No need to be harsh. A chipset and a brand name are not the same thing. Linksys (the brand name) made a ton of these cards under model number WMP54g and they all have different chipsets. Wonderfully confusing, isn't it?
So he may have the Broadcom, or the Realtek (Ralink) or something else. To get your chipset, Artic Shadow, copy the Hardware ID in the Device Manager>>Properties>>Details. Google it and you should see people talking about it along with it's chipset name. This will hopefully lead to a working driver
FYI the Windows driver for mine (dated 6/2010 does not work.)
Also, the conflicts others are talking about are most likely because they are dealing with a Realtek/Ralink chipset. Realtek is in everything, and unfortunately doesn't play nice with iteself. So Ram, Sound cards, and Video Cards with any Realtek chipsets will often get uninstalled or will refuse to allow your wireless card. (Trust me, I am stearing clear of Realtek, Ralink and ATI from now on. AMD owns them now, but they're just trying to clean up the mess... hopefully!)
My Wifi hardware ID is PCI\VEN_1814&DEV_0301&CC_0280
I have Windows 7-32bit/Realtek onboard sound/ATI Radion with Realtek HDMI sound/3.0Gb ram (Realtek?)/ Intel based cpu/Dell mobo.
So short story, just get a new card for $20 or less because it's not worth it with this one. It will keep doing this even after you get it working.
(I got the TP-link USB 802.11n from NewEgg, and made sure it is not Realek. It's an Atheros chipset.)
Long story... see my post here. Driver attached. Ralink Wireless LAN Card V2 HELP!
BTW a lot of my problems cleared up when i updated my chipset drivers
for my Motherboard. Especially if you installed a plain copy of Windows onto an OEM system, it might help. In addition I installed the "Chipset software" which updated my inf files from the generic versions and helped smooth some hardware conflicts. I went to Intel's website.... And of course, *sigh*, Windows updates.
