Updating from
standard WP54 and WPP54 firmware to new multi-SSID firmware
|
|
Multi-SSID
firmware support for WP54 and WPP54 will be available from firmware v2.0 and
higher. |
|
Warning:
The
following wireless operation modes are changed in mSSID firmware. |
|
a) Pont to Point and Point to Multi-Point |
|
b) WDS (Wireless Distribution System) |
|
If APs are
configured and running these modes, updating to the mSSID firmware
will cause wireless disconnection. |
|
You need to connect
individually with each AP to update the mSSID firmware, and then
reconfigure them with new setup. |
|
Please see the
User Manual for setup instructions. |
|
The new
PtP and PtMP method in mSSID firmware is compliant with the IEEE 802.11h
standard. |
|
User does
not need to update to the mSSID firmware if their existing PtP and PtMP
modes are working properly for them, and the respective country
authority. |
|
|
Question: |
|
What is mSSID? |
|
Answer: |
|
Multi-SSID
(mSSID) as the name suggest, allows an access point (AP) with a single
radio card to support more than one SSID. |
|
|
|
Question: |
|
What can you do
with mSSID connection? |
|
Answer: |
|
The application of mSSID is to
provides better security with multiple network path connections from a single
AP, to multiple VLAN network segments of the switch on the local area network. |
|
A
network setup application is illustrated below. |
 |
|
E.g. |
|
Virtual AP
with SSID: VAP1, VLAN ID: 10, and WPA-PSK wireless security enabled will
be channeled to Port 2 and Port 3 where the internet-sharing router is
connected. |
|
Virtual AP with
SSID: VPA2, VLAN ID: 20, WPA-EAP enabled, and connected to a radius server,
will be channeled to Port 5 and Port 6, which are connected to the firewall
of the internal local area network. |
|
|
|
Question: |
|
Can I
update my WP54G or WP54AG to this mSSID firmware? |
|
Answer: |
|
Yes. You
can retain your WP54G or WP54AG configuration when you update to the
mSSID firmware if the current firmware running is v1.3x and above. |
|
If AP is running
the following configuration setup, updating to the mSSID firmware will affect
the configuration. |
|
a)
|
If AP is
running as PtP (Point-To-Point) or PtMP (Point-To-MultiPoint) mode. |
|
|
The
reason it cannot retain the configuration is because mSSID uses a new
PtP and PtMP connection setup method called: RootAP and Transparent
Client. This method is compliant with IEEE 802.11h standard. |
|
b) |
AP is running very
old firmware v1.2x and below. |
|
|
|
Question: |
|
Can I update to
mSSID firmware but setup only one SSID connection? |
|
Answer: |
|
Yes, mSSID
firmware operation is similar to previous single SSID firmware when
setup with one SSID. |
|
If the existing AP
is running v1.3x firmware, after updating to mSSID it will retain and continue
to run the previous configuration. No reconfiguration is needed. |
|
|
|
Question: |
|
I have a MAC
Filtering table set from a previous firmware. Will updating to mSSID cause
the MAC table to be lost? |
|
Answer: |
|
No, if
your firmware is v1.3x and higher, updating to mSSID firmware will
retain all entries in the MAC table. |
|
However, if you
switch back from mSSID to the previous sSSID firmware, the MAC table will be
lost. |

However, if you
switch back from mSSID to the previous sSSID firmware, the MAC table will be
lost. |

|
|
Question: |
|
I
have Pseudo VLAN for Per Group enabled. Will updating to mSSID firmware
still support wireless clients with MAC addresses listed in Per Group? |
|
Answer: |
|
The mSSID firmware
replaces Pseudo VLAN and integrates it into VAP (Virtual AP) and MAC Filtering. |
|
Thus,
Pseudo VLAN with its VLAN ID and MAC listing will be lost after updating
to mSSID firmware. |
|
Refer to the
user manual on how to create new VAP with VLAN ID and MAC Filtering. |
|
Similarly,
Per Node (control to isolate wireless station in AP) being part of
Pseudo VLAN will also be lost. |
|
|
|
Question: |
|
I
have WDS setup in my network. Will mSSID still support this? |
|
Answer: |
|
WDS has
the limitation that it can only support WEP security key. To support
higher wireless security it is replaced with Repeater mode in mSSID
firmware. Thus, updating to mSSID will disconnect the WDS links and
connections with the rest of the APs. It is recommended to connect
directly to each AP to update the firmware, then set to Repeater mode
and configure it before updating the next AP. This way you can build
back the connections. Refer to the user manual for more details
instructions on the setup. Updating to the mSSID firmware is not
necessary if you do not need the higher wireless security support. |

|
Question: |
|
I have 2
WP54AG units installed at a site about 2km from each other running PtP modes.
Should I update to mSSID firmware? Can I do it from one location to update the
firmware like I do with the current single SSID firmware?
|
|
Answer: |
|
The setup for PtP
and PtMP for mSSID firmware is different the current sSSID firmware. After mSSID
firmware starts up, the link between the 2 APs will be lost. The recommended
method is to setup 2 similar model units in the office. Load the mSSID firmware
and create the new PtP / PtMP configuration using the actual parameters of the 2
units on site that you will update. |
|
After
testing the connection to be working in the office, backup the
configuration file for each unit. Go to the first site to update the
mSSID firmware and restore the configuration for the site, then go to
the next site and do the same. When both APs are up again, the network
at both sides should be connected with the new PtP setup. |
|
**
Note: If existing PtP connection is running well, it is not necessary to
update to the mSSID firmware.
|
|
Unless you have the following concerns: |
|
a)
|
Current
firmware PtP is not compliant with IEEE 802.11h standard and the
respective country authority requires it to be changed. |
|
b) |
Current
firmware PtP wireless security only supports WEP key and you are very concerned
about the vulnerability to being hacked. |
