Vigor router can scan all regulatory channels and find working APs in the neighborhood.
Based on the scanning result, users will know which channel is clean for usage. Also, it can
be used to facilitate finding an AP for a WDS link. Notice that during the scanning process
(about 5 seconds), no client is allowed to connect to Vigor.
