If “Off”, WiFi is without any security, i.e. anybody can be connected and access your RipEX
web pages.
■ WPA2-PSK
A Short for Wi-Fi Protected Access 2 - Pre-Shared Key. It is a method of securing your network
using WPA2 with the use of Pre-Shared Key (PSK) authentication. To encrypt a network
with WPA2-PSK you provide your router not with an encryption key, but rather with a plain-
English passphrase between 13 and 64 characters long. Using a technology called TKIP (for
Temporal Key Integrity Protocol), that passphrase, along with the network SSID, is used to
generate unique encryption keys for each wireless client. And those encryption keys are
constantly changed.
•
WPA2 PSK Key - The string (13-64 characters) which is used for WPA2 encryption key
generating.
The following characters are not allowed in the key:
" (Double quote)
` (Grave accent)
\ (Backslash)
$ (Dollar symbol)
; (Semicolon)

• Parameters
List box: Default, Manual
Default = Default
Default – Default (recommended) values are set and can not be edited.
Manual – Values can be set manually.
There are 2 tables with diagnostic information in the main menu - Diagnostic/Neighbours, Diagnost-
ic/Statistic. The Neighbours table displays Watched values from RipEX and from all its neighbours.
(Neighbour = RipEX, which can be accessed directly over the radio channel, i.e. without a repeater).
There is statistic information about the traffic volume in the Statistic table.
○
Watched values broadcasting period [min]
Default = 120 min, [0 = Off]
RipEX periodically broadcasts its Watched values to neighbouring units. The Watched values
can be displayed in Graphs and Neighbours menu.
Note : When Bridge mode is used, watched values broadcasting creates collisions for user traffic.
Be careful in using this feature.
