    dual boot installed win 8 --> win7 internet crashed?


    Hey all, I just installed win 8 dualboot a couple hours ago, to complement my win 7 (installed the developer preview of course). Immediately after, my internet (ethernet or wifi) would not work on my win 7. Ethernet would result into 'unidentified network' and the machine won't pick up the ip address or something, I think. No matter how hard the IT guys tried, they couldn't get it to work. Wi-fi could be because I have a lousy router, but I am not sure. Is there a way to fix ethernet/both? I have a feeling ethernet is 100% related to win8 installation, wi-fi not so sure. I checked the drivers -- they are the same as before. I uninstalled, reinstalled, disabled/enabled, etc. etc. etc., nothing happened. Win 8 internet works fine. Thank you!

    Problem solved -- apparently installing win 8 (even dual-boot) induces something in the system that makes your Ethernet card (provided it's Marvell Yukon I think) unusable unless you update the drivers on the Win 7 side. Did that, it works golden now. Wi-fi was just lousy because of the router.
