems Also one other thought may be time for new Bios Battery ?The folks here, are so nice I struggle and read the post and tutorials. , Never gone back to Windoze. Love being FREE! Hope I could help ?
