Troubleshooting
If you cannot connect to SHDSL network, please check the status of the LEDs on the front
panel, and then ensure the following:
1. Check the LAN LED
If the LAN LED goes off, ensure that the Ethernet cable is firmly connected both to the
LAN port on the Corecess 3311 and Ethernet port on your PC.
2. Check the LINK LED
If the LINK LED blinks continuously and never stays solid on, ensure that the SHDSL
cable is firmly connected to the LINE port on the Corecess 3311. If the LINK LED still
blinks, contact your SHDSL service provider.
If the LINK LED goes off, turn off the power of the Corecess 3311 by pressing the power
switch and turn on the power again. If LINK LED still goes off, contact your vendor.
3. Check your PC’s IP address
If all LEDs operate normally and cables are firmly connected to the ports, ensure that
your PC’s IP address is properly assigned. Otherwise assign a new IP address according
to your operating system.
