Suddenly Wireless Network says No Internet Access

Hey guys,

I've read numerous threads and have been trying for the past six hours trying to get my stupid computer to connect to the wireless network. I have a Dell Studio XPS 1340 laptop, wireless card is "Dell Wireless 1510 Wireless-N WlAN Mini-card", router is cicsco E4200. I don't know that much about computers, so i've been relying on what people have suggested doing in former threads.

I know there is nothing wrong with the router, because the other computers in the house both by LAN and wireless can connect to the internet and it runs super fast. Mine was working great until suddenly last night, it said it was connected but that there was no internet access. I did upgrade my computer from Vista to Windows 7, but that was about a month ago, and I've had no problems since. When I clicked on the diagnostic button to try and let it resolve it itself, it pops up saying "DNS server isn't responding"

This is what I have done already:
1) reboot router, modem (shouldn't be a problem with them since all other computers can access perfectly)

2) I tried turning on/off my wireless on the laptop, and restarting, etc.

3) when I tried to ipconfig /release, it says "no operation can be performed on Local area connection while it has its media disconnected - same goes for when I do ipconfig /renew

4) I also tried flushing the DNS, by typing ipconfig /flushdns, it says successfully flushed the DNS resolver Cache, but after rebooting, nothing's changed.

5) I also went to properties for the wireless network, under Internet Protocol Version 4, I set it to use a manual IP address
IP 192.168.0.22
Subnet mask 255.255.255.0
Default gateway : 192.168.0.1
Preferred DNS : 208.67.222.222
Alternate DNS server 208.67.220.220

I don't understand how the wireless all of a sudden stopped working. Is this some retarded Windows 7 thing. This never happened to me before - before, especially if I've been doing a lot of downloading, I have to unplug the modem, and everything is great. But, now it's just my computer that's not working. So strange...any clues, guys? This is getting frustrating, I'm about to throw it in the trash and just get a new computer, hahaha. Thanks for your help!

PS. I forgot to mention, when I plug in the ethernet, it connects, but still says no internet access.

i have this exact same problem did u get it fixed?

I did. But, I had to reinstall windows7. I think I messed it all up when I was upgrading from Vista to 7. There probably is a better way, but sometimes it's great to just get a fresh start. Fortunatley I had backed everything up when upgrading. I had only been using windows 7 for a little bit before I ran into this prob. I don't remember if it was because of the upgrade or it might've been a virus.

When upgrading from Vista the network stack and also winsock tends to get corrupted. Saving the file below, unzip and running the file until your machine reboots should fix this problem.

I can't find the original batch file I used to convert to the .exe. but yes I'm the one who created this very useful .exe and it's now been distributed to all parts of the world.
