Hi Artbeats8
I would agree with MC_K7, Inspiron 6000 normally comes with the following wireless option- Intel Pro Wireless 2100 / Intel Pro Wireless 2915 / Dell Wireless 1350 / Dell Wireless 1450.
First ensure it’s enabled in the BIOS by tapping F2 while turning on the PC. Next make sure the wireless radio is turned on (Fn + F2), Also download & install the latest drivers from the dell support page.
