Current WLAN network security codes are unavailable
If you are prompted for a network key or a name (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 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 > Network and Sharing Center.
2.Click Manage wireless networks in the left panel.
A list showing the available WLANs is displayed. If you are in a hotspot where several WLANs
are active, several are 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.
Troubleshooting wireless connection problems 21 
						

							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 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.Click Manage wireless networks in the left panel.
A list showing the available WLANs is displayed. If you are in a hotspot where several WLANs
are active, several are 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.
If the computer still cannot make a connection to a WLAN, restart the wireless router. For details,
refer to the router manufacturers instructions.
Connecting to a local area network (LAN)
Connecting to a local area network (LAN) requires an 8-pin, RJ-45 network cable (purchased
separately). If the network cable contains noise suppression circuitry (1), which prevents interference
from TV and radio reception, orient the circuitry end of the cable (2) toward the device.
To connect the network cable:
WARNING!To reduce the risk of electric shock, fire, or damage to the equipment, do not plug a
modem cable or telephone cable into an RJ-45 (network) jack.
1.Plug the network cable into the network jack (1) on the computer.
