A wireless LAN connection has low signal strength, drops or acts erratically.

Interference from a 2.4 GHz or 5 GHz telephone may cause connection issues when using a 802.11a, 802.11b, 802.11g, or 802.11n wireless network (WLAN). These wireless standards use the same frequencies. Other wireless devices such as Bluetooth devices, baby monitors, garage door openers, microwave ovens or wireless toys may cause interference. Also, large power transmission lines or metal surfaces such as walls or desks may interfere. The connection issues may include pauses, disruptions or other erratic behavior with the wireless network.

The following are some suggestions that may resolve the issue:

• Change the location of the wireless router or the base station of the cordless phone.
• Change the channel used by the wireless router.  
• Operate the phone with the antenna lowered if that option is available.
• Use a cordless phone that operates on a frequency other than 2.4 GHz.
• Limited the use of Bluetooth devices or turn off the Bluetooth adapter in the computer.

• This issue also can occur if you are connected to an unsecured wireless network, or a Guest network. If you are using a wireless connection, make sure you are connected to a secured Wi-Fi® network (indicated by a lock icon) in the Wi-Fi settings list.

IMPORTANT:

• For information on changing the channel of a wireless router or access point consult the manual included with the device or contact the manufacturer directly.
• Many 2.4 GHz and 5 GHz cordless telephones operate with what is called frequency hopping technology. This technology utilizes the entire frequency range also used by 802.11a, 802.11b, 802.11g and 802.11n wireless devices. Thus changing the channel of the wireless router may not eliminate the interference problem.
