ap-config - configure and monitor Atmel and NWN based APs
ap-config
ap-config to config and get stats from Atmel-chipset based AP with ATMEL
Private MIB support.
Info/
- SysInfo
- Get info about AP hardware and software
- Ethernet
- This option displays the Ethernet statistics for your
reference.
- Wireless
- This option displays the wireless statistics for your
reference.
- Stations (atmel)
- Under this menu the user will be able to see the Associated
Stations that are currently associated with the Access Point. For each
associated station the user will be able to see the MAC Address. From
version 0.7.3-pre1 you may save mac addresses list to file
~/<util_name>.stations. Stations on NWN AP: For each associated
station the user will be able to see the MAC Address, Link Quality, RSSI
and Idle time.
* Mac address: If the association is pending (that is, the Client is
scanning, authenticating or associating), assocAddress contains the MAC
address of that Client with the group bit set to indicate that the Access
Point is aware of the presence of that Client. The other objects of the
entry will be updated based on the information extracted from the received
Probe Requests.
* Link Quality: An indicator for the quality of the Client. If the
association is still pending, the quality is calculated over the received
Probe Requests from the Client. If the Client is associated, the quality
derived from any activity with the Client. The actual quality source
depends on the selected quality indicator. The semantics of the indicator
is 'low is good quality' and 'high is bad quality'.
* IdleTime: An indicator (in seconds) for the age of the information on the
Client. The age is reset to 0 if any activity of this Client is detected.
* RSSI: An indicator for the RSSI of the Client. If the association is
still pending, the RSSI is calculated over the received Probe Requests
from the Client. If the Client is associated, the RSSI derived from any
activity with the Client.
- KnownAP
- By using option APs from info menu you may see all Access
Points thats visible by your AP.
* Link Quality: An indicator for the quality of the Client. If the
association is still pending, the quality is calculated over the received
Probe Requests from the Client. If the Client is associated, the quality
derived from any activity with the Client. The actual quality source
depends on the selected quality indicator. The semantics of the indicator
is 'low is good quality' and 'high is bad quality'.
* RSSI: An indicator for the RSSI in dBm of the Client. If the association
is still pending, the RSSI is calculated over the received Probe Requests
from the Client. If the Client is associated, the RSSI derived from any
activity with the Client.
* WARNING! By reports this option my be dangerously - in some cases you may
lost you AP configuration and on SMC2655W the one way to fix it - only
restore factory defaults.
Config/
- Bridging
- IP configuration - If the server site supports DHCP
function and the DHCP Enable box is ticked; the IP address of an access
point will be automatically displayed and assigned; otherwise, you need to
key in an IP address now. The primary port provides a wired or wireless
method to change the access point setting. If the Ethernet option is
ticked, the setting of an access point can be done through Ethernet. If
the Wireless option is ticked, the access point function can be set
through a wireless station. Wireless station means a laptop PC or a
desktop PC equipped with an IEEE802.11b PCMCIA card or USB dongle. Enable
SNMP Traps enables the SNMP trap function. You can view the records by
using ap-trapd utility. You are allowed to set your access point to be
used as Access point, Access point client, or Wireless bridge.
* Access Point - An internetworking device that seamlessly connects wired
and wireless networks together.
* Wireless bridge Point to point - The point-to-point wireless bridge
configuration uses two Wireless Bridge units to connect two separate LANs.
You must to fill in the Remote MAC Address before your
bridge-function-enable access point can work with it.
* Point to multipoint - When connecting three to more separate LANs, each
LAN located building requires a wireless bridge. This is called Multipoint
wireless bridge and again requires one Master bridge unit and two or more
Slave bridge units as required. If the point-to-multipoint option is
selected, your bridge-function-enable access point will designate as a
Mater and to work with it, others bridges need to be set as a
point-to-point bridge and enter the MAC address of the mater access
point.
- Wireless
- You can give your access point a name and give it an ESSID
(Extended Service Station ID), which can allow other wireless stations,
which knows the ESSID, to link with it.
- Privacy
- The Privacy options allow you to enable 64-bit or 128-bit
WEP (wired equivalent privacy) encryption. If an encryption function is
not needed, you can just simply tick on the Disable box to disable it. If
the 64-bit or 128-bit encryption function is enabled, there are four sets
of key need to be filled into the blanket boxes. For the 64-bit
encryption, each key is required to enter 5 Hex digits. For example: 11 22
33 44 55. The 128-bit encryption requires each key to enter 13 Hex digits.
