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 > Network > Network and Sharing Center > 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.
