follow the rule of choosing a channel separated by 5 from all other channels. For
example, if there are two neighboring networks using channels 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.
For the 5 GHz band:
Look at the Channel column. This shows the channels that your neighboring
networks use. Available channels include 36 – 48 and 149 – 165. Some channels
from 52 – 144 may also be available; however, these channels may be allocated to
uses including weather RADAR and other government sanctioned applications.
As of this writing (spring of 2016) it is unusual for the 5 GHz band to be crowded.
If it is crowded in your location, choose a channel or channels that are unused or
little used by neighbors. 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:
