Operating mode
Select the operating mode. Available options are: 
Access point and WDS bridge: Standard operating mode provides support for all 
wireless functions.
Access point only: Only provides AP functionality, WDS links cannot be created.
WDS bridge: Only provides WDS functionality. Wireless client stations cannot connect.
Monitor: Puts the radio in promiscuous mode (no transmissions). Both AP and WDS 
bridge functionality are disabled. Use this...

NoteIn 802.11n (2.4 GHz) and 802.11n (5 GHz) modes, the V-M200 does not permit non-
802.11n clients to associate. Also in this mode, the V-M200 does not use protection 
mechanisms (RTS/CTS or CTS-to-self) to enable legacy APs to operate on the same 
frequency. This can potentially cause problems with legacy (802.11a/b/g) APs operating on 
the same channel, but provides the best throughput for the V-M200 and its 802.11n clients. 
In 802.11n/a, 802.11n/g, and...

When Wireless mode is 802.11n (5 GHz) or 802.11n/a and Channel width is Auto 20/40 
MHz, the channel numbers in the Channel list include either a “(1)” or “(-1)” to their right. 
A “(1)” indicates that the 40 MHz channel is formed from the indicated channel plus the next 
channel. A “-1” indicates that the 40 MHz channel is formed from the indicated channel plus 
the previous channel.
With a 40 MHz Channel width in the 5 GHz band, channel selection and...

Automatic channel: When the radio has its Channel set to Automatic, scanning is 
performed for all the channels in the currently selected Wireless mode when the V-M200 
starts up.
Background scanning: For any other radio configuration, scanning is controlled by the 
settings on the Rogue AP detection page. To enable scanning, select the Repeat scan 
checkbox and set the Scan interval. Scanning is performed for all the channels in the 
currently selected...

Scanning for rogue APs
When the V-M200 discovers an AP during a scan it compares the MAC address of the AP 
against the list of authorized APs (which you must define). If the scanned AP does not appear 
in the list of authorized APs, it is displayed in the Rogue access points table.
If the V-M200 is in background scanning mode, it will scan all channels in the currently 
selected radio operating mode approximately once every two hours (assuming the default...

To add access points that do not appear in the All access points table:
1.Select the option Manually configure. 
2.Specify the MAC address of the access point that you want to authorize. The 
MAC address must be in the following format: 12 hexadecimal numbers 
separated by colons, with the values “a” to “f” in lowercase. For example: 
00:03:520:a0:f01.
3.Select Add. The MAC address is added to the Authorized access points table.
3.Select Save to...

No: Client station can only transmit/receive 802.1X packets. 
Filtered: Client traffic is blocked by the MAC filtering feature.
Authentication
Indicates how the client station was authenticated.
Association time
Indicates how long the client station has been associated with the V-M200.
Signal
Indicates the strength of the radio signal received from the client station. Signal strength is 
expressed in decibel milliwatt (dBm). The higher the number...
