you are recommended to choose “All”.

Filter Action: Allow: Allow the configured IP to pass the Router and others are

denied.

Deny: Deny the configured IP to pass the Router and others are

allowed.

Source IP Range: The IP address of the computer which

initiates a service connection. If it is null, it means to control all

the computers which initiate the service connection. You can

enter an IP address range here. For example, Start

(61.145.238.6) - End (61.145.238.47).

Destination IP Range: The IP addresses of the computers

which accept the service connection passively. If it is null, it

means to control all the computers which accept service

connection passively. You can enter an IP address range here,

82

54M Wireless ADSL2+ Modem Routerfor example, Start (192.168.1.123)-End (192.168.1.185).

Source Port Range: The service port of the computer

controlled in LAN like website server. If it is null, it means to

control all the service ports. You can enter a port range here

such as Start (25)-End (110).

Destination Port Range: The service port of the computer

controlled in LAN. If it is null, it means to control all the service

ports of the computer. You can enter a port range here such as

Start (1030)-End (2000).

Status: Displays the enable/ disable status of this rule.


For example: If you don’t want the internal computers at the IP

address of 192.168.1.8-192.168.1.20 to download by BT,

BT to download, you need to send a request to the “seed”

server. When the request passes through the Router, the

Router can filter it to prevent BT connection.

2. The ports used by “seed” server often congest between

6900 and 8100 such as 6969, 8000 and 7373. We can use

this rule to forbid the ports at this range. But some other

seed servers except BT are using 8080 port, so we often

84


divide them into two ranges：6900-8079 and 8081-8100.

3. Because it is the internal PC which initiates the BT

connection to connect the external Internet server, the data

message filter is Outbound.

4. The protocols which BT used are TCP/UDP, so forbid the

two protocols.

11.3 MAC Filter

Click “Security Setting→MAC Filter” on the left menu. As the

3. FAQ

1. Q: How to judge ADSL connection is OK?A: After the hardware is connected well, when the

connection is OK, the “ADSL-LINK” indicator of W548D will

be always on; otherwise, it will be blinking. Blinking

indicates the connection is troubled or wrong. Please

inquire your ISP or connect your cables again.

2. Q: I’m an ADSL user, but why sometimes I can’t access

the Internet?A: Because ADSL adds high frequency digital signal to the

low frequency audio of common telephone line, any device

added in the connection between the telephone company

and the ADSL filter will jeopardize the normal data

transmission. We recommend you avoid connecting

telephone or other devices before filter.

3. Q: If my place is far from the telecommunication office,

can I install ADSL?A: At present, ADSL2+ technology controls the distance

under 6.5KM. Because ADSL2+ has high requirements for

the line, it is better to keep the distance under 3KM for good

quality.

121

54M Wireless ADSL2+ Modem Router4. Q: Will ADSL be disconnected like 56K Modem?

A: Regardless whichever device is, it might be troubled at

times. ADSL line is also disconnected sometimes, but this

good quality line can reduces the chance to be

disconnected.

5. Q: I opened ADSL service, but can I use ADSL2+

Modem?A: Absolutely, ADSL2+ can comply with all the ADSL

services. When your ISP offers you ADSL2+ service, you

avoid buying another modem. In addition, the price of

ADSL2+ is almost the same as ADSL, so ADSL2+ is a

reasonable choice.

6. Q: What are VPI, VCI?

A：VPI (Virtual Path Identifier) and VCI (Virtual Channel

Identifier) are to identify ATM terminal (ADSL) for DSLAM,

usually provided the local ISP.

7. Q: What related parameters are required from your

ISP?A: For dial user, Connection protocol, User name,

Password, Value of VPI/VCI, Encapsulation mode and so

on.

8. Q: The firmware upgrade fails and why can’t I enter

122

54M Wireless ADSL2+ Modem Routerthe Web-based management interface?

A: Contact the technical engineer for support or after-sales

service engineer.

Notice:

Please download the upgrade packets from the Tenda

website.

9. Q: How to restore my device to factory default value?A: There is a reset button on the Router. Follow the steps

below to restore the device:

1) Keep the device in running status.

2) Keep pressing the reset button for about 5 seconds with

a tip object. When you release the button, the reset is

finished.

10. Q: How to obtain a correct DNS server address?A: 1) Inquiry your ISP to obtain DNS parameters;

2) After the Router successfully logins to the Web-based

management interface, select “Running Status” on the

menu and you can check the DNS parameters and

record.

11. Q: Which factors affect the wireless signals?A: 1) The walls in the house are main obstacles. Because

123

54M Wireless ADSL2+ Modem Routerwireless LAN adopts wireless microwave frequency range,

the signals received by wireless receiving devices behind

the obstacles will be rather weak.

2) Physical obstacles not only hold up the wireless signals

but also absorb the electromagnetic power.

3) The working frequency range of IEEE802.11b/g

standard is 2.4GHz, but other electrical devices are also

working in this frequency such as microwave oven,

Bluetooth device, wireless telephone and refrigerator etc.

If there are strong magnetic fields beside, wireless

network will be affected.

4) If there are multiple wireless devices in wireless

environment, channel conflict and wireless signal

interference may occur.

5) The strong signal interference resources such as

wireless transmission tower, electric welding machine,

electric car or electric transformer may disturb the wireless

signals or devices.

6) The weather may affect the outdoor wireless signals

greatly. The signals attenuate sharply in lightning storm or

gloomy weather. However, the signals in sunny weather

can transmit farther.

124

54M Wireless ADSL2+ Modem Router12. Q: How to improve signal transmitting quality?

A: 1) Choose a proper place for wireless Router. The

requirements are as follows:

1. The place should be high enough for the Router to

transmit the signals widely, thus the obstacles and dead

spots will be greatly reduced.

2. When you choose the place to set the Router, make

sure that the signals pass through fewer walls.

2) Modify channels to reduce wireless disturbance.

Notice: When you set your wireless transmitting

channel, keep above 5 channels far away from other

wireless signal channels.

3) Keep the wireless Router far away from household

appliances to reduce the disturbance of the signals.

4) If the antenna of wireless Router is detachable, you can

change it for a higher gain one to enhance wireless

signals.
