Chapter 5: Troubleshooting 
 
Frequent loss of 
ADSL linesync 
(disconnections). 
Ensure that all other devices connected to the same telephone line as your 
Billion router (e.g. telephones, fax machines, analogue modems) have a 
line filter connected between them and the wall socket (unless you are 
using a Central Splitter or Central Filter installed by a qualified and 
licensed electrician), and ensure that all line filters are correctly installed 
and the right way around. Missing line filters or line filters installed the 
wrong way around can cause problems with your ADSL connection, 
including causing frequent disconnections. 
 
Problems with the LAN Interface 
Problem 
Corrective Action 
Can’t ping any PCs on 
the LAN. 
Check the Ethernet LEDs on the front panel. The LED should be on for a 
port that has a PC connected. If it is off, check the cables between your 
router and the PC. Make sure you have uninstalled any software firewall 
for troubleshooting. 
 
Verify that the IP address and the subnet mask are consistent between the 
router and the workstations.
