Disable Wireless Client Association

. If your router is the repeater, selecting this check

box means that wireless clients cannot associate with it. Only LAN client associations are

allowed.

-

If you are setting up a point-to-point bridge, select this check box.

-

If you want all client traffic to go through the other access point (repeater with

wireless client association), leave this check box cleared.

•

Wireless MAC of this router

. This field displays the MAC address for your router for

your reference. You will need to enter this MAC address in the corresponding Wireless

Repeating Function screen of the other access point you are using.

Repeater IP Address

. If your router is the repeater, enter the IP address of the other

access point.

Base Station MAC Address

. If your router is the repeater, enter the MAC address for

the access point that is the base station.

•

Wireless Base Station

. If your router is the base station, select this check box.

Disable Wireless Client Association

. If your router is the base station, selecting this

check box means that wireless clients cannot associate with it. Only LAN client

associations are allowed.

Repeater MAC Address (1 through 4)

. If your router is the base station, it can act as the

“parent” of up to 4 other access points. Enter the MAC addresses of the other access

points in these fields.

Set Up the Base Station

The wireless repeating function works only in hub and spoke mode. The units cannot be

daisy-chained. You have to know the wireless settings for both units. You have to know the

MAC address of the remote unit. First, set up the base station, and then set up the repeater.



To set up the base station:

1.

Set up both units with exactly the same wireless settings (SSID, mode, channel, and

security). The wireless security option has to be set to None or WEP.

Select

Advanced > WiFi Repeating

to display the Wireless Repeating Function screen.

3.

In the Wireless Repeating Function screen, select the

Set Up a Repeater Unit

Use a wired Ethernet connection to set up the repeater unit to avoid conflicts with the

wireless connection to the base station.

Note:

If you are using the N150R base station with a different router as the

repeater, you might need to change additional configuration

settings. In particular, you should disable the DHCP server function

on the wireless repeater AP.



To configure the router as a repeater unit:

1.

Log in to the router that will be the repeater. Select

Setup > WiFi Settings

and

verify

that the wireless settings match the base unit exactly. The wireless security option has

to be set to

WEP

or

None

.

2.

Select

Advanced > WiFi Repeating Function

, and select the

Enable Wireless Repeating

Function

check box and the

Wireless Repeater

radio button.

3.

Fill in the Repeater IP Address field. This IP address has to be in the same subnet as the

base station, but different from the LAN IP address of the base station.

4.

Click

Apply

to save your changes.

5.

Verify connectivity across the LANs.

A computer on any wireless or wired LAN segment of the router should be able to

connect to the Internet or share files and printers with any other wireless or wired

computer or server connected to the other access point.

Dynamic DNS

If your Internet service provider (ISP) gave you a permanently assigned IP address, you can

register a domain name and have that name linked with your IP address by public Domain

Name Servers (DNS). However, if your Internet account uses a dynamically assigned IP

address, you do not know in advance what your IP address will be, and the address can

change frequently. In this case, you can use a commercial Dynamic DNS service. This type

of service lets you register your domain to their IP address and forwards traffic directed at

your domain to your frequently changing IP address.

If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the Dynamic

DNS service does not work because private addresses are not routed on the Internet.

Your router contains a client that can connect to the Dynamic DNS service provided by

DynDNS.org. First visit their website at

and obtain an account and

host name that you configure in the router. Then, whenever your ISP-assigned IP address

changes, your router automatically contacts the Dynamic DNS service provider, logs in to

your account, and registers your new IP address. If your host name is hostname, for

example, you can reach your router at

.

Select

Advanced > Dynamic DNS

to display the following screen:



To set up Dynamic DNS:

1.

Register for an account with one of the Dynamic DNS service providers whose names

appear in the Service Provider list. For example, for DynDNS.org, select

www.dyndns.org

.

2.

Select the

Use a Dynamic DNS Service

check box.

3.

Select the name of your Dynamic DNS service provider.

4.

Type the host name (or domain name) that your Dynamic DNS service provider gave you.

5.

Type the user name for your Dynamic DNS account. This is the name that you use to log in

to your account, not your host name.

6.

Type the password (or key) for your Dynamic DNS account.

7.

If your Dynamic DNS provider allows the use of wildcards in resolving your URL, you can

select the

Use Wildcards

check box to activate this feature.

For example, the wildcard feature causes *.yourhost.dyndns.org to be aliased to the

same IP address as yourhost.dyndns.org.

Static Routes

Static routes provide additional routing information to your router. Typically, you do not need

to add static routes. You have to configure static routes only for unusual cases such as

multiple routers or multiple IP subnets on your network.

As an example of when a static route is needed, consider the following case:

•

Your primary Internet access is through a cable modem to an ISP.

•

You have an ISDN router on your home network for connecting to the company where

you are employed. This router’s address on your LAN is 192.168.1.100.

•

Your company’s network address is 134.177.0.0.

When you first configured your router, two implicit static routes were created. A default route

was created with your ISP as the gateway, and a second static route was created to your

local network for all 192.168.1.x addresses. With this configuration, if you attempt to access

a device on the 134.177.0.0 network, your router forwards your request to the ISP. The ISP

forwards your request to the company where you are employed, and the request is likely to

be denied by the company’s firewall.

In this case you have to define a static route, telling your router that 134.177.0.0 should be

accessed through the ISDN router at 192.168.1.100. In this example:

•

The Destination IP Address and IP Subnet Mask fields specify that this static route

applies to all 134.177.x.x addresses.

•

The Gateway IP Address field specifies that all traffic for these addresses should be

forwarded to the ISDN router at 192.168.1.100.

•

A metric value of 1 will work since the ISDN router is on the LAN.

•

Private is selected only as a precautionary security measure in case RIP is activated.



To set up a static route:

1.

Select

Advanced > Static Routes

, and click

Add

to display the following screen:

2.

In the Route Name field, type a name for this static route (for identification purposes only.)

3.

Select the

Private

check box if you want to limit access to the LAN only. If Private is

selected, the static route is not reported in RIP.

4.

Select the

Active

check box to make this route effective.

5.

Type the destination IP address of the final destination.

6.

Type the IP subnet mask for this destination. If the destination is a single host, type

255.255.255.255

.

7.

Type the gateway IP address, which has to be a router on the same LAN segment as the

N150R router.

8.

Type a number from 1 through 15 as the metric value.

This value represents the number of routers between your network and the destination.

Usually, a setting of 2 or 3 works, but if this is a direct connection, set it to 1.

9.

Click

Apply

to add the static route.

Remote Management

The remote management feature lets you upgrade or check the status of your N150R router

over the Internet.



To set up remote management:

1.

Select

Advanced > Remote Management

.

Note:

Be sure to change the router’s default login password to a secure

password. The ideal password contains no dictionary words from any

language and contains upper-case and lower-case letters, numbers, and

symbols. It can be up to 30 characters.

2.

Select the

Turn Remote Management On

check box.

3.

Under Allow Remote Access By, specify the external IP addresses to be allowed to access

the router’s remote management.
