Billion Electric Company 7300M User Manual

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. If you have a back-to-base alarm system you 

should contact your security provider for a technician to make 

any necessary changes. 

 

Problems with the LAN Interface 

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.
