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 > 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 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.
If the computer still cannot make a connection to a WLAN, restart the wireless router. For details, refer
to the router manufacturer's instructions.
Using the modem (select models only)
The modem must be connected to an analog telephone line using a 6-pin, RJ-11 modem cable (select
models only). In some countries or regions, a country- or region-specific modem cable adapter (select
models only) is also required. Jacks for digital PBX systems may resemble analog telephone jacks, but
they are not compatible with the modem.
WARNING! Connecting the internal analog modem to a digital line can permanently damage the
modem. Immediately disconnect the modem cable if you accidentally connect it to a digital line.
If the modem cable contains noise suppression circuitry (1), which prevents interference from TV and
radio reception, orient the circuitry end (2) of the cable toward the computer.
Connecting a modem cable (select models only)
WARNING! To reduce the risk of electric shock, fire, or damage to the equipment, do not plug a modem
cable (select models only) or telephone cable into the RJ-45 (network) jack.
