Disable SSID broadcast
(AP only)
This should be used to prevent unwanted eavesdroppers from detecting
the radio network system address (SSID) by passively listening to beacon
transmissions from the access point. When disabled, access points will not
transmit the system address openly in beacon messages. This is particularly
useful in unencrypted radio networks.
3 Address Mode
Allows compatibility with Layer 3 Bridge devices. See “3.6 Compatibility.”
Save Changes
Save changes to non-volatile memory. Changes will not take effect until module
is reset.
Save Changes and Reset
Save changes to non-volatile memory and reset module.

the modem will select the best channel based on signal level and channel density. Channel can also be
manually selected by picking the channel number from the list. Available channels 1-11 are 20 MHz,
channels 41-51 are 10 MHz and channels 21-31 are 5 MHz. Turbo channels can are also be selected
depending on the country.
Figure 37 2.4GHz Channel Selection
245U-E-A Modem (5 GHz 802.11a)
You can select an individual channel from the list, keeping in mind that the channel will have some transmit
and/or DFS constraints, as indicated in “3.1 Selecting a Channel” and “Appendix C - CHANNELS.” If using
the Auto mode, you will need to select the appropriate groups that you wish to use and the modem will
automatically select an available channel from within the selected groups.
