WLAN connection is very weak
If the connection is very weak, or if the computer cannot make a connection to a WLAN, minimize
interference from other devices by:
● Moving the computer closer to the wireless router or access point.
● Temporarily disconnecting devices such as a microwave, cordless phone, or cellular phone.
To force 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 appears. If you are in a hotspot where several WLANs are
active, multiple networks appear.
3. Select 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 cannot make a connection to a WLAN, restart the wireless router. For details, see the
router manufacturer's instructions.
