- Setting up the ZyAIR router

The following procedure is for the most typical usage of the ZyAIR where you have a single-user account (SUA). The ZyAIR supports embedded web server that allows you to use Web browser to configure it. Before configuring the router using Browser please be sure there is no Telnet or Console login.

1. Retrieve ZyAIR Web

Please enter the LAN IP address of the ZyAIR router in the URL location to retrieve the web screen from the ZyAIR. The default LAN IP of the ZyAIR is 192.168.1.1. See the example below.

2. Login first

To restrict only the adminstrator can configure the router, there is a login procedure prompted for asking User Name and Password. The default User Name is 'admin' and the default password is the default SMT password, '1234'.

3. Configure ZyAIR for Internet access by using WIZARD SETUP. The Web screen shown below takes PPPoE as the example.

Key Settings:

Option | Description
Encapsulation | Select the encapsulation type your ISP supports
Service Name | Enter the 'Service Name' for the ISP
User Name | Enter the login user name given by the ISP
Password | Enter the password given by the ISP
Idle Timeout | This value specifies the time in seconds that can elapse before the ZyAIR automatically disconnects the PPPoE connection.
IP Address Assignment | Choose 'Dynamic' if the ISP provides the IP dynamically, otherwise choose 'Static' and enter the static IP in the 'IP Address' field.
Network Address Translation | Set this field to 'SUA Only' if you want all clients share one IP to Internet. Set to 'Full Feature' if there are multiple IP addresses given by ISP and can assigned to your clients. Set to 'None' if you clients use Internet IP addresses and thus do not need NAT function.

4. WAN IP Address Assignment

Check 'Get automatically from ISP' if the ISP provides the IP dynamically, otherwise check 'Use fixed IP address' and enter the static IP in the 'IP Address' field.

5. Check if the connection is up by clicking the ADVANCED/MAINTENANCE menu.
