1. ADSL modem T07A (T07AW) software settings articles:

[PC] crack T07A (T07AW) ADSL modem (ADSL MODEM) setup (including setting the network card IP)

My next one will be mentioned
How to help Chunghwa Telecom ADSL modem Alcatel T07A (T07AW) the installation of cooling heat sink,

Heat is the long-term, your ADSL MODEM peacetime line no matter how no matter how fast and when a dead heat is to lie on it,
Therefore, the usefulness of this model, the summer is drawing near, the recall to retrofit its own heat sink and a small fan blowing!

The simple talk about how we go in (not break you!) ADSL modem inside the internal configuration ...
(Want to go to see the internal settings, but also must first learn how to set your own computer's network card IP)

Look at this to enter the ADSL modem or other types of internal settings,
Methods are more or less the same, nothing special. So, I explained all together.
As for the models may have some minor differences,
Because I was not a model of each have tried, in this can not be discussed separately studied 11 ...

Alcatel Alcatel T07A (wireless antennas: T07AW)
Tecom Tecom AR4031B
Alcatel Alcatel SpeedTouch 340
Comtrend CT511-C

(1) set the network card IP

ADSL modem into the internal setting, there is a need to work
That is, have to help their own network card set the IP,
ADSL modem so you will feel the network card and it is a group of,
Will allow you to enter the internal setup screen!

Even before that,
You have to first understand its own IP network card to connect a network of regional distribution system automatically?
IP is already a default, or did not set off?

If you do not need the Internet through a dial-up to this action,
Play as long as the Internet line, naturally in connection state,
Well, this is a front-end IP sharing device has an automatic will be allocated to the internal IP,
(General DHCP dispensing rules 192.168.1.2 ~ 192.168.1.255 will probably take the top 50 groups or 100 groups)
Unless you understand the scope of the allotment rules and not to the host computer and other IP settings into the same IP to each other,
Otherwise, please do not arbitrarily change their own network card IP!

If you are not computer and other computers for regional connections,
To get through a dial-up Internet access is also this move,
Then your computer should be no special network card to set the IP;
At this time, you can own their own computer to help configure a network card IP,
In this way, when boot faster, the computer no longer look for your network card IP,
Turning now to set their own IP network cards right way!

First of all, to enter the [Control Panel] --> [console connection ]
And then in the [Local Area Connection] Right-click the content of the election,
In connection to use the project to find Internet Protocol (TCP / IP) after the election by clicking on [content],
You will find the original should be automatically IP position,
It changes into your customized IP,

IP location of the proposed fill: 192.168.1.11
Subnet mask into the proposed Zhen: 255.255.255.0
The default gateway of the proposed fill in: 192.168.1.1

Please keep in mind here, fill in the IP, is that, with your own set
Can fill in 192.168.1.2 ~ 192.168.1.100 should be no problem!

In this way on even its own network card IP.

Advantage is that
When you complete this configuration, the future will be your WINDOWS boot faster,
Because it do not go to spend time looking for other local area network whether there is a requirement should be why your IP.

Disadvantage is that
So if the share of direct and other IP connection, if it is not in accordance with the IP devices to share the scope of the division of IP,
Or connect with the internal computer network card and you have the same IP-based, the
Such conflicts will not be able to connect!

When you complete the above-mentioned actions, it can almost get to see the internal ADSL MODEM set!

(2) ready to connect to the ADSL modem's internal settings

ADSL MODEM then ready to look at the internal data Hello!

Line network connected to the ADSL MODEM, and then in the browser's page, enter http://192.168.1.1

At this time you will jump out of a need to enter the account password box!

If the model is that
Alcatel T07A (T07AW) or Tecom AR4031B:

Account should be: cht
Password in accordance with the north there are three different possibilities:
The north may be : chtnadsl
Central may be : chtcadsl
Southern may be : chtsadsl

Alcatel SpeedTouch 340, Culture and Sport or the whole Comtrend CT511-C:
Account number: (none, do not fill in )
password: 12345

Other models and then I do not quite know ...

If goes well, this should be able to enter the internal ADSL modem settings page,
Can see the relevant configuration information, as well as for change!

