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.

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.

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 any 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.
