Apple AirPort Networks Guía para resolver problemas descargar pdf (Pagina 46)

for a computer on the network—which forces that computer to

reconnect—the cracker can grab the network’s name. So you cannot

rely on closing your network for any real security.

Although I discourage bothering with a closed network, here’s how

to set one up:

1. In AirPort Utility (Mac or iOS), select and edit your base station,

and then:

‣ On a Mac: Click the Wireless button and then the

Wireless

Options button; then select the Create Hidden Network

checkbox.

‣ In iOS: Tap Network, and then turn on the Hidden Network

switch.

2. Update

the base station:

‣ On a Mac: Click Save and then click Update.

‣ In iOS: Tap Done repeatedly to reverse

through a few

configuration screens and then tap Update.

3. Wait for the base station to reboot.

Timed Access Control

Apple used to offer a way to limit access to devices by their MAC

address, a unique identifier set for every network adapter. While

this feature was removed, AirPort Utility does retain Timed Access

Control (in the Network view) to limit devices to access the network

on specific days of the week during specific hour ranges. You set

access for a device by its MAC address (see

Appendix D: What and

Where Is a MAC Address?).

The feature can be useful if you’re trying to keep your kids (or

spouse?) from using the

Internet except during certain hours, but

I find that it is too fussy to recommend, and the same settings must

be re-entered on every base station on a network. It also doesn’t

restrict plugging in via Ethernet.
