(RADUIS) or Personal (Pre-Shared Key).
To configure WEP settings, select follow the steps below.
Step 1.
Select “WPA (TKIP), WPA (AES), WPA2 (TKIP), WPA2 (AES) or WPA2 (Mixed)” encryption

client’s access to the wireless ne
twork by MAC address.
Figure 4-19
Wireless Access Control Mode:
Options are “Disable”, “Allow Listed” and “Deny Listed”. If the
mode is “Disable”, it means the wireless access control function is closed;
if the mode is “Allow
Listed”, only the client on the list will be able to connect to you access point; if the mode is

screen (shown in Figure 4-20). You can configure the advanced parameters for your WLAN.
Figure 4-20
Fragment Threshold:
This value specifies the maximum size for a packet before data is
fragmented into multiple packets. If you experience a high packet error rate, you may slightly
increase the Fragmentation Threshold. Setting the Fragmentation Threshold too low may result
in poor network performance. Only minor reduction of the default value is recommended. In
most cases, it should remain at its default value of 2346.
RTS Threshold:
Should you encounter inconsistent data flow, only minor reduction of the
default value 2347 is recommended. If a network packet is smaller than the preset RTS
threshold size, the RTS/CTS mechanism will not be enabled. The Router sends Request to
Send (RTS) frames to a particular receiving station and negotiates the sending of a data frame.
After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to
acknowledge the right to begin transmission. In most cases, keep its default value of 2347.
