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.

Figure 7 Internet Connection: PPPoE

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.

ZyAIR G-4100

Select Keep Alive if you want an “always-on” connection. The Redial Period is how long the ZyAIR waits before reconnecting in the event of a disconnect. Click Next to continue to Figure 9 .

Select PPTP if your service provider uses a DSL terminator with PPTP login. The ZyAIR must 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.
