  1. Hi everyone, I have a emachine D443 Laptop and I have just recently formatted and installed a new Windows 7 32 Bit Operating system. After installing the chip set driver and bios driver all other drivers I installed worked except for the wifi adapter, during installation of the wifi adapter an error saying "the device may not be present or could have been ejected/unplugged from the system". I have been searching for a solution ever since but have never found one. I even tried driverindetifier.com but witj no success. Help please. I can connect with LAN though.

    Well, the good news is the adapter is there and being detected

    The WEIRD news.. dxdiag says you have an Acer??? But more importantly, the Network Controller in your problem report is a Broadcom adapter. That's why non-of the D443 wifi drivers will work. (none of them are for Broadcom)

    Before looking for a Broadcom driver for you, can you double check your model number? Does Acer make any sense?

    Yes the dxdiag says I have an ACER. If you are asking for the model number of my Laptop it says underneath it is emachine D443 series model number: ZQQ. It also says there that this is a product of Acer Inc.

    Here is the link to the support site https://support.gateway.com/us/en/emac/product/default.aspx?tab=1&modelId=3744

    Hmm... seems very similar hardware to E443. Same makers for LAN, VGA, etc. Try the Broadcom wifi driver for the E443. Click HERE

    Check your vendor site as Cobalt suggested for the correct drivers
    > Your Ethernet connection is Atheros
    > Your Wifi is Broadcomm

    You need to make sure that the motherboards INF chipset drivers are installed. Are there any yellow (!) in the device manager?

    Have you tried scanning your pc to find out which drivers you have got or are missing?
    I have used this one for many years which has always proven to be accurate.
    If nothing else it will tell you what is actually on the motherboard.
    https://www.drivereasy.com/
    It is a 'paid for' program but if you scroll down about 5 screens, you will find a chart with 3 versions, one is the free version.
    The catch is the download of the drivers is VERY SLOW, but you can get the drivers from other places, once you know the correct information about your pc.

    Hi wilven, Does your 'Device manager' show any yellow warnings?
    Have you tried the program 'drivereasy' ;
    https://www.drivereasy.com/
    Can you use a cable to connect your router to your pc? Does that make a connection to the internet?
