set wlan join <value>
sets the policy for automatically joining/associating with
networkaccess points. This policy is used when the
module powers up,including wake up from the sleep
timer.
Value Policy
0 Manual, do not try to join automatically
Try to join the access point that matches the
1 stored SSID, passkey and channel. Channel
can be set to 0 for scanning. (Default)
Join ANY access point with security matching
the stored authentication mode. This ignores
the stored SSID and searches for the access
2
point with the strongest signal. The channels
searched can be limited by setting the channel
mask.
3 Reserved – Not used
Create an Adhoc network, using stored SSID,
IP address and netmask. Channel MUST be
set DHCP should be 0 (static IP) or set to
Auto-IP with this policy. (unless another Adhoc
4
devicecan act as DHCP server)
This policy is often used instead of the
hardware jumper to creat a custom Adhoc
network
set wlan hide <0, 1>
Hides the WEP key and WPA passphrase. When set,
displaying the wlan settings shows ****** for these
fields. To unhide the passphrase or passkey, re-enter
the key or passphrase using the set wlan key or set
wlan passphrase command. Default = 0, don't hide.
wlan key <value>
sets the 128 bit WEP key. If you are using WPA or
WPA2 you should enter a pass phrase with the set
wlan passphase command. Key must be EXACTLY 13
bytes (26 ASCII chars). Data is expected in HEX format,
"0x" should NOT be used here.
Example : "set w k 112233445566778899AABBCCDD"
Hex digits > 9 can be either upper or lower case.
The ATC-2000WF only supports "open" key mode, 128
bit keys for WEP.WEP-128, shared mode is not
supported as it is known to be easily compromised and
has been deprecated from the Wi-Fi standards.
set wlan linkmon <value>
sets the link monitor timeout threshold. If set to 1 or
more, ATC-2000WF will scan once per second for the
AP it is associated with. The value is the threshold of
failed scans before the ATC-2000WF declares "AP is
Lost",de-authenticates. The ATC-2000WF will retry the
association based on the join policy variable. A value of
5 is recommended, as some APs will not always
respond to probes. Default is 0 (disabled). Without this
feature, there is no way to detect an AP is no longer
present until it becomes available again (if ever).
set wlan mask <value>
sets the wlan channel mask used for scanning
channels with the auto-join policy 1 or 2, used when the
channel is set to 0. Value is a bit-map where bit 0 =
channel 1. Input for this command can be entered in
decimal or hex if prefixed with 0x. Default value is
0x1FFF (all channels)
set wlan num <value>
sets the default WEP key to use. 1-4 is the valid range.
Example : "set w n 2" sets the default key to 2.
set wlan phrase <string>
sets the passphrase for WPA and WPA2 security
modes. 1-64 chars.The passphrase can be alpha and
numeric, and is used along with the SSID to generate a
unique 32 byte Pre-shared key (PSK), which is then
hashed into a 256 bit number. Changing either the
SSID or this value re-calculates and stores the PSK.
If exactly 64 chars are entered, it is assumed that this
entry is already an ASCII HEX representation of the 32
byte PSK and the value is simply stored.
For passphrases that contain spaces use the
replacement character $ instead of spaces. For
example "my pass word" would be entered
"my$pass$word". The replacement character can be
changed using the optional command set opt replace
<char>.
Example : "set w p password" sets the phrase.
set wlan rate <value>
sets the wireless data rate. Lowering the rate increases
the effective range of the ATC-2000WF module. The
value entered is mapped according to the following
table.
Value Wireless Data Rate
0 1 Mbit/sec
1 2 Mbit/sec
2 5.5 Mbit/sec
3 11 Mbit/sec
4-7 Invalid
8 6 Mbit/sec
9 9 Mbit/sec
10 12 Mbit/sec
11 18 Mbit/sec
12 24 Mbit/sec (default)
13 36 Mbit/sec
14 48 Mbit/sec
15 54 Mbit/sec
