    Win 8.1

    Same problem here - please help


    I'm having the exactly same problem after updating to Win 8.1. After a few minutes my wired LAN connection goes "limited connectivity". I disabled the power saving option alread - no success. My laptop has a Broadcom NetLink Gigabit Ethernet adapter with Driver Version 15.6.1.2 from Jan 29th, 2013. I couldn't find a newer driver. A reboot typically helps but takes for ever.
    I'd appreciate any hint - this is really a very annoying problem.
    (Sorry for my bad english)
    Thank's in advance for any hint.

    Newer drivers are not always better For some strange reason the driver that Windows setup "likes" is actually a Vista driver. The problem has been fixed in my computer using the driver at this url http://dell.to/16nfwMF which is a Windows 7 driver.

    Thanks a lot for the link. I'll give it a try and keep you updated.
    This is a very frustrating problem. I need the internet connection because my CAD program requires a permanent connection to the license Server. I'm close to throw the laptop out of the window (5th floor).

    Hi. I had a problem with very slow network speeds after installing 8.1. In my case it was caused by the new version of Avast! 2014, which had to be installed for 8.1. Avast! automatically turned on a firewall. Since I already had a firewall running, a second one definitely slowed things down. I turned off the Avast! firewall and it turns out that 8.1 seems a lot faster than 8. I hope this helps someone.

    Avast 2014 seems to be causing a few problems, their sandboxing is very aggressive and stops a lot of legitimate apps installing. During my upgrade to 8.1 Avast just vanished!

    Also, as @seabass901 mentioned in another thread, try entering a DNS manually (I use Google's https://developers.google.com/speed/public-dns/ )

    Old Win7 driver seems to resolve the issue


    As suggested I went back to the old driver, which can be downloaded from above mentioned link from the Dell website. So I'm using now driver version 12.4.0.3 under Win 8.1 and this seems to fix the problem. I had no drop out any more for almost 2 days.
    Obviously newer is not always better

    Thanks a lot for the hint.

    This fixed my issue as well. I haven't dropped connectivity in a day.

    Windows xp - 8.1


    I also have the broadcom NIC driver issue. Same NIC hardware in a Dell Studio XPS. Ever since 8.1 the NIC will not stay connected to the network. It's like all traffic just stops. I have a good IP address, but the computer can not be ping'd at all. I am putting on the for mentioned driver to see if that helps.

    As BlackDisk posted elsewhere, this may fix your internet:

    Open a CMD prompt as an Administrator. It must be run as administrator. To do so as an administrator, right click on "CMD" in the Metro interface, and choose the run as administrator option at the bottom of the screen. If you work from the desktop or start menu, right click on the CMD shortcut and run as administrator.
    Type this: netsh winsock reset
    Press enter.
    Reboot your computer.
