works in 11b or 11b/g mixed mode, you can choose either 

1, 2 Mbps

 or 

1, 2, 5.5, 

11Mbps

. If the AP operates in pure 11g mode, you can choose one of the four 

modes. But for better performance, the last two modes (1, 2, 5.5, 11, 6, 12, 24Mbps 

and 6, 12, 24 Mbps) are recommended.   

Ø 

SSID:

 Service Set Identifier (up to 32 printable ASCII characters). The SSID must 

be identical for all the clients and AP of the same wireless network.   

Ø 

Hide SSID: 

If this is checked, the AP will not incorporate its SSID into the field of the 

beacon frame regularly sent by the AP, which means only wireless stations set with 

the same SSID can connect to the AP. It prevents the AP from unauthorized user 

access. 

Ø 

Tx Power: 

There are four levels (Level 0-3) for you to configure the transmission 

power of the AP. The higher transmission power, the larger transmission distance 

and wireless signal coverage will be. 

Ø 

Change/Apply: 

Click 

Change

 will enable you to configure the parameters in the 

General Connection Setting

 field. Meanwhile, it will turn into 

Apply

 for you to 

confirm the modified settings. 

WEP:

 You can disable/enable the WEP encryption. To implement it, the Authentication 

type (Open system/Shared key) and the WEP key format (Hex/ASCII), length 

(64/128/256-bit) and ID(1-4) must be identical on the AP and client side. The AP supports 

64/128/256-bit Hex/ASCII WEP encryption. About detailed descriptions, please refer to 

the Section 3.3. 

Authentication Mode:

   

Ø 

Open system: 

In this mode, wireless stations directly associate with the access 

point without any authentication (null authentication). You can decide whether to 

employ WEP data encryption. 

Ø 

Shared key: 

In this mode, wireless stations communicate with the access point 

using the identical WEP key settings for user authentication and data encryption. It 

always combines with WEP data encryption. 

Fragment: 

This value defines the maximum transmitted packet size. Any packet size is 

larger than it will be fragmented. If you hit upon a high packet error rate, try to increase 

this value, but the performance will thus be affected. Keeping the default setting applies to 

most scenarios.

 

RTS/CTS: 

This feature focuses on solving the 

Hidden Note

 issue and avoiding 

subsequent collisions. If you encounter a constant high packet error rate and high latency, 

try to adjust this value to find the suitable one for your wireless network. However, its 

implementation will cause additional overhead to your wireless network.

 

Preamble: 

It defines the length of the CRC block for communication within the wireless 

network. There are two types available: Long and Short. If your wireless network consists
