SSL Issuer Entity issuing the CA certificate.

SSL Subject Subject from the CA certificate.

SSL Start Date Date the SSL certificate is valid.

Encryption Type The type. 64–bit WEP, 128–bit WEP, Dynamic (used with WEP, TKIP, or both), Auto,

or None (no encryption is used)..

Dynamic Type Indicates whether dynamic encryption is used. Disabled, Shared (pre-shared keys), or

Robust (TKIP or AES)

Available Wireless Networks Lists the available wireless networks, and their properties which include the SSID,

Wireless Mode The 802.11 wireless mode, which are B/G or B/G/N.

Guard Interval The guard interval setting (Auto, Long or Short) which is the space between

transmitted symbols (characters). Can eliminate inter-symbol interference (ISI), which

occurs when echoes or reflections from one symbol interfere with another. A long

interval can reduce echoes, but decrease the data rate. A short interval can increase

the data rate by approximately 10 percent.

AMSDU Aggregation Aggregating 802.11n MAC service data units packs them into frames to reduce

overhead and increase the data rate. Enabling aggregation allows a maximum frame

size of 7935 bytes. Use aggregation of MAC service data units: ENABLED or

DISABLED

Block ACKs Select whether to enable acknowledgment of multiple AMPDUs, which allows each of

the aggregated data frames to be individually acknowledged or retransmitted if

affected by an error. (Automatically enabled when AMPDU Aggregation is enabled.)

Use block acknowledgement of multiple AMPDUs: ENABLED or DISABLED

AMPDU Aggregation Aggregating 802.11n MAC protocol data units packs them into frames to reduce

overhead and increase the data rate. Enabling aggregation allows a maximum frame

size of 64k bytes: ENABLED or DISABLED
