You can completely turn off the wireless portion of the wireless router. For example, if you

use your notebook computer to wirelessly connect to your wireless router, and you take a

business trip, you can turn off the wireless portion of the wireless router while you are

traveling. Other members of your household who use computers connected to the wireless

router via Ethernet cables can still use the wireless router. To do this, clear the

Enable

Wireless Access Point

check box on the Advanced Wireless Settings screen, and then click

Apply

•

Enable SSID Broadcast

for wireless testing and advanced configuration only. Do not change these settings.

Protecting Access to Your WNR3500v2 Router

For security reasons, the wireless router has its own user name and password. Also, after a period

of inactivity for a set length of time, the administrator login automatically disconnects. When

prompted, enter

admin

for the wireless router user name and

password

for the wireless router

password. You can use procedures in the following sections to change the wireless router

password and the amount of time for the administrator’s login time-out.

NETGEAR recommends that you change this password to a more secure password. The ideal

password should contain no dictionary words from any language, and should be a mixture of both

upper and lower case letters, numbers, and symbols. Your password can be up to 30 characters.

Note:

The user name and password are not the same as a user name or password you

might use to log in to your Internet connection.

Restricting Access by MAC Address

For increased security, you can restrict access to the wireless network to allow only specific PCs

based on their MAC addresses. You can restrict access to only trusted PCs so that unknown PCs

cannot wirelessly connect to the WNR3500v2 router. MAC address filtering adds an obstacle

against unwanted access to your network, but the data broadcast over the wireless link is fully

exposed.

To restrict access based on MAC addresses:

1.

Log in to the wireless router at its default LAN address of

with

its default user name of

admin

, and default password of

password

, or using whatever user

name, password, and LAN address you have chosen for the wireless router.

From Advanced section of the main menu, select Wireless Settings, and then click

Setup

Access List

to display the Wireless Station Access List screen.

3.

Click

Add

to add a wireless device to the wireless access control list. The Wireless Card

Access Setup screen opens and displays a list of currently active wireless cards and their

Ethernet MAC addresses.

Note:

If you configure the router from a wireless computer, add your computer’s

MAC address to the access list. Otherwise you will lose your wireless

connection when you click Apply. You must then access the wireless router

from a wired computer, or from a wireless computer that is on the access

control list, to make any further changes.
