Firmware 3.28 release notes
Zonda Module Numbers: WLNN-AN-TX551
Resolved Issues:
WI6743 Behavior change to pass mode functionality requested by Total Trax. The behavior of
the device when a pass command was issued differs between different generations, and version
numbers of the device. We added a command “wl-tunnel-msg-type” that can be set to 0 or 1.
The default value is 1. For total trax they now get an OEM config file that sets the value to 0.
The main differences between the 2 are: value 0 sends OK on inactivity timeout, and value 1
sends timeout error, and value 0 sends an error message when the server disconnects the tunnel.
Firmware 3.27 release notes
Zonda Module Numbers: ADBN-ER-DP551
Resolved Issues:
WI6675 Fixed issue which allows the webpage and cli to set the “wl-region” to be Spain (ES).
Firmware 3.26 release notes
Zonda Module Numbers: ADBN-SE-HA5532
Resolved Issues:
WI5694 Added command “wl-tunnel-timeout-mode” the inactivity timeout configured by wltcp-timeout when it breaks out of the current connection will either attempt to re-connect to the
server, or break out of bridge into the cli. The socket used in version 3.25 was not being
properly closed on timeout, and would use the still open socket on re-connect. 3.26 closes the
socket and continually attempts to connect via a new socket connection.
WI4767 Improved roaming to 5GHz DFS channels. Background scans are performed by the
device on each channel once a minute. DFS channels require the device to not send unless the
device sees a beacon, so the background scanning of these DFS channels just listen for a beacon.
With the previous time allocated to listen to these channels an AP producing beacons every
100ms was frequently missed. The listen time is now set to 200ms.
Firmware 3.25 release notes
Zonda Module Numbers: ADBN-SE-HA5532
Resolved Issues:
WI5694 Added command “wl-tunnel-timeout-mode” the inactivity timeout configured by wltcp-timeout when it breaks out of the current connection will either attempt to re-connect to the
server, or break out of bridge into the cli.
Firmware 3.23 release notes
Zonda Module Numbers: WLNN-AN-AD551
Resolved Issues:
WI 4089, added Line Printer Daemon (LPD) a linux utility that processes network printing
requests. Our implementation of it will send the print request without filtering out a serial port to
be printed on a serial printer. There are 4 new commands to control this feature:
“lpd-enable” Enables or disables the line printer daemon (LPD).
0 = disabled (default)
1 = enabled
“lpd-port” The TCP/IP port that LPD will be listening on. The default is 515.
“lpd-serial-port” The serial port that LPD will send the printing data to.
p1 = Serial Port 1 (default)
p2 = Serial Port 2
“lpd-spool-name” An arbitrary string that identifies the name of the spool/queue that is used to
print to the printer setup on the module.
Firmware 3.22 release notes
Zonda Module Numbers: WLNN-ER-DP551, WLNN-AN-DP551, WLNN-SE-DP551, WLNN-SP-DP551, WLNN-EK-DP551, APMNQ551
Resolved Issues:

When in AP mode with wpa or wpa2 security “wl-acl-policy” will not take effect.

Improved stability when updating firmware. The module will report failures when they occur;
when an error occurs attempt to reprogram up to 5 times without cycling power. If failures
continue return for RMA. If attempting to update a previous version of firmware use Ethernet
port as the interface to update the firmware.

When the module uses a static IP address, including a fallback address when DHCP is enabled
(and not successfully obtained). A gratuitous arp will be sent with the address the module is
going to use.

When “wl-mac-clone” is set in bridge mode not all packets were using the cloned MAC address.
Particularly in enterprise security mode.

New Feature: support for DHCP option 225 to be a list IP addresses. The option can be added to
the parameter request list with command “wl-dhcp-opt225-enable”. The IP addresses reported
by the DHCP server can be obtained via command “wl-dhcp-opt225”. The format of the IP
addresses will be returned as an ascii string of characters in decimal value “xxx.xxx.xxx.xxx”, with
a space in between each IP address. The default to “wl-dhcp-opt225-enable” will be disabled. If
no response has been received yet, or an invalid response is received for DHCP option 225 “wldhcp-opt225” will return “Empty”.

DHCP packets in bridge mode had the broadcast flag forcibly set. Added the command “brdhcp-broadcast-flag” to allow the user to disable this feature. Default value of “br-dhcpbroadcast-flag” will be enable

New feature: added wl-rate-specifics command. This command can override the standard rates
supported in the wireless driver to specify a set of specific rates. This command accepts a hex
string and the bit map of that hex string will be set as the supported rates. Also note that
generic rates (1, 2, 5.5, and 11) must be supported, so they will be supported unless the AP
reports support for less. A value of 0 will disable this feature and cause the normal rate
selection to be performed.
bit 0x000001 = 1 Mbps
bit 0x000002 = 2_Mbps
bit 0x000004 = 5.5_Mbps
bit 0x000008 = 11 Mbps
bit 0x000010 = 6 Mbps
bit 0x000020 = 9 Mbps
bit 0x000040 = 12 Mbps
bit 0x000080 = 18 Mbps
bit 0x000100 = 24 Mbps
bit 0x000200 = 36 Mbps
bit 0x000400 = 48_Mbps
bit 0x000800 = 54_Mbps
bit 0x001000 = MCS0 HT20
bit 0x002000 = MCS1 HT20
bit 0x004000 = MCS2 HT20
bit 0x008000 = MCS3 HT20
bit 0x010000 = MCS4 HT20
bit 0x020000 = MCS5 HT20
bit 0x040000 = MCS6 HT20
bit 0x080000 = MCS7 HT20
Default is 0.
Known Issues:

When in AP mode, the 10th connected client doesn’t get displayed when “wl-clients” is issued.

The command “wl-max-retries” doesn’t work properly when in AP mode. Up to 20 retries can
be seen, regardless of the configured value.

Implementation of Diversity for the AR6203 is incomplete. For this firmware revision,
the configuration “wl-ant d” is equivalent to the default “wl-ant 2”.
