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: http://www.sevenforums.com/attachme...25-network-instability-unstableconnection.png Closing the page is done by myself, but the video was left there until it reaches the end. My local IP address is 192.168.1.6 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: Verizon 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.
