authentication mode. This ignores the stored SSID and searches
for the access point with the strongest signal. The channels
searched can be limited by setting the channel mask.
3
Reserved – Not used.
4
Create an Ad hoc 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 Ad hoc device can
act as DHCP server). This policy is often used instead of the
hardware jumper to create a custom Ad hoc network.
7
Create a soft AP network using stored SSID, IP address, netmask,
channel, etc. This mode applies only to firmware version
supporting soft AP mode and not ad hoc mode.
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.
set 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 passphrase
command. Key must be EXACTLY 13 bytes (26 ASCII chars). Data is expected in HEX format, leading “0x”
should NOT be used here.
Example :
set w k 112233445566778899AABBCCDD
Hex digits > 9 can be either upper or lower case.
The WiSnap 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, WiSnap will scan once per second for
the AP it is associated with. The value is the threshold of failed scans before the WiSnap declares “AP is Lost”, de-
authenticates. The WiSnap 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 enabling this feature, there is no way to detect if 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 to ‘password’.
