AmbiCom WL250N-USB Network Card User Manual


 
Item Name Description
Authentication
Type
Please select a wireless authentication type you wish to use. Available options are
‘Open’, ‘Shared’, WPA-PSK’, ‘WPA2-PSK’, and ‘WPA-PSK / WPA2-PSK’. If you want
to disable wireless data encryption, you must select ‘Open’.
Encryption Type Please select an encryption mode. The available options in this setting item will vary
depending on the authentication type you select. If you select ‘Not Use’, data will not
be encrypted and people with some networking knowledge will be able to read the data
you transfer with proper tool.
WPA Pre-shared
Key
Please input the WPA pre-shared key here. Only clients with the same pre-shared key
you inputted here will be able to connect to your computer. This setting is only
available when you select one of WPA encryptions.
Group Rekey
Interval
You can specify the time interval to re-issue the key to your wireless clients here. You
can click the button ’10 seconds’ or ‘Kpackets’ to change the unit of time interval.
(every 10 seconds or a thousand data packets times the value you specified in ‘Group
Rekey Interval’ field).
Wep Key Please input the WEP encryption key here when you select ‘WEP’ as encryption type.
There are 2 types of WEP key: Hex (number 0 to 9, and ASCII characters A to F) and
ASCII (all alphanumerical characters plus symbols). Please select the type of WEP key
first, and then input the WEP key according to the type of WEP key you selected. If you
want to use WEP 64 bits encryption, please input 10 characters if you select HEX, or
input 5 characters if you select ASCII. If you want to use WEP 128bits encryption,
please input 26 characters if you select HEX, or input 13 characters if you select ASCII.
128 bits encryption is safer then 64 bits, but the data transfer speed will be slightly
reduced.
3-3 Access Control
If you’re not going to open your computer and wireless resources to the public, you can use MAC address
filtering function to enforce your access control policy, so only wireless clients with MAC address you defined
by this function can be connected to your software access point.
