6 and 11, you should choose channel 1.
If there are many neighboring networks, you may find that most use
channels 1, 6 and 11. In that case, you may find you achieve better
performance by choosing an unused channel between the most-used
channels, for example one of channels 3, 4, 8 or 9. You may need to
experiment to find the best channel. Note good candidate channels to use
for your network. Then, navigate to the Wireless Basic page.
Hover over the Wireless menu item to bring the Wireless submenu options
into view, then click the Basic submenu option. This brings you to the
Wireless Basic page:
Select the desired channel from the Channel pulldown, and click Save. Wait
for a minute or so for client devices to resynchronize to the new channel.
Check to see whether wireless performance has improved. If not, you can try
another channel selection.
