Multiple stations or Stations WDS can connect to an
AP WDS (unless the PTP Country code is used and the
PTP-MAC of the peer radio is entered) In Figure 52,
the Add button creates a virtual access point (VAP) on
the second . You should choose AP WDS mode for the
VAP's wireless network e.g. “M8” so that devices in
Station WDS mode can connect to this network. The
pair of Station WDS and AP WDS on the same board
extends the wireless coverage. If the board has two
radios, one onboard and one card radio, one radio can
be the Station WDS and the other radio can be the AP
WDS. Therefore the Station WDS with AP WDS on the
same board functions as a repeater.
In the non-WDS mode, the Station translates all the
packets that pass through it to its own MAC address,
thus resulting in a lack of transparency. A
consequence is that the ARP table of the access point
would show the MAC address of the Station assigned
to IP addresses of both the Station and the computer
connected to it.
Wireless Security
Encryption: Chooses between No Encryption (open)
and the following encryptions: WEP Open System,
WEP Shared Key, WPA-PSK, WPA2-PSK, WPA-
PSK/WPA2-PSK Mixed Mode, WPA-EAP, and WPA2-
EAP.
WEP
Wired Equivalent Privacy (WEP) is the oldest and least
secure encryption algorithm. Stronger encryption
using WPA or WPA2 should be used where possible.
For the WEP Open System and WEP Shared Key
encryptions, you can specify up to 4 keys and only 1
would be used at a time. We have the following
options:
Used Key Slot: Chooses between Key #1 to Key #4.
Key #1: Specifies a string of characters to be used as
the password. It may consist of 5 ASCII characters or
10 HEX characters, implying a 64-bit WEP key length.
Otherwise, it may consist of 13 ASCII or 26 HEX
characters, implying a 128-bit key length.
Key #2, #3, and #4: Similar to Key #1.
Note: Valid HEX characters are numbers 0-9 and
letters A-F, case insensitive. Valid ASCII characters are
numbers and the letters of the English alphabet, case
sensitive. Based on the number of characters, the key
is automatically checked for validity. Invalid keys are
represented by red dots while valid keys are
represented by black dots. Click the green arrows icon
beside the text field to reveal/hide the password.
WPA or WPA2 with PSK
Wifi protected access (WPA) is a stronger encryption
than WEP.
Furthermore, WPA2 was developed to strengthen the
security of WPA and is stronger than WPA and WEP.
For WPA-PSK, WPA2-PSK, WPA-PSK/WPA2-PSK Mixed
Mode encryptions, we have the following options.
Cipher: Can be set to Auto, CCMP (AES), or TKIP and
CCMP (AES). The Temporal Key Integrity Protocol
(TKIP) was developed as a temporary replacement for
WEP. The Counter Mode Cipher Block Chaining
Message Authentication Code Protocol (CCMP) is
based on the Advanced Encryption Standard (AES)
and is the most secure protocol.
Key: The pre-shared key (PSK) is the password for the
wireless network. This may consist of 8 to 63 ASCII
characters.
WPA or WPA2 with EAP
The Extensible Authentication Protocol (EAP) is
encapsulated by the IEEE 802.1X authentication
