Windows 7 Ultimate (Full Release) cannot connect to Home Network (for internet access) Unidentified Network (no internet) only
I am so frusterated, but I understand there are bugs. But... earlier this morning, I was able to access the internet fine after upgrading my Windows Vista 32 to Windows 7 Ultimate (the actual release version, but got for the house party). Now, for some reason, it cannot connect the the internet. It will not connect to the home network that it used to connect to. It will now only conect to Unidentified Network with no internet access. I cannot even get the IP/mac, anything on the router's DHCP table. When I try the ipconfig /renew... it hangs for a bit, then says there is an error b/c the dhcp cannot be accessed. I've done everything I know how to. I'm trying one last thing, but I cannot get it to work. I have even restored the computer to the time I did my last update, when I KNOW I was able to get the internet, still nothing. Please help!!! Please! Anything would be greatly appreciated. I would love to show this off to everyone at the Windows 7 house party, but not if I can't get the 'net. Thanks.

I was able to fix my problem. For some odd reason, the driver from Vista was used during the Windows 7 Ult setup and persisted to work correctly for awhile. I then did some updates and oddly enough, the driver became either corrupted, or non-functional. I therefore, uninstalled the NIC driver (with the option to delete the files on disk as well). then restarted the computer, allowed Windows 7 to find a Microsoft (MS) Windows 7 (Win7) driver, and poof, everything worked like a charm. And to think after all of that hard work. I even uninstalled and let it reinstall, but using the old, corrupted/non-functional version, which did not fix it. But now, it's all good and working after that fix was completed. Hope this may help anyone else in my shoes down the line as well. Good luck. And be sure to at least have a backup of the original driver somewhere (other than the net, which isn't able to be accessed) before you try deleting the actual files on the disk too. That would suck if it didn't work and you didn't have any way to at least revert back, LoL. anyway, thanks anyway though. All good now :)

Thanks for sharing your experience with us to avoid the similar issues. I also would like to share a new feature in Windows 7, the Network troubleshooter. Generally, we can troubleshoot the home network issue by using the Network troubleshooter in Windows 7. In TruHuSKa2009’s case, the Network troubleshooter will detect the network card driver issue and provide the suggestion to install the correct network card driver.Arthur Li - MSFT

I had a similar issue, turns out it was the "Updated" Drivers for my onboard Ethernet Controller. I actually had to roll back the drivers to allow my connection to work. This is a problem I was hoping would be fixed before the final release, but apparently was not as I had the same issue in the final release.

This is a problem I was hoping would be fixed before the final release, but apparently was not as I had the same issue in the final release. You had better install the latest version from the hardware manufacturer’s website. Microsoft Update also offers driver updates, but it may be delayed for a few time after releasing by the third party hardware manufacturers. If the official driver cannot work normally, I hope you can report it to the hardware manufacturer and ask them improve it. Note: this is third party manufacturers’ work.Arthur Li - MSFT

That is the one I am using now. I got the ones direct from the manufacturer. The drivers from the manufacturer work, just not the ones that Microsoft Update offered as an "Update". It is all ok though, I was able to quickly diagnose the trouble with the issue, and correct it. I am no novice when it comes to working on computer issues. It helps that I am the assembler of my own computer...so i know exactly what i have in my computer and where to get the best drivers for all of my stuff.

It is very simple. If this happens again, just go to "Internet options" of your browser Tools menu and get rid of all history files, cookies and Temp. Internet files and reboot your computer. that is all takes in most cases to get back your internet connection.Good Luck !

Unless of course you are pulling an Invalid IP Address due to driver issues...in which case deleting your Cookies and Cache will have no effect.

In fact, the driver updates Microsoft Update offer also provided by the third party manufacturers. I do receive some feedbacks about the Realtek Network Driver Update (NDIS6.0) causes some issues. Troubled31707, did you install the same NDIS6.0 update that caused the issue? I would like to collect more information about it. Thanks for your cooperation. Arthur Li - MSFT

Yep, That's the one. What information are you wanting to know?

Yep, That's the one. What information are you wanting to know? Hi Troubled31707, That’s great! Would you please download and install the NDIS 6.0 driver update again and collect the following information for us? After that, roll back your network card driver. Setupapi.dev.log ============ 1. Rename the following files: (I'm assuming your Windows 7 is installed in C:\Windows) C:\Windows\inf\setupapi.dev.log 2. Restart the computer. 3: Reinstall NDIS 6.0 via Microsoft Update. A new setupapi.dev.log file will be created and the complete installation process including error information will be recorded in it. Please send this file to file to us. WindowsUpdate.log ============ 1. Press the Windows key and the R key at the same time, type: %windir% and press Enter. 2. Locate a file named "WindowsUpdate.log" and send it to us. Please upload them to SkyDrive and provide us the link. Thanks for your time. Arthur Li - MSFT

I had this problem today. I attempted to install Windows 7 x64 with an Asus P5NSLI motherboard and experienced the symptoms described in this thread. I NEVER had a connection to the Internet. Others related that the adapter functioned for a time, and then began misbehaving. After several hours of troubleshooting (I tried all of the suggestions here, with respect to changing the values in the Advanced tab of the device's properties) as well as using the newest Windows 7 64-bit driver from Marvell (11.28.6.3) from http://extranet.marvell.com/drivers/driverDisplay.do?driverId=207 , I gave-up. I ended-up having to install Windows 7 x86, on which the driver included with Windows functions as expected (perfectly fine). It seems as though this problem is with the firmware or chipset, and not with Windows or the driver. Blame Marvell.
