WDR-3124A Web Console Configuration

3-16

Security mode

Setting Description Factory Default

Open No authentication Open

WEP Static WEP is used

WPA WPA is used

WPA2 Fully supports IEEE802.11i with “TKIP/AES + 802.1X”

Open

For security reasons, you should NOT set security mode to Open, since authentication and data encryption are

NOT performed in Open security mode.

WEP (only for legacy mode)

NOTE

Moxa includes

WEP security mode only for legacy purposes. WEP is highly insecure and is considered fully

deprecated by the Wi

-Fi alliance. We do not recommend the use of WEP security under any circumstances.

According to the IEEE802.11 standard, WEP can be used for authentication and data encryption to maintain

confidentiality. Shared (or Shared Key) authentication type is used if WEP authentication and data encryption

are both needed. Normally, Open (or Open System) authentication type is used when WEP data encryption is

run with authentication.

When WEP is enabled as a security mode, the length of a key (so-called WEP seed) can be specified as 64/128

bits, which is actually a 40/104-bit secret key with a 24-bit initialization vector. The WDR-3124A provides 4

entities of WEP key settings that can be selected to use with Key index. The selected key setting specifies the

key to be used as a send-key for encrypting traffic from the AP side to the wireless client side. All 4 WEP keys

are used as receive-keys to decrypt traffic from the wireless client side to the AP side.

The WEP key can be presented in two Key types, HEX and ASCII. Each ASCII character has 8 bits, so a 40-bit

(or 64-bit) WEP key contains 5 characters, and a 104-bit (or 128-bit) key has 13 characters. In hex, each

character uses 4 bits, so a 40-bit key has 10 hex characters, and a 128-bit key has 26 characters.
