This setting lets you set a gating factor for channel re-assignment so that the
network is not continually disrupted for minimal gains in efficiency.
network is not continually disrupted for minimal gains in efficiency.
For example, if channel interference must be reduced by 75%, and the proposed
channel assignments will only reduce interference by 30%, then channels will not be
re-assigned. However; if you re-set the minimal channel interference benefit to 25%
and click Update, the proposed channel plan will be implemented and channels re-
assigned as needed.

IEEE 802.11b/802.11g modes (802.11 b/g) support use of channels 1 through 11.
For the “b/g” radio band, the classic set of non-interfering channels is 1, 6, 11.
Channels 1, 4, 8, 11 produce minimal overlap.
For the “b/g” radio band, the classic set of non-interfering channels is 1, 6, 11.

This setting (along with the interference reduction setting) is designed to help weigh
the cost/benefit impact on network performance of re-assigning channels against the
inherent disruption it can cause to clients during a busy time.
