When using a Wi-Fi network, try the following corrective actions if the transmission rate drops, 
the connection is lost, or other problems occur.

 

When using a Wi-Fi network indoors, place the access point in the same room where you 
are using the camera.

 

Place the access point in an open, unobstructed location, where people or objects do not 
come between it and the camera.

 

Place the access point as close as possible to the camera. In particular, note that during 
outdoor use in poor weather, rain may absorb radio waves and disrupt the connection.

 

If the transmission rate over a Wi-Fi network drops because of interference from the 
following electronic devices, switching to the 5 GHz band or to a different channel may 
solve the problem.

 

Wi-Fi networks using the IEEE 802.11b/g/n protocol operate in the 2.4 GHz band. For this 
reason, the transmission rate may drop if there are nearby microwave ovens, cordless 
telephones, microphones, or similar devices operating on the same frequency band.

 

If another access point operating on the same frequency band as the transmitter is used 
nearby, the transmission rate may drop.

 

Check that there are no IP address conflicts among the devices connected to the same 
network.

 

If multiple transmitters are connected to a single access point, connection speeds may be 
reduced.

 

To reduce radio wave interference when there are multiple access points using IEEE 
802.11b/g or IEEE 802.11n (in the 2.4 GHz band), leave a gap of four channels between 
each wireless access point. For example, use channels 1, 6, and 11, channels 2, 7, and 
12, or channels 3, 8, and 13. If you can use IEEE 802.11a/n (in the 5 GHz band), switch to 
IEEE 802.11a/n and specify a different channel.
