3.5.2.1 Limitations
When running in the multiple repeater mode, the following limitations apply:
©
VAP configuration after start is subject to the conditions specified in
section 3.4.3 and section 0.
© Use the environmental variable method to configure the VAPs.
3.5.2.2 Setup Instructions
This configuration is set up in the same manner as the previous configuration. Note that each repeater must have a
unique IP address, on the same subnet. The SSID for both repeaters, as well as the Root AP must be identical to form a
BSS. The root AP controls the security mode, so ensure both repeaters are set up to be consistent with the Root AP.
Ensure that the repeaters have the AP_STARTMODE environmental variable set to “repeater”, as shown in section
3.5.1.2. The root AP is configured with the same setup as in section 3.5.1.2. The AP’s can be started in any order. To
ensure that the repeater stations associate to the root AP (and not each other, since they are using the same SSID), define
the ROOTAP_MAC environmental variable in the form xx:xx:xx:xx:xx:xx. This is required to force association to the
root AP. This is only required in this situation where multiple repeaters have the same SSID, and may accidentally be
closer than the root AP to another repeater AP.
3.5.3 WDS Bridge with single span
This configuration is a wireless bridge between two Ethernet subnets. This configuration uses the WDS feature to
provide the bridging. Client stations can either be attached to one of the two Ethernet subnets, or can associate directly
with the Root AP. The latter case is not typically tested in this configuration, but is not disallowed. This situation is
different from the repeater mode in that the Station node does not also have an AP VAP, so no station can associate with
the station (no Ad-Hoc allowed). This makes either the WDS link, or the Ethernet links the only way traffic enters/exits
the AP.
This solution is typically used in cases where the user wants to join subnets that are located a distance from each other,
or in a home situation where it is preferable not to run wires between rooms. Only one of the servers on this network
should be serving DHCP addresses – typically the Root AP.
3.5.3.1 Limitations
When running in the WDS Bridge mode, the following limitations apply:
©
VAP configuration after start is subject to the conditions specified in
section 3.4.3 and section 0.
© Use the environmental variable method to configure the VAPs.
