When you finish with setting and want to save changes, click ‘OK’ button, or click ‘Cancel’ button to discard
all changes you made.
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.
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.
