Figure 7 Internet Connection: PPPoE 

Select 

PPPoE

 If the ISP uses PPPoE for your 

account (PPPoE simulates a dial-up connection). 

Enter the user name and password 

exactly

 as 

your ISP assigned them. 

A maximum transmission unit (MTU) is the 
largest size packet or frame, specified in octets 
(eight-bit bytes) that can be sent in a packet- or 
frame-based network. The Transmission Control 
Protocol (TCP) uses the MTU to determine the 
maximum size of each packet in a transmission. 
Too large an MTU size may mean 
retransmissions if the packet encounters a router 
that can't handle that large a packet. Too small 
an MTU size means relatively more header 
overhead and more acknowledgements that 
have to be sent and handled.  

The maximum segment size (MSS) is the largest 
amount of data, specified in bytes, that a 
computer or communications device can handle 
in a single, unfragmented piece. 

For optimum communications, the number of bytes in the data segment and the header must add up to less than 
the number of bytes in the maximum transmission unit (MTU). 

Enter the name of your PPPoE server, in the 

Service Name 

field if provided; otherwise leave it blank. 

Select 

Connect on Demand

 when you don't want an “always-on” connection and specify an inactivity time limit 

(in minutes) in the 

Max Idle Time 

field.
