Minimum Receive
Threshold
/interface/wifi-<n>-<m>/set rcv-rssi-threshold <dBM_threshold>
{disabled | enabled}
This command sets a minimum signal strength threshold to prevent associations
with weak radio signals. Associations are only created between radios with a
signal strength greater than the specified threshold.
The default setting is
disabled
.
802.11b
Protection
/interface/wifi-<n>-<m>/set b-protection {disabled|enabled}
This command enables or disables 802.11b protection for the radio. Normally,
an 802.11g AP uses CTS-to-self to interact with 802.11b APs. The transmitted
packet is small, but in High Capacity and Interference environments the
accumulated effect is a substantial performance penalty. This feature disables
802.11b protection for the radio, maximizing the throughput for wireless clients
that operate in the 2.4 GHz range.
This feature improves performance if there are only a few 802.11b clients
present and they are not generating large amounts of traffic. If not, the 802.11b
clients may generate substantial numbers of collisions and actually impair traffic.
The default setting is
disabled
.
ARP Filtering
/interface/wifi-<n>-<m>/set arp-filtering {disabled|enabled}
This command enables or disables ARP filtering. When enabled, the radio only
forwards the ARP packet (request) to a currently connected client. Otherwise,
the downstream ARP requests are dropped.
The default setting is
disabled
.
Changing Wi-Fi
Interface Admin
State
/interface/wifi-<n>-<m>/set admin-state {enable|disable}
This command controls the state of the Wi-Fi interface including all links.
When set to
enable
, the Wi-Fi interface is in the operational state. When set to
