    Hi, all, my notebook is Fujitsu LH532, I have upgraded the lan card to Broadcom BCM94352HMB, I am using the Netgear R6300 v2, with win 8.1.
    Before the upgrade, for lan network, the speedtest for dowload >800m, for upload >800m, but after the upgrade, the lan network is only 400m for dl, and 800m for upload, and for wifi, is it very very low, only 130m for dl and 200m for upload.
    I have updated the 8.1 driver of Broadcom BCM94352HMB and for the lan Realtek PCIe GBE Family Controller.
    What's the problem? The driver's problems? or the setting of router?

    It could also be a problem somewhere else than the drivers/router and your internet speed dropped for some other reason.

    It could be the drivers, so you could try reverting to the previous version you had. You could also try power cycling the router.

    The BCM94352 is one of the wors WLAN cards I have ever used. It came preinstalled in my Alienware 18, frequent disconnections, high ping rates, and very slow performance. I upgraded it with an Intel AC7260 (revised edition) and have never been happier.

    As for the driver, you can try the Alienware drivers they're for that same WLAN Card, when you run the installer, don't install but choose extract to folder instead then run the installer from there:

    Windows 7: Broadcom BCM4352 Wireless Bluetooth 4.0 v6.5.1 Driver = http://downloads.dell.com/FOLDER01978006M/2/Communications_Driver_2YP98_WN_6.5.1_A02.EXE

    Windows 8.1: Broadcom BCM4352 Wireless Bluetooth 4.0 v12.0 Driver = http://downloads.dell.com/FOLDER01976461M/2/Communications_Driver_VWT97_WN_12.0_A02.EXE

    thx~~~
    I think it is the problem of driver. I have tried different sources of driver, Leonov, Boardcom, and Asus, where Asus gives the faster speed, with 250M dl and 250M upload, others are only half of the speed

    I will try and give feedback here~~

    tested:
    the driver of dell also give a bad performance like Lenovo, while Asus is the best one~
