4-2 Troubleshooting 
 
If you found the router is working improperly or stop 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 cord 
and network cable of this router. All cords 
and cables should be correctly and firmly 
inserted to the router. 
b. If all LEDs on this router are out, please 
check the status of D/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 
perform a hard reset (pressing ‘reset’ 
button). 
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, sometime 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 
with your computer directly attached to the  
						

							 
124
comm. 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 
website, 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 comm. device provided by your 
Internet service provider too. 
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 installed and 
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. 
e. If antenna is not installed, install them now 
and never remove them. 
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 never happens before, call you 
Internet service provider to know if there is  
						

							 
125
something wrong with their network. 
I can’t log onto web 
management interface: 
password is wrong a. Make sure you’re connecting to the correct 
IP address of the router! 
b. Password is case-sensitive. Make sure the 
‘Caps Lock’ light is not illuminated. 
c. If you really forget the password, do a hard 
reset. 
Router become hot  a. This is not a malfunction, if you can keep 
your hand on the router’s case. 
b. If you smell something wrong or see the 
smoke coming out from router or D/C 
power adapter, please disconnect the router 
and D/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, that identifies a single, unique 
Internet computer host in an IP network. Example: 192.168.2.1. 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. 
A network mask is also a 32-bit binary pattern, and consists of consecutive leading 
1’s followed by consecutive trailing 0’s, such as 
11111111.11111111.11111111.00000000. Therefore sometimes a network mask can also be 
described simply as “x” number of leading 1’s.  
						

							 
127
When both are represented side by side in their binary forms, all bits in the IP address that 
correspond to 1’s in the network mask become part of the IP network address, and the 
remaining bits correspond to the host ID.   
 
For example, if the IP address for a device is, in its binary form, 
11011001.10110000.1001
0000.00000111, and if its network mask is, 
11111111.11111111.11110000.00000000 
It means the device’s network address is   
11011001.10110000.1001
0000.00000000, and its host ID is, 
00000000.00000000.00000000.00000111
. This is a convenient and efficient method for 
routers to route IP packets to their destination. 
ISP Gateway Address: (see ISP for definition). The ISP Gateway Address is an IP 
address for the Internet router located at the ISPs office.   
ISP: Internet Service Provider. An ISP is a business that provides connectivity to the 
Internet for individuals and other businesses or organizations.  
LAN: Local Area Network. A LAN is a group of computers and devices connected 
together in a relatively small area (such as a house or an office). Your home network is 
considered a LAN.  
MAC Address: MAC stands for Media Access Control. A MAC address is the hardware 
address of a device connected to a network. The MAC address is a unique identifier for a 
device with an Ethernet interface. It is comprised of two parts: 3 bytes of data that 
corresponds to the Manufacturer ID (unique for each manufacturer), plus 3 bytes that are 
often used as the product’s serial number. 
NAT: Network Address Translation. This process allows all of the computers on your 
home network to use one IP address. Using the broadband router’s NAT capability, you 
can access the Internet from any computer on your home network without having to 
purchase more IP addresses from your ISP.   
Port: Network Clients (LAN PC) uses port numbers to distinguish one network 
application/protocol over another. Below is a list of common applications and 
protocol/port numbers: 
Application Protocol Port Number
Telnet TCP 23  
						

							 
128
FTP TCP 21 
SMTP TCP 25 
POP3 TCP 110 
H.323 TCP 1720 
SNMP UCP 161 
SNMP Trap  UDP  162 
HTTP TCP 80 
PPTP TCP 1723 
PC Anywhere  TCP  5631 
PC Anywhere  UDP  5632 
 
 
PPPoE: Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a secure data 
transmission method originally created for dial-up connections; PPPoE is for Ethernet 
connections. PPPoE relies on two widely accepted standards, Ethernet and the 
Point-to-Point Protocol. It is a communications protocol for transmitting information over 
Ethernet between different manufacturers 
 
Protocol: A protocol is a set of rules for interaction agreed upon between multiple parties 
so that when they interface with each other based on such a protocol, the interpretation of 
their behavior is well defined and can be made objectively, without confusion or 
misunderstanding.  
 
Router: A router is an intelligent network device that forwards packets between different 
networks based on network layer address information such as IP addresses. 
Subnet Mask: A subnet mask, which may be a part of the TCP/IP information provided 
by your ISP, is a set of four numbers (e.g. 255.255.255.0) configured like an IP address. It 
is used to create IP address numbers used only within a particular network (as opposed to 
valid IP address numbers recognized by the Internet, which must be assigned by 
InterNIC).  
TCP/IP, UDP: Transmission Control Protocol/Internet Protocol (TCP/IP) and Unreliable 
Datagram Protocol (UDP). TCP/IP is the standard protocol for data transmission over the 
Internet. Both TCP and UDP are transport layer protocol. TCP performs proper error 
detection and error recovery, and thus is reliable. UDP on the other hand is not reliable.  
						

							 
129
They both run on top of the IP (Internet Protocol), a network layer protocol. 
 
WAN: Wide Area Network. A network that connects computers located in geographically 
separate areas (e.g. different buildings, cities, countries). The Internet is a wide area 
network. 
 
Web-based management Graphical User Interface (GUI): Many devices support a 
graphical user interface that is based on the web browser. This means the user can use the 
familiar Netscape or Microsoft Internet Explorer to Control/configure or monitor the 
device being managed.
