Choose The "Quietest" Channel For Your Wireless Network - Casa Systems CFW-4221 User Manual

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.
