The Network connections window is displayed, and Windows resets your network device and
attempts to reconnect to one of the preferred networks.
Current network security codes are unavailable
If you are prompted for a network key or an SSID when connecting to a WLAN, the network is protected
by security. You must have the current codes to make a connection on a secure network. The SSID and
network key 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 these steps to connect to the network:
1. Select Start > Control Panel > Network and Internet Connections > Network Connections.
A list showing the available WLANs is displayed. If you are in a hotspot where several WLANs are
active, several will be displayed.
2. Right-click the network, and then click Properties.
3. Click the Wireless Networks tab.
4. Select 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.
5. Click the Association tab, and then enter the correct wireless encryption data into the Network
key field.
6. 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 other wireless devices such as a microwave, cordless phone, or cellular
phone to be sure that they 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 Connections > Network Connections.
2. Right-click the network, and then click Properties.
3. Click the Wireless Networks tab.
A list showing the available WLANs is displayed. If you are in a hotspot where several WLANs are
active, several will be displayed.
4. Select a network, and then click Remove.
