What has changed on my system?
87% of people inadvertently change settings on their system that cause 
connection problems.  This may be due to installing new software that changes 
your settings of which you are unaware (such as AOL).  Software and modem 
updates can also cause connection problems if not installed or configured correctly. 
Accidental keystrokes or accidentally leaving the caps lock key engaged on your 
computer can also cause problems.

What other things should I check?
  • Try redialing to Internet Channel on your ISDN line.
  • Try restarting your computer as well as repowering your ISDN modem or router.
  • Check to make sure all connections, including cables, are securely seated and installed between your modem/router, computer, and ISDN jack.
  • If you are running a Windows 95 machine, check to make sure "Enable Software Compression" is not checked.
  • Ascend Pipeline users, make sure you have the default gateway set to 10.254.254.1
