Frequent loss of ADSL linesync (disconnections).

Billion BIPAC-7500G–802.11g ADSL VPN Firewall Router with 3DES Accelerator

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.
