Cordless Phones and Wireless Networks

Will my cordless phone interfere with my Wi-Fi network? Microwave ovens and many cordless phones operate in the 2.4 GHz spectrum, the same radio spectrum used by 802.11b Wi-Fi wireless networks. That means they can cause interference — but in most instances this will just slow down the Wi-Fi connection; it won't stop transmission or break the connection.  You may also get occasional static or a dropped call on your cordless phone.

To reduce interference, you can move a 2.4 GHz cordless phone away from your Wi-Fi equipped computer or base station.  You can also try changing the channel on which your Wi-Fi network operates.  In addition, some manufacturers have developed and implemented special technologies that can minimize interference from cordless phones and ovens. Check with the wireless equipment manufacturer for specific instructions for your equipment.