For example: 12 34 56 78 9A BC DE F0 11 22 33 44 55.
NOTE! The WEP keys you enter are really accepted and written to the AP,
permanently if you do an Upload from the Commands menu after setting them.
However, the new key values are not echoed to the user when you return to
the Privacy settings under the Config menu. This is a security feature of
SNMP implementation in this hardware.
- Authorized MAC address
- For security or management purpose, you can edit a list of
authorized MAC addresses, which are allowed to view or modify the setting
of an access point. Authorization Table Enable option allows you to enable
or disable this function.
- Community
- The Community configuration allow you to set a phrase for
administrator and manufacturer community and a phrase for user community.
If a user knows the phrase of administrator, he/she is authorized to
change the setting of an access point. If a user only knows about the
phrase of a user community; he/she is allowed to view the setting of an
access point but is not allowed to change the setting.
- Radio
- Under the Radio user will be able to set or get the
Transmitting Powervalues, for the Control Register 31 of the Baseband, for
each channel. Reg CR31: Under this option user defines a value for the
transmitted power (Value for the Control register 31 of the baseband) and
it must be in the range 128 (max) to 255 (min) in Decimal form. Starting
from version 0.6 of Access Point SNMP Config utility it's possible to set
power output level for your AP. You may set signal power output in range
from 0mw to 100mw by setting value for corresponding channel from 0 to 255
(0xFF). The scale is as follows:
Value: 00----------128--------255
Power: 0mw--------100mw-------0mw
So to get maximum power output from your AP set value for corresponding
channel to 128 (0x80). But sometimes better solution - experimentally
choose values for best link quality, sometimes not max. More info you can
get from:

- Advanced
StationDBTimeout: This object specifies a timeout on entries and their state
information in the Station database. For Clients the Station database is
mapped on the roamTable. For Access Points, the Station database is mapped on
the assocTable. The timeout is in seconds.
ACKWindow: The ACK frame time out defined in number of slottimes. This can be
used to optimize long range links.
Commands/
- Upload
- After you ve changed any value or setting of an access
point through the SNMP config utility. You must come back to this option
to make the new changes and setting s validated. Also, only an
administrator and manufacturer is allowed to do such changes.
- Defaults
- Restore factory default configuration.
- Reset
- Reset AP. All changed and not uploaded settings will be
lost.
- TestMode/
- When user selects the Tests option a form will appear
indicating a number of parameter needed to be set by the user in order to
perform the Radio test.
Antenna: Under this option we specify the antenna to be tested (A, B).
Tx Filter: Under this option user needs to select the Baseband transmitting
Filter to be used. There are two options (US, JPN) available since the
bandwidth for Europe - USA is 11MHz and for, Japan is 14MHz.
Rate: Under this option user needs to specify the rate to be used among the
following options 1Mbps, 2Mbps, 5.5Mbps and 11Mbps.
Channel: Under this option user needs to select the channel to be used.
There are 14 channels available. After setting the parameters there are
three commands available: Continuous Tx (with modulation), Continuous Tx
(without modulation) and Continuous Rx:
* Continuous Tx (with modulation): Using this command the MAC sets the
transmitter in continuous mode with modulation. We can measure the output
power of the radio.
* Continuous Tx (without modulation): Using this command we can measure the
frequency accuracy of the radio. The MAC sets the baseband Processor in
test mode and turns off the spreading and scrambling codes.
* Continuous Rx: With this command user can set the device in a receiving
mode.
Note: In order to perform the above test user needs to have a Spectrum
Analyzer connected.
- Connect/
- In order to make a connection with Access Point user needs
to set two parameters. The IP Address of the Access Point and the
Community name (default 'public').
- Search/
- Find connected Access Points. Search for WNW APs only works
if community set to right AP community. It's useful if you know community
but dont know what ip your AP got from DHCP server. You must have support
for multicasting enabled in kernel.
- About/
- About function shows the Wireless Access Point Configurator
for Unix version and short info.
- Shell/
- Run subshell. To return type 'exit'
In case you unable to use cursor keys to menu navigate - try to use
"h" to go left, "j" to go down, "k" to go up,
"l" to go right, like vi editor.
