Mac OS X: Back to My Mac requires AirPort base station or UPnP-capable third-party router

Tue, 15 Nov 2011 15:41:27 GMT+00:00

The Back to My Mac feature of Mac OS X is designed to work seamlessly with compatible AirPort base stations. This seamless integration is achieved through the use of NAT-PMP (NAT Port mapping Protocol) technology, which enables your computer to automatically configure your AirPort base station to provide services between your local network and the Internet. Some third-party Internet routers use a technology called UPnP (Universal Plug and Play), which is similar to NAT-PMP. Back to My Mac works with both NAT-PMP and UPnP.

What is IPv6?

Tue, 07 Jun 2011 17:01:28 GMT+00:00

IPv6 is short for "Internet Protocol Version 6". IPv6 is the Internet's next-generation protocol, designed to replace the current Internet Protocol, IP Version 4. In order to communicate over the Internet, computers and other devices must have sender and receiver addresses. These numeric addresses are known as Internet Protocol addresses. As the Internet and the number of people using it grows exponentially, so does the need for IP addresses.

Apple products that require an Ethernet crossover cable

Wed, 22 Oct 2008 14:27:11 GMT+00:00

This document outlines which Apple products require an Ethernet crossover cable, and which can use a standard Ethernet cable when connecting directly to another Apple product. You can connect two computers together using an Ethernet cable to form a small network. Depending on the computer model, you may need to use a crossover Ethernet cable instead of a straight-through Ethernet cable. Many later Macintosh computers are able to use either a straight-through Ethernet cable or a crossover Ethernet cable automatically through the use of Auto-Medium Dependent Interface Crossover (Auto-MDIX). Earlier Macintosh computers require the use of an Ethernet crossover cable because they only work with the Medium Dependent Interface (MDI) . Auto-MDIX automatically switches between MDI and MDI-X, which allows either type of cable to be connected regardless of whether you are connecting two computers directly, or you are connecting to a hub or switch. MDI devices connected to Auto-MDIX devices do not require a crossover Ethernet cable.

Mac OS X, AirPort: Compatible third-party wireless cards

Tue, 05 Aug 2008 19:12:16 GMT+00:00

This document describes how different types of third-party wireless PC cards may be used with Mac OS X. Wireless cards for use in an AirPort environment may be either 802.11b or 802.11g. You should choose a card appropriate for the version of Mac OS X that you are using. If your computer has an AirPort or AirPort Extreme card slot, you should consider using the corresponding Apple card for the most seamlessly integrated experience. However, a third-party PC card may be useful in situations like these: You have installed Mac OS X on an earlier PowerBook that does not have an AirPort card slot. You have a more recent PowerBook, such as the PowerBook G4 (Gigabit Ethernet), with an original AirPort Card slot. You may want to upgrade to 802.11g in this situation. Because an AirPort Extreme Card cannot be used in AirPort Card slot, a third-party PC card is an upgrade option. Note: Only the corresponding Apple-branded card may be used in an AirPort or AirPort Extreme card slot. Third-party cards discussed here may only be used in the PCMCIA (or "PC") slot on the PowerBook.

AirPort: Can Connect to Base Station But Not to Internet When Using PPPoE

Fri, 25 Jul 2008 18:58:45 GMT+00:00

Your computer may connect to the base station but not to the Internet or local network when using a PPPoE DSL or cable modem service. Your computer connects to the base station with a strong signal, but it cannot connect to the Internet or your local network. The Network preference pane may show an IP address of 10.64.64.64 for the Built-in Ethernet port. This typically occurs after adding an AirPort Base Station or third-party wireless access point where wired Ethernet was previously used to connect to a PPPoE DSL or cable modem service. In this scenario, the base station should be the only device connecting via PPPoE to the modem. The wireless connection from client to base station is not PPPoE. When you see these symptoms, the client computer is continuing its attempt to connect over the Built-in Ethernet port via PPPoE, despite the fact that no Ethernet cable is connected.
