    I installed a genuine Windows 7 Ultimate on my recently bought i7 15" Macbook Pro and am facing some problems on network connectivity.

    The problem I have is on the connection instability. When I use internet connection such as playing games or watching Youtube videos but browsing, it constantly loses connection stealthily or even drops.

    So that any experts can really help me with enough information they can get from me, I did a test myself and I'm sure it will help you to help me.

    Here is what is happening:

    Closing the page is done by myself, but the video was left there until it reaches the end.
    My local IP address is in case anyone wonders from that image.

    To ensure this is not affected by any software, I formatted the computer and only installed Firefox and Adobe Flash Player. The problem still arose.

    I could have been the driver problem, but I updated with different versions. This is happening in both wireless and wired cable.

    What I can best guess is that it is the router.
    I have 7 PC's connected to the router, but I tried to turn them all off except for the new laptop. I had no luck. Resetting the router or unplug-plugging the power didn't not do much as well.

    I've done a lot of things that I can do myself to solve this issue but I think I reached my limitation. I need people's help.

    Here is the new laptop's spec.
    Intel i7 M620 (4 CPUs) 2.7GHz
    4.00GB RAM
    330M GT 512MB / DX 11.0
    Windows Ultimate 32-bit

    Network adapter
    Ethernet: Broadcom NetXtreme Gigabit Ethernet
    Wireless: Broadcom 802.11n Network Adapter

    ISP speed test:
    Download speed: 9.90Mb/s
    Upload speed: 1.84Mb/s

    It happens on wired/wireless at home, work or any WiFi spot.

    I'm really frustrated and the technical support from Apple wasn't able to help me.
    It would be really great if anyone can help.
    Thank you.

    Although you might not be a help it will be still great if anyone who installed Windows 7 on their i7 Macbook Pro can answer if they are having any problems like this or not.

    I have Windows 7 Home Premium installed on my 15'' i7 Macbook Pro. I haven't noticed any network related issues, though, I haven't been paying very close attention.

    I guess it's just me then...
    I'm not sure what's happening with mine.

    Had similar issues when I upgraded my PC to Win7, connection was dropping every few minutes.

    Device manager confirmed drivers were up to date for the NIC, but it still kept happening. I kept having to disable the connection and allow repair to run to get the connection back up again, just to lose it again 5 minutes later

    Eventually I went to my NIC card manufacturers website, downloaded the latest drivers, installed, rebooted and it has never dropped connection on me again.

    How does it run in OS X? If fine, then probably your Windows drivers ;)

    Mac Pro 15 inch i7 - Problem fixed!


    I tried this:
    and this...

    But did not work for me.

    So I did repair install:

    1.I reinstalled the Bootcamp 3.0 from my original mac CD, not Leopard snow generic cd, which I used before.

    2.Applied update 3.1. I could not used the one on Apple support page (weird). I used the one on Web site:

    3. Reinstall network drive

    On the original CD go to Boot Camp/Driver/Broadcom/

    Install BroadcomNetworkAdapterWin7_64

    You should now have under Device manager/Network adapters/ Broadcom 802.11n Network adapter

    I got full Wifi network!


    Hope it works for you!

    No issues reported here. I am running Windows 7 Ultimate via Parallels Desktop, and I have not had any issues whatsoever.
