4-2 Troubleshooting
If you found the router is working improperly or stops responding to you,
don’t panic! Before you contact your dealer of purchase for help, please
read this troubleshooting first. Some problems can be solved by yourself
within very short time!
Scenario
Solution
Router is not
responding to me
when I want to access
it by web browser
a.
Please check the connection of power cords
and network cables of this router. All cords
and cables should be correctly and firmly
inserted into the router.
b.
If all LEDs on this router are off, please
check the status of A/C power adapter, and
make sure it’s correctly powered.
c.
You must use the same IP address section
which router uses.
d.
Are you using MAC or IP address filter?
Try to connect the router by another
computer and see if it works; if not, please
restore your router to factory default
settings (pressing ‘reset’ button for over 10
seconds).
e.
Set your computer to obtain an IP address
automatically (DHCP), and see if your
computer can get an IP address.
f.
If you did a firmware upgrade and this
happens, contact your dealer of purchase for
help.
g.
If all above solutions don’t work, contact
the dealer of purchase for help.
Can’t get connected to
Internet
a.
Go to ‘Status’ -> ‘Internet Connection’
menu, and check Internet connection status.
b.
Please be patient, sometimes Internet is just
that slow.
c.
If you connect a computer to Internet
directly before, try to do that again, and
check if you can get connected to Internet
Page 133 / 138
124
with your computer directly attached to the
device provided by your Internet service
provider.
d.
Check PPPoE / L2TP / PPTP user ID and
password again.
e.
Call your Internet service provide and check
if there’s something wrong with their
service.
f.
If you just can’t connect to one or more
websites, but you can still use other internet
services, please check URL/Keyword filter.
g.
Try to reset the router and try again later.
h.
Reset the device (modem) provided by your
Internet service provider.
i.
Try to use IP address instead of hostname. If
you can use IP address to communicate with
a remote server, but can’t use hostname,
please check DNS setting.
I can’t locate my
router by my wireless
client
a. ‘Broadcast ESSID’ set to off?
b. All three antennas are properly secured.
c. Are you too far from your router? Try to get
closer.
d. Please remember that you have to input
ESSID on your wireless client manually, if
ESSID broadcast is disabled.
File download is very
slow or breaks
frequently
a.
Are you using QoS function? Try to disable
it and try again.
b.
Internet is slow sometimes, be patient.
c.
Try to reset the router and see if it’s better
after that.
d.
Try to know what computers do on your
local network. If someone’s transferring big
files, other people will think Internet is
really slow.
e.
If this has never happened before, call your
Internet service provider to know if there is
something wrong with their network.
I can’t log onto web
a. Make sure you’re connecting to the correct
Page 134 / 138
125
management interface:
password is wrong
IP address of the router!
b. Password is case-sensitive. Make sure the
‘Caps Lock’ light is not illuminated.
c. If you really forgot the password, do a hard
reset.
Router becomes hot
a.
This is not a malfunction, as long as it is not
so hot that you cannot touch it for a
prolonged period of time
b.
If you smell something wrong or see smoke
coming out from router or A/C power
adapter, please disconnect the router and
A/C power adapter from utility power
(make sure it’s safe before you’re doing
this!), and call your dealer of purchase for
help.
The date and time of
all event logs are
wrong
a. Adjust the internal clock of router.

4-3 Glossary
Default Gateway (Router):
Every non-router IP device needs to configure a default
gateway’s IP address. When the device sends out an IP packet, if the destination is not
on the same network, the device has to send the packet to its default gateway, which
will then send it out towards the destination.
DHCP:
Dynamic Host Configuration Protocol. This protocol automatically gives
every computer on your home network an IP address.
DNS Server IP Address:
DNS stands for Domain Name System, which allows
Internet servers to have a domain name (such as www.Broadbandrouter.com) and one
or more IP addresses (such as 192.34.45.8). A DNS server keeps a database of
Internet servers and their respective domain names and IP addresses, so that when a
domain name is requested (as in typing "Broadbandrouter.com" into your Internet
browser), the user is sent to the proper IP address. The DNS server IP address used by
the computers on your home network is the location of the DNS server your ISP has
assigned to you.
DSL Modem:
DSL stands for Digital Subscriber Line. A DSL modem uses your
existing phone lines to transmit data at high speeds.
Ethernet:
A standard for computer networks. Ethernet networks are connected by
special cables and hubs, and move data around at up to 10/100 million bits per second
(Mbps).
Idle Timeout:
Idle Timeout is designed so that after there is no traffic to the Internet
for a pre-configured amount of time, the connection will automatically be
disconnected.
IP Address and Network (Subnet) Mask:
IP stands for Internet Protocol. An IP
address consists of a series of four numbers separated by periods, which identifies a
single, unique Internet computer host in an IP network. Example: 192.168.1.2. It
consists of 2 portions: the IP network address, and the host identifier.
The IP address is a 32-bit binary pattern, which can be represented as four cascaded
decimal numbers separated by “.”: aaa.aaa.aaa.aaa, where each “aaa” can be anything
from 000 to 255, or as four cascaded binary numbers separated by “.”:
bbbbbbbb.bbbbbbbb.bbbbbbbb.bbbbbbbb, where each “b” can either be 0 or 1.
