Frequently Asked Questions
Which cable do I use to connect a new LAN device to the router?
If you are connecting your LAN device to one of the Ethernet ports on your
router, use a straight-through (red) cable.
If you are connecting your router directly to another hub, then use a crossover
(yellow) cable. If your hub has a built-in crossover or uplink port, then you must
use a straight-through (red) cable.
Can I connect the router to a 100Base-T hub?
Yes, if the hub has a 10/100 switch. You need to set the switch to 10 for the
router connection.
What is the router password?
The default user name is login and the password is admin.
We strongly recommend that you change the router password from the default to
your own password. If your NSP has changed the router password from the
default, you’ll need to contact them for assistance.
What security options do I have?
Network Address Translation (NAT) is a feature that can provide a level of
security by hiding the private IP addresses of your LAN behind the single public
IP address of your router. All connections must come through your router and be
translated by NAT.
Further security is available with IP filtering firewall software. The firewall can
be accessed through the Web GUI or Command Line Interface (CLI) and
configured with scripts for a “quick” firewall. A qualified technician should
perform all firewall configuration. Efficient Networks cannot be liable for
vulnerabilities arising from inadequate firewall configurations.
