Billion BIPAC-7402 / 7402W (Wireless) ADSL VPN Firewall Router with 3DES Accelerator
Chapter 5: Troubleshooting
Frequent loss of
ADSL linesync
(disconnections).
Ensure that all other devices connected to the same telephone line as your
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.
