2 System Requirements
Adelphia strongly recommends users that are looking to purchase and/or use their own modem get a DOCSIS 2.0 compatible model from the current recommend modem list.
Adelphia's official recommended modem list can be found here:
It has been found that not all modems, even newer DOCSIS 2.0 modems such as the Motorola SB5120, will currently support Adelphia's Extreme tier's (16000/2000) bandwidth.
An Extreme approved list is also available and can currently be found on this notice:
• Windows NT SP5
• Windows 98 First Edition
• Windows 98 Second Edition (98SE)
• Windows Millennium Edition (ME)
• Windows 2000
• Windows XP
For Apple Macintosh based computers:
• Mac OS 8.1 through Mac OS X 10
However, Adelphia does not offer any tech support for systems not running Windows 98 and above or Macintosh 8.1 and above.
