The 64-bit encryption is currently the 802.11 standard. The 128-bit 
encryption is supported by equipment from a limited number of vendors. 
Note that the “user-controlled” portion of the 64-bit encryption is just 40 
bits (10 Hex digits) and that for the 128-bit encryption is just 104 bits (26 
Hex digits)—3-bytes of the encryption key are internal to the encryption 
algorithm. 
 

 
WEP key:

  

The keys allows hex number inputs with varying length depending on the 
type of WEP being enabled i.e. 64 or128bit WEP 

 

Advanced 

On this page (Figure 7) you can configure the advanced 802.11g settings such 
as Bridging, Advance Wireless Settings, and Firmware Upgrade option.  
 

1. Bridging 

To activate the Bridging mode, the user needs to select WLAN Bridge 
option to allow multiple clients connecting to an ACR-201-G unit. If WLAN 
Client option is selected, the ACR-201-G unit can connect to only a single 
client. 

 

2. Advance Wireless  

Fragmentation threshold 

Transmitted wireless packets larger than this size will be fragmented to 
maintain performance in noisy wireless networks. In the presence of 
hostile RF environment, frames longer than this threshold number, in 
bytes, are divided prior to transmission into one or more fragments less 
than or equal in length to the fragmentation threshold. The default value is 
set at 2346 bytes. This is the maximum 802.11 data frame size, such that 
no frames are ever fragmented. The valid range of fragmentation 
threshold is 1 to 3000.
