Wireless Communication Function Notes - Canon EOS 77D Wi-Fi (Wireless Communication) Function Instruction Manual

Wireless Communication Function Notes

If the transmission rate drops, the connection is lost, or other problems
occur when using the wireless communication functions, try the
following corrective actions.
Distance Between the Camera and the Smartphone
If the camera is too far from the smartphone, a Wi-Fi connection may
not be established even when Bluetooth connection is possible. In such
a case, bring the camera and the smartphone closer together, then
establish a Wi-Fi connection.
Installation Location of Access Point Antenna
When using indoors, install the device in the room where you are

using the camera.
Install the device where people or objects do not come between

the device and the camera.
Nearby Electronic Devices
If the Wi-Fi transmission rate drops because of the influence of the
following electronic devices, stop using them or move further away from
the devices to transmit communication.
The camera communicates over Wi-Fi via IEEE 802.11b/g/n using

radio waves in the 2.4 GHz band. For this reason, the Wi-Fi
transmission rate may drop if there are Bluetooth devices,
microwave ovens, cordless telephones, microphones,
smartphones, other cameras, or similar devices operating on the
same frequency band nearby.
Notes for Using Multiple Cameras
When connecting multiple cameras to one access point via Wi-Fi,

make sure the cameras' IP addresses are different.
When multiple cameras are connected to one access point via

Wi-Fi, the transmission rate drops.
When there are multiple IEEE 802.11b/g/n (2.4 GHz band) access

points, leave a gap of four channels between each Wi-Fi channel
to reduce radio wave interference. For example, use channels 1, 6,
and 11, channels 2 and 7, or channels 3 and 8.
