Specification 

IP Address 

  Default IP address 192.168.1.2 

Submask  

Make calculation for source IP 
address and submask, and 
destination IP address and submask 

respectively. If identical result can be 
got, the source and destination are in 
the same subnet. Otherwise, they are 
in different subnet and the 
connection should go through 

gateway.  
Default :255.255.255.0 

Network

Gateway IP 

Address 

 

If the source and destination are in 
different subnet, gateway IP address 
should be set. 
Default:192.168.1.1

The bigger the packet is ,the more 

data is encapsulated in each packet, 
and the lower overhead it has. 
Bandwidth efficiency will be raised 
and delay will be increased.

Default 0x 00 

Uplink 

Bandwidth 

 

Set full duplex bandwidth for uplink 

Ethernet port

actual bandwidth 

should be higher than this value.  

Default 10000Kbps
