–
802.11bgn
– if the network has Wi-Fi clients with 802.11b, 802.11g and 802.11n
support.
–
Security options
– select security mode of wireless network:
–
Off
– disable encryption to transmit data (low security level);
–
WEP
– WEP algorithm – when this type of authentication is selected, you must
enter security keys:
–
WEP Keys
– You can enter up to two different keys of 10 or 26 hexadecimal digits,
or 5 or 13 ASCII
1
characters. To select a key, check the corresponding box. Using
WEP is not recommended due to security flaws related primarily to its encryption
weakness and lack of any user authentication mechanisms. The key problem of
WEP is that it uses highly similar keys for different data packages;
–
Use WPA only
– use only WPA standard. WPA uses TKIP, MIC and 802.1X
algorithms, it significantly increases security of the standard in relation to WEP;
–
Use WPA2 only
– use only WPA2 standard. CCMP and AES are realized in WPA2
thereby WPA2 became more secured in opposite to WPA. Take into account that it
is recommended to use this secure algorithm;
–
Use WPA and WPA2
– use security algorithm WPA and WPA2.
When you select any type of WPA authentication the following settings will be available for editing:
–
Authentication mode
– select authentication method – secret phrase (password) or key access:
–
Secret phrase
– encryption key is a string with length from 8 to 63 ASCII symbols;
–
Secret WPA key (Key)
– set key with 64 characters of hexadecimal number system;
–
Authorization on a RADIUS-server
–
when checked, use authorization on a RADIUS-server. When
the parameter is selected, the following settings will be available for editing:
–
Server Address
–
domain name or IPv4 address of authorization server;
–
Server Port
–
server port for authorization;
–
Secret key
–
secret key for access to server of authorization;
–
Authentification algorithm
–
select authorization algorithm
(MSCHAPv2, MSCHAP,
CHAP, PAP);
Username for client authentication on RADIUS server is equal to its MAC address
(lowercase letter without separator symbols between bytes) and key of RADIUS server is
used as password.
1
ASCII is a set of 128 characters for machine representation of capital and lower case Latin characters, digits, punctuation
marks, and special symbols.
