The maximum supported rate of the Network Adapter is 100Mbit/s, at full duplex. From the SCPH-75000 series onwards, Ethernet functionality was integrated into the I/O processor (which was completely redesigned internally), completely removing the disk interface.

The first slimline model (SCPH-70000) has a complete Network Adapter onboard, and may be modified to add an external IDE connector board. Slimline PlayStation 2 models have an Ethernet port built-in (with some early North American models including an analog dial-up modem), but no official hard disk drive interface. As the two disk connectors are on separate circuit boards from the main Network Adaptor one, third party connector replacements including a SATA connector and SATA to IDE converter are available. The Network Adaptor also provides a Parallel ATA interface and a Molex disk drive power connector to allow installation of a 3.5" IDE hard disk drive in the expansion bay. Tony Hawk's Pro Skater 3, released in November 2001, supported the Network Adapter hardware, but not the software as it was not finalized until much later. A start-up disc ("Network Access Disc") is included with the Network Adaptor and installs a file on the memory card for connection settings which are accessible by all but one Network Adaptor compatible game. Two models of the adaptor were available - one with a dial-up modem and an Ethernet jack for broadband Internet connection (mainly sold in North America), and one with only an Ethernet interface (sold in Europe and other regions). The Network Adaptor was released together with the launch of the PlayStation 2’s online play service. A PS2 Network Adaptor shown by itself (top) and inserted to a console (bottom)
