 802.11b – if all the Wi-Fi clients support standard 802.11b;
 802.11bg – if network has Wi-Fi clients with 802.11b and 802.11g support;
 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
8
. 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 implemented 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 any type of WPA authentication is selected, the following settings will be available for
editing:
- Authentication mode – select authentication method – secret phrase (password) or key
access:
