Desktop is connected to a wireless network, but can't access internet?
Hello!

So I have a Windows HP Pavilion w1907 desktop. My computer says that I am connected to a wireless network. However, I cannot use any programs, like AIM or Mozilla Firefox, iTunes, or any other programs that require internet connection to work. I visited the Network and Sharing Center, which says I'm connected to an unidentified network but not the Internet. How can I fix this asap? Any help will be greatly appreciated! I am so frustrated, to be honest. Thank you in advance!

What security applications (firewall, security suite, anti-virus, etc.)?

Please attach a screen shot of the Networks page of the Xirrus Wi-Fi Inspector and show ...

Start, Run, CMD, OK to open a command prompt:
(For Vista or 7 type CMD in the Search box after Start)

Type the following command:

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If necessary use a text file and removable media to copy the results to a computer with internet access.

Norton could easily be blocking. Uninstall it and run Symantec's Removal Tool. You may reinstall it after getting your network going.

Also run these repairs ...

(From a JohnWill post)

TCP/IP stack repair options for use with Vista or 7.

Start - All Programs - Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

Reboot the machine.

The commands aren't working. For the first one, it says I have to restart my computer to complete it, but it doesn't finish. As for the last ones, it says that a user isn't specified. -.-
