3.2 Internet Connection Wizard  
The Wizard Setup screens appear by default after login only the first time you access the ZyAIR and  
run the wizard. After that, the SYSTEM QUICK VIEW screen appears after login.  
1. The first Wizard screen displays after your initial login. This first screen varies depending on the  
type of Internet connection you use.  
Select DHCP Client if your ISP did not assign  
you a fixed IP address. Your ISP assigns the  
ZyAIR’s WAN port a dynamic IP address. This is  
the default selection.  
Click Next to continue to Figure 9.

ZyAIR G-4100  
Select Static IP Setting If the ISP assigned a  
fixed IP address.  
Enter the WAN IP address, subnet mask,  
gateway IP address and DNS server address(s)  
that your ISP assigned you.  
Click Next to continue to Figure 9.  
Figure 6 Internet Connection: Static IP  
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.  
Figure 7 Internet Connection: PPPoE  
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.

have a static IP address (My IP Address) in this  
case. Your ISP may also provide a subnet mask  
(My Subnet Mask) and a gateway IP address  
(Gateway IP address).  
Enter the DSL terminator IP address (PPTP  
Server IP Address) and the username and  
associated password exactly as your ISP  
assigned them.
