A message in the Wireless little Window that says Connected does not means that you really have a valid functional connection.

If everything above is OK you have to be able to connect to the Wireless Router. (WIFI Hot Spot).

Connecting to the Router means that you can enter the Router's core IP into an address bar of a browse, be able to connect, see, and configure the Router's menus (the Wireless Router's extended manual should explain how-to).

If it does not connecting to your own Wireless Router, log from any computer that can connect to Wireless Router with a Wire, disable the Wireless Security, make sure that the Wireless broadcast SSID is On,  and try to connect with No Wireless security.

Enable the Wireless security after you mange to establish a functional connection.


Many Wireless cards' drivers also install the vendor's Wireless utility.

Make sure that if there is a vendor's Wireless Utility thes Not Running together with the Windows native Wireless utility (WLAN Service) .


Software Firewall might block the Local traffic to the Network that you are trying to use because it is Not adjusted to the Network Trust Zone.

Make sure that No Firewall is preventing/blocking the Wireless components to get to the Network.

Some 3rd party Software Firewalls keep blocking aspects of Local Traffic even it they are turned Off (disabled).If possible configure the Firewall correctly, otherwise totally uninstall it, and get rid of its residual processes to allow clean flow of local network traffic.

If the 3rd party software is uninstalled or disables, make sure that Windows native Firewall is On .

3rd party Network mangers like Bonjour, and NetMagic can block local traffic too.


Working TCP/IP stack (Network IP number) should look this way.

Right click on the Wire card Network Connection, choose Status, Details, and see if it got an IP and the rest of the settings.


Description is the card manufacturing data.

Physical address is the card's MAC number.

The xx should be a number from 0 to 255 (all xx same number).

yy should be from 0 to 255

zz should be from 0 to 255 (all zz the same number.

The lease date should be valid to the current time.

*Note 1. IP that starts with 169.xxx.xxx.xxx is not valid functional IP.

*Note 2. There might be an IPv6 entries too. However, they are not functional for Internet traffic or LAN. They are needed for Win 7 special HomeGroup configur
