Specifies a signal strength below which the radio will not select a
different Parent radio. You can use this in Fast Roam applications
where the radio is on a mobile platform, or there is a lot of movement
in the environment causing RSSI levels to fluctuate. The radio keeps
its current Parent radio unless another Parent radio's RSSI is stronger
than this value. The radio adds this margin value to the current Parent
radio's RSSI prior to calculating its cost. It is desirable to Roam to a
new Parent radio before losing the connection with the current Parent
radio, since losing the connection results in data loss.

If you enter a value that is too small, it can lead to the radio
rapidly switching back and forth between two Parent radios as the
RSSI levels change.

If you enter a value that is too large, it can result in preventing a
Roam until the radio moves out of range, even though a
candidate exists that is actually better than the current Parent
radio.
The default value is 5 dB.

Use larger values (10-15 dB) to prevent false roams from
occurring due to temporary RSSI inversions between the current
Parent radio and another candidate.

Make sure that that when Roaming that the RSSI difference
between the current Parent radio and the new Parent radio is
greater than this value.
Specifies how the radio selects the rate to the Parent radio.
A - The default setting. The radio selects the best rate to use to the
UTO
Parent radio, and adapt over time.
F R - Fixes a lower rate to improve performance; for example if
IXED ATE
the link to the Parent radio has a low signal strength.
The actual rate used between this radio and its Parent radio is the
lower value of this setting and the Max Data Rate setting in the Parent
radio. So use R P
ATE TO ARENT
Parent radio in conjunction if you want to customize the rate of each
parent link. See Advanced Wireless Settings (page 78).
Note: When configuring an RLX2-IHNF, this parameter is only
enabled if the 802.11 M
ODE
set to 802.11 / mode. See Basic Wireless Settings (page 65).
A G
Specifies whether the Repeater radio acts as a Parent radio to other
802.11 radios.
Y - Allows this radio to be a Parent radio to other 802.11 radios.
ES
- Disguises the radio's SSID to prevent other 802.11 devices from
N
O
finding it. This is useful in Fast Roam applications where you do not
want any other devices connect to a Repeater radio that moving and
roaming.
