A poor network environment can cause delays in video streaming during meetings.
When using a wireless network, communication quality may deteriorate or communication may be lost, depending on the environment in which the machine is used. If these problems occur, use a wired network instead. To switch to a wired network, you must first turn the machine off and then turn it back on.
When using a wireless network, radio or electromagnetic interference or weak reception may cause the following problems to occur during meetings:
Delays in video streaming.
Video is stopped.
Audio of other party cuts out.
Synchronization between video and audio is lost.
Audio quality deteriorates.
Meetings are automatically ended or left.
Delays in video streaming occur when sharing computer screen.
Your video and the other party’s video disappear and only audio is heard.
Screen image does not display properly when the screen layout is changed.
The Contact List or contact status do not appear, or it takes longer than expected for each to be displayed.
The attempt to update the firmware fails, or it takes an excessively long time for the update to finish.
The machine does not start.
You cannot connect to other party.
Solutions
If you experience one of the problems above, take one of the following actions. The action to be taken depends on the wireless network environment you are using:
If IEEE802.11n, IEEE802.11g, and IEEE802.11b are available in a wireless network environment, IEEE802.11b is sometimes preferred for network connection. The recommended line speed for the machine is 1 Mbps. To use the machine at a stable line speed, we recommend using it in a wireless network environment in which only IEEE802.11n/g is available.
Avoid environments that have multiple wireless LAN standards.
Turn off any wireless networking or radio devices that are not being used.
If there are multiple devices in the environment that support IEEE802.11n, use IEEE802.11n with a single channel.
Use the machine in an environment with stable reception, making sure to confirm the distance from the access point and check for any obstructions.
If the environment has multiple wireless LAN standards, change the access point channel. There should be a difference of at least five between the channel settings for each LAN standard. For example, set one standard to channel 1 and the other to channel 6.
Keep the machine as far away as possible from highly conductive objects such as metal.
This wireless product uses the 2.4 GHz band. Make sure there is no industrial, scientific, or medical equipment that uses the same frequency band currently in operation, such as a microwave. Interference can cause communication to become unstable. Before using the machine, make sure that there is no equipment around that may potentially cause interference.
If you experience radio interference or other wireless networking problems, please call the support desk.
