Wireless connection problem
The wireless network connection is sometimes disabled.
The wireless network connection status is affected by the environment where the Brother printer and other
wireless devices are located. The following conditions may cause connection problems:
■
A concrete or metal framed wall is installed between the Brother machine and the access point.
■
Electric appliances such as televisions, computer appliances, microwave ovens, intercoms,
mobile/cellular phones and the battery chargers and AC power adapters are installed close to your
network.
■
A broadcast station or high-tension wire is located close to your network.
■
A fluorescent light is being switching ON or OFF.
