    No WLAN/NIC Broadcom 43142 Windows 7 Drivers for SVF15A18CXB


    Hi I'm having problems finding the proper windows 7 drivers for WLAN/NIC.
    System Specifications:
    Sony Vaio Fit 15.5" Laptop (SVF15A18CXB)
    Windows 7 Ultimate Edition x64

    The Network Controller is a Broadcom BCM43142
    Network Controller Hardware IDS:
    PCI\VEN_14E4&DEV_4365&SUBSYS_E071105B&REV_01
    PCI\VEN_14E4&DEV_4365&SUBSYS_E071105B
    PCI\VEN_14E4&DEV_4365&CC_028000
    PCI\VEN_14E4&DEV_4365&CC_0280

    Anyways the Situation:
    Last week I decided to downgrade from Debian Wheezy to Windows 7 (come at me windows fanboys )
    Anyways I set up a live USB with the necessary .ISO and got the Setup working-installed Windows
    7 Ultimate edition. I started a clean boot; therefore, obviously no drivers. So i hooked up my external HDD
    to my other computer and downloaded all the Sony drivers from their webpage (Sony eSupport - SVF15A18CXB - Support) and then off the external HDD installed them onto my PC. Started trouble shooting from then on when I could only get internet from the Ethernet cable. What happened is when installing the BCM wireless network adapter I would get the error "OS not supported". Searched the webs again to find that Lenovo had drivers for a similar make of the NIC. They also didn't work. I contacted Sony Support, they had no response.

    It's entirely possible there's no Win7 drivers for that Notebook/Laptop, not mentioned in that specifications page about it ever being available for Win7, shows only Win8. It may be too new for drivers to have been compiled for Win7.

    Legitimate excuses are always good, especially in a marriage or at work.

    Hey, first off all sorry for activing this thread. I have a vaio SVF15A18CXB with windows 10 Home x64, and i want to install windows 7 x64, i'd like to know if the buttom "ASSIST" will work and how did you install windows 7 on it? I still have the Sony's windows installation because i cant install windows by the classic method because my hd is GPT and i need to convert to MBRm and to do it, all partitions need to be formated (Recovery, Efi partition, C:) . Every time i need to format i used the buttom ASSIST and restored to the factory settting. But i see that there is something wrong with the OEM windows installation. Please answer me, i only found this thread talking about windows 7 on SVF15A18CXB and i googled in 3 languanges (english, portuguese and spanish)!

    All the drivers worked fine? What about the touchscreen?

    Thank you!
