restrict stations from using specific category class if it is
checked.

answer the response request while transmitting WMM packets
through wireless connection. It can assure that the peer must
receive the WMM packets.

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.
This page is used to scan the existence of the APs on the wireless LAN. Yet, only the AP
which is in the same channel of this router can be found. Please click Scan to discover all the
connected APs.
