These operations should be manually performed without WPS. To establish a connection, the user simply
needs to press the WPS button located on the side panel of the device or use web configuration to enter a PIN
code.
WPS Setup
– Enable WPS – to enable WPS, select Enable in the drop-down list if WI-FI network adapter of your
device supports this configuration mode;
– Add Client– client authentication method (the settings are applicable in the WPA-PSK and WPA2-PSK
modes only). Click the Add Enrollee button to start the authentication process.
– Use STA PIN – authentication using client PIN code;
– Set Authorized Station MAC – sets MAC address of the client device in ХХ format:
ХХ: ХХ: ХХ: ХХ: ХХ:
– Use AP PIN – authorization using own PIN code;
– Set WPS AP Mode—set the WPS mode of the access point;
– Device PIN – device own PIN code (an 8 -digit code generated by the device).
Disadvantages of WPS
Wi-Fi routers supporting WPS technology have a network security vulnerability. The
vulnerability can be used to crack passwords of the WPA and WPA2 encryption protocols. It involves
bruteforcing of the 8-digit network key (PIN code).
Manual Setup AP:
– Select SSID—select a name of a wireless network from the list;
– Network Authentication—select a network authentication mode from the drop-down list:
– open—without wireless network security features (only WEP key can be used in this mode);
– Shared—this mode enables user authentication by their SSID or WEP key;
– 802.1x—enables 802.1x standard (enables user authentication with a RADIUS server; WEP key is
used for data encryption);
 RADIUS Server IP Address—IP address of the RADIUS server;
 RADIUS Port—port number of the RADIUS server. The default port is 1812;
 RADIUS Key—secret key for access to the RADIUS server;
– WPA2—enable WPA2 (this mode uses WPA2 protocol and requires a RADIUS authentication
server);
 WPA2 Preauthentication;
 Network Re-auth Interval;
 WPA Group Rekey Interval—the period of time (in seconds) between automatic
changes of WPA encryption keys; used to strengthen wireless network security. If
no key changes are required, set this field to 0.
 RADIUS Server IP Address—IP address of the RADIUS server;
 RADIUS Port—port number of the RADIUS server. The default port is 1812;
 RADIUS Key—secret key for access to the RADIUS server;
 WPA/WAPI Encryption—select a WPA/WAPI data encryption method: TKIP+AES,
AES:
– TKIP—encryption protocol for WPA. It enables more efficient
management of key changes compared to WEP;
