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. 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
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.
