on a secure network. The SSID and security code are alphanumeric codes that you enter into your computer to identify your computer to the network.

For a network connected to your personal wireless router, review the router user guide for instructions on setting up the same codes on both the router and the WLAN device.

For a private network, such as a network in an office or at a public Internet chat room, contact the network administrator to obtain the codes, and then enter the codes when prompted to do so.

Some networks change the SSID or network keys used in their routers or access points on a regular basis to improve security. You must change the corresponding code in your computer accordingly.

If you are provided with new wireless network keys and SSID for a network, and if you have previously connected to that network, follow the steps below to connect to the network:

1.Select Start > Control Panel > Network and Internet > Network and Sharing Center.

2.In the left panel, click Manage wireless networks.

A list showing the available WLANs is displayed. If you are in a hotspot where several WLANs are active, several will be displayed.

3.Select the network in the list, right-click the network, and then click Properties.

NOTE: If the network you want is not listed, check with the network administrator to be sure that the router or access point is operating.

4.Click the Security tab and enter the correct wireless encryption data into the Network security key box.

5.Click OK to save these settings.

WLAN connection is very weak

If the connection is very weak, or if your computer cannot make a connection to a WLAN, minimize interference from other devices, as follows:

Move your computer closer to the wireless router or access point.

Temporarily disconnect wireless devices such as a microwave, cordless phone, or cellular phone to be sure that other wireless devices are not interfering.

If the connection does not improve, try forcing the device to reestablish all connection values:

1.Select Start > Control Panel > Network and Internet > Network and Sharing Center.

2.In the left panel, click Manage wireless networks.

A list showing the available WLANs is displayed. If you are in a hotspot where several WLANs are active, several will be displayed.

3.Click a network, and then click Remove.

Cannot connect to the wireless router

If you are trying to connect to the wireless router and are unsuccessful, reset the wireless router by removing power from the router for 10 to 15 seconds.
