Problem Troubleshooting
PC unable to access
the network
Use the Ping command to check if the network interface IP
address (preset to 192.168.1.1) of the device can be pinged
from the computer. If not, check the Ethernet cable
connection. Check if the indicator status is normal.
If the computer uses a private IP address (not a registered
illegal IP) specified manually, please check:
If the computerās gateway IP address is an illegal address.
If not, use a correct gateway, or set the computer to obtain
IP information automatically.
Contact your ADSL Service Provider to confirm the DNS
server designated for the computer is valid. Otherwise, use
the correct DNS, or set the computer to obtain IP
information automatically.
Make sure you have set the NAT rule to convert the private
IP address into the legal address. The computer IP address
you specified must be contained in the range set in the
NAT rule.
A problem may occur in the office-end device of the ADSL
Service Provider.

Make sure the DNS server designated for the computer is
