Validating idetity on belkin network
Default wireless security settings are not published for obvious security reasons: sign in to the router to determine your current settings.wireless switch on a laptop may be turned off, or the adapter may be disabled in Device Manager).
If you can see your network but the system does not ask you for your Key or Passphrase (Windows) or Password (Mac OSX) then it is trying to use a previously stored profile for the same network name (SSID).
Firstly you can not use WPA, you can use WPA-PSK/WPA2-PSK or WEP.
I had an unsecure network connection so I changed the security settings of my tp-link router from WEP to WAP-TKIP.
The MAC address of that PC is used by Comcast to get your connection.So what I did was just: 1) open network connections 2) click properties 3) in the GENERAL tab, click INTERNET PROTOCOL (TCP/IP) 4) click Properties 5) choose obtain DNS server automatically My internet worked afterwards.This wasn't my solution unfortunately as I was already using the option for obtaining DNS server automatically.Now you can break WPA/WPA2 as well if you capture the handshake packets.Information about default settings is publicly available by web search.
