Will my microwave oven or 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/g 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.

To reduce interference, you can move a 2.4 GHz cordless phone away from your Wi-Fi equipped computer or base station. Interference usually only happens with older microwave ovens. 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 manufacturer for specific instructions for your equipment.
