I have a Dual Boot on my laptop. I have windows 7 Rc and Windows Vista Basic. I just installed windows Vista and got everything working except my Wireless Card. When I boot into Windows 7 it sees it and uses it with no problem. But when I boot into windows Vista it cant see it. It also says that there is a problem with my network controller the problem is there is no driver but it cant find one online. When i use everest it says the unknown network controller id is pci/VEN_14E4&DEV_4315&SUBSYS_E00310 5B&REV_01 when i look it up it comes up as the broadcom adapter. I have installed the correct drivers for my device a few times and i have uninstalled the device and tried to reinstall it but it wont recognize the drivers as the right ones and i verified they were right because i looked them up on my other boot.

Sorry I forgot to tell you it is a Acer Aspire 5515

I suspect your choice of software is lying to you. Your laptop has Realtek wired ethernet, and one of three different possible wireless network adapters (Atheros, Foxconn, or Ralink) according to Acer themselves. Atheros: http://global-download.acer.com/GDF... Foxconn: http://global-download.acer.com/GDF... Ralink: http://global-download.acer.com/GDF... I've never actually "met" a Broadcom wifi card...tons of wired ones though. It's possible Broadcom and one of the above brands work together in a "brand engineering" scheme, so you might really have a Broadcom card sold under a different brand, but let's go with what Acer says first and foremost unless you've had the card replaced with a different one. Download and run Unknown Devices (http://www.halfdone.com/Development/UnknownDevices/). It might identify your card, at least brand name hopefully.

Dude I worked so hard on this problem and it never occured to me that broadcom would work with someone else for the wireless card. I was the Foxcon driver. You have no idea how much you helped. The problem is solved and it was thanks to you and that unknown devices program every other utility i ran just told me it was a broadcom device that was the only one that said it was also a foxcon device. thankyou.

Glad I could help :) When in doubt with any sort of laptop driver issues, you should always visit the manufacturer website and lookup the model number. Even if they don't offer drivers for your version of your OS, they will often reveal brands and model numbers which can be helpful in tracking down the right version.

yeah i went there first but none of the drivers were for a broadcom device that i could tell it wasnt until you pointed out that one of the drivers might be for a collaboration between broadcom and someone else. Thanks again.
