Appendix C

Frequently Asked Questions

C.0

In the process of firmware upgrade, an error message appears on the message
window and stops the upgrading process or the upgrade process was not
completed.

To rectify this error, please

RESET

the NP16A by depressing the

RESET

button for 5

seconds. Next, log onto the configuration page using uConfig software and reinitiate the
upgrade process again.

C.1

I have forgotten the IP address that I have set on my NetPassage 16A, what should
I do?

You may run the utility NPFIND.EXE located in the Product CD, it will report the IP
address of the NetPassage 16A found in the network.

C.2

The “CONN” LED on my NetPassage 16A is flashing rapidly, and I cannot connect
to the web-based configuration interface, why?

The rapid flashing of the “CONN” LED indicates that the router firmware has been
corrupted. The firmware recovery utility may be found on the Product CD.

C.3

I have configured NetPassage 16A with my broadband Internet account. I am able
to PING the ISP gateway IP address. However, I cannot surf the Internet.

If you have not configured the DHCP server to configure the DNS information of the
computers in the network, you need to manually configure the DNS entry on every
computer. Without the DNS server, your will not be able to resolve domain name (eg

www.compex.com.sg

) into IP address. Refer to

Section 2.5 on how to configure for

DNS server on the computer

.

C.4

I am using Cable Internet and have tried to configure NetPassage 16A to work with
it. I just couldn’t get the ISP to release an IP to me. When I connected my
computer directly to the Cable modem, I am able to surf the Internet.

Your ISP has probably logged the MAC address of your computer. You should clone the
MAC address of your computer to NetPassage 16A. Refer to paragraph titled

Cloning

MAC Address to NetPassage 16A

under

Section 3.2.1

C.5

I have activated the Wireless LAN Option on NetPassage 16A. All my wireless
clients are now able to surf the Internet. However, my wireless clients cannot share
the resources with each other.

You have probably activated Wireless Pseudo VLAN on NetPassage 16A. Wireless
Pseudo VLAN strengthens the privacy by isolating the wireless clients in their
respective Pseudo VLAN. If you wish to share resources among your wireless clients,
deactivate the Wireless Pseudo VLAN.
