This is my first post so thanks for having me!
I recently installed Windows 7 Professional 64bit on my computer. It was running Vista Home Premium. I usually stay away from upgrade discs and always try to purchase the full verison but I purchased the Windows 7 Upgrade for $30 through a student discount. I couldnt pass up that price.
Anyway, everthing has been great except for one little quirk. When I start up my computer and the desktop loads I do not get an internet connection. If I open IE it tries to open my home page for a long time, then finally gives the Diagnose Conneciton Problems button. If I click on the network icon by the clock in the system tray it will give me one network which is the house icon but it will say "no internet" in blue. Below that is another network with the park bench icon which also says "no internet".
Now, with it in this state I can still click on Start then Network and browse files on my other pc connected to the same router. So, my home network and file sharing is set up and working correctly. The problem is only with my internet connection.
Here is what I have noticed, though. I can go to the device manager, disable my network card, re-enable it, wait a couple of seconds, and then my internet connection is flawless. When I click on the network icon in the system tray it just shows connected to Network with internet access and the home icon. No park bench or second network listed at all. But, the next time I reboot or if I shut down and start up again I have to disable and re-enable the NIC before the internet works.
I did not have this problem in Vista.
Here is what I have done to troubleshoot...
First things first... I updated the drivers for the network card, which by the way, is an integrated Marvell Yukon 88E056 on an Asus P6T Delux motherboard. This particular motherboard has two of those on it which leads me to my next troubleshooting step.
I went to the bios and disabled the extra ethernet port on the board so now device manager only shows one. Same issue. I tried alternating ethernet ports.. disabling the other and re-enabling the first one I disabled in bios. Both ports do the same thing.
I tried updating all of the drivers available from Asus for Windows 7 for this board including chipset and BIOS. I then tried removing the ethernet card totally using command prompt and installing it's drivers manually through command prompt. The driver removal and install worked but the issue presists.
Heres the weird part... As a last resort I tried eleminating the router as a possible cause. I plugged my DSL modem straight into the ethernet port. I rebooted 10 times to test it. The problem goes away when I take the router out of the equasion. The router I am using is a Netgear WGR614 v6. Nothing changed on the router between upgrading from Vista to Windows 7. My other Vista pc and my XP laptop on wifi neither have any issues with internet connections. So, I tried switching ports on the router, power cycling the router and I tried resetting the router to factory settings and reconfiguring it.
I am out of ideas...
