Safety and product care
Your gateway is an electronic device that sends and receives radio signals. Please take the time to read this
list of precautions that should be taken when installing and using the router.
Do not disassemble the gateway. There are no user-serviceable parts.
Do not allow the gateway to come into contact with liquid or moisture at any time. To clean the device,
wipe it with a damp cloth.
Do not restrict airflow around the device. This can lead to the device overheating.
Do not place the device in direct sunlight or in hot areas.

Transport and handling
When transporting the gateway, we recommend returning the product in its original packaging. This helps to
reduce the risk of damage to the product.
Attention
– In the event the product needs to be returned, ensure it is securely packaged with appropriate padding to prevent
damage during courier transport.
Placement of your gateway
The wireless connection between your gateway and your wireless devices will be strong when they are in
close proximity and have direct line of sight. As your client device moves further away from the gateway or
solid objects block direct line of sight to the router, your wireless connection and performance may degrade.
This may or may not be directly noticeable and is greatly affected by the individual installation environment.
If you have concerns about your network’s performance that might be related to range or obstruction
factors, try moving the computer to a position between three to five metres from the gateway to see if
distance is the problem.
Note
– While some of the items listed below can affect network performance, they will not prohibit your wireless network from
functioning; if you are concerned that your network is not operating at its maximum effectiveness, this check list may help
Try not to place the gateway near a cordless telephone that operates at the same radio frequency as the
gateway (2.4GHz/5GHz).
Avoiding obstacles and interference
Avoid placing your gateway near devices that may emit radio “noise,” such as microwave ovens. Dense
objects that can inhibit wireless communication include:
Refrigerators
Washers and/or dryers
Metal cabinets
Metallic-based, UV-tinted windows
If your wireless signal seems weak in some spots, make sure that objects such as those listed above are not
blocking the signal’s path (between your devices and the gateway).
Cordless phones
If the performance of your wireless network is impaired after considering the above issues, and you have a
cordless phone:

12 of 64
CFW-4221/4222 – User Guide
UG01433 v1.03 November 2022

Try moving cordless phones away from your gateway and your wireless-enabled computers.
Unplug and remove the battery from any cordless phone that operates on the 2.4GHz or 5GHz band (check
manufacturer’s information). If this fixes the problem, your phone may be interfering with the gateway.
If your phone supports channel selection, change the channel on the phone to the farthest channel from
your wireless network. For example, change the phone to channel 1 and move your gateway to channel 11.
See your phone’s user manual for detailed instructions.
If necessary, consider switching to a 900MHz or 1800MHz cordless phone.
Choose the “quietest” channel for your wireless
network
In locations where homes or offices are close together, such as apartment buildings or office complexes,
there may be wireless networks nearby that can conflict with your wireless network. Your wireless adapter
may include a utility to assist in scanning for the least congested network, otherwise you may be able to find
another piece of software that can be used. These tools display a graphical representation of the wireless
networks in range and the channels on which they are operating.
Try to find a channel which is not as busy and does not overlap with another one. Channels 1, 6 and 11 are
the only channels on 2.4GHz which do not overlap with one another, and you should ideally choose one of
these channels.
Experiment with more than one of the available channels to find the clearest connection and avoid
interference from neighbouring cordless phones or other wireless devices.