PS. If false or VDSL fiber optical generation of aircraft programs,
Account may be: cht
Password in accordance with the north there are three different possibilities:
The north may be : chtnvdsl
Central may be : chtcvdsl
Southern may be : chtsvdsl

(3) T07A or internal T07AW ADSL set numerical:

(i) Device Info:

ADSL INFO:
Mode: connection mode, there are G. DMT and ADSL2 + two sizes!

SNR Margin (dB):
Signal to noise ratio, the better, it is proposed to more than 7. Modem will automatically be judged.
If the room does not meet the value set for more than a modem may be automatically disconnected, and deceleration adjust to the quality requirements.

Attenuation (dB):
Attenuation value, the smaller the better, it is recommended to 30 below. (This is far away from the engine room on the ...)

Attainable Rate (Kbps):
Every time after the start ADSL modem, ISP and data will be the first test between the current network status and noise interference situation,
Determine the normal operation of currently available bandwidth of the largest, so this value will always change.

Rate (Kbps): Rate (Kbps):
For the fact the current operation of the modem bandwidth, each modem has re-opened after the value may change.
This numerical limit in accordance with the application of the maximum bandwidth, ISP restrict the room will be set.

And the present value than the above-mentioned lower Attainable Rate.
SNR Margin, if not quality, Attainable Rate values will drop, but also may cause the numerical decline followed!
Therefore, the network of poor quality, this value is also possible that frequent changes in the value of ...

Notes:
Before I had thought that the modem in the engine room Rate This value is set to apply for bandwidth value should be fixed.
But in fact, is not this way, this value is at that time as the network changes the quality of the ...

If the day of poor-quality network, Attainable Rate will decline, but also affect the value will be followed Rate down ...
If the day's network for better quality, Attainable Rate will increase, Rate value will be close or equal to room settings.

Therefore, Attainable Rate (measured up to the highest bandwidth currently), Rate (the actual operation of the current bandwidth), and the engine room set bandwidth, three is not the same as ...

Let me give an example to explain
If the engine room to help me set the download bandwidth of 11998 Kbps (around 12M of 12288K)

If the wire or with a better network for better quality at the time when
Attainable Rate may be 16159 Kbps, this time is the maximum Rate of 11998 Kbps.
(At this point the Rate theoretically can reach more than 14000, because there is a ceiling on the engine room 11998, so that is the maximum that would be it.)

However, when I used the wire or through a comparatively small relatively poor quality of materials or the network was poor,
Attainable Rate may be reduced to 12585 Kbps, this time into Rate of 10929 Kbps.

In other words, the modem inside Attainable Rate and Rate, are based on changes in network quality and floating values.
Rate the highest rate of no more than the engine room set bandwidth (fixed value, unless the room has changed again),
Rate and the rate would be slightly less Attainable Rate.

Software Version: modem firmware version.

PS:
12M/1M should be close to 12,288 / 1024
8M/640 should be close to 8192 / 640
However, in accordance with the quality of different networks, modems may be automatic deceleration ...

According to my modem as an example of the current situation saying:
Downstream (download) / Upstream (From)

SNR Margin (dB): 19.8 / 15.5
Attenuation (dB): 22.0 / 8.74
Output Power (dBm): 17.5 / 12.4
Attainable Rate (Kbps): 20425 / 1024
Rate (Kbps): 11997 / 1023

(ii) Able to get ADSL modem internal settings page,
In SETUP projects can be set to use some of the features inside.

As for Alcatel T07A (T07AW) can dial into the hardware,
ADSL MODEM allow IP sharing device has a dispensing IP functions,

However, I suggest that you do not change it to increase the burden on the!
So this may increase the load incompetent machines more easily overheat and crash it,

Hard mode dial and it will close off all of the PORT,
PORT need for some open software, but will add difficulties to use!
Dial-up mode hardware open method please refer to this appendix.

There are antennas T07AW models, it seems to open wireless network AP function,
Because I have only T07A models, the wireless network features, I have no way to test the!

(iii) hardware dial-up Internet settings (not recommended)
to T07A (T07AW) modem itself with automated dial-up Internet access and dispensing functions of IP

If we have to change hardware Dial-up (hard call) so that it automatically DHCP dispensing IP function, then
Go [SETUP] projects [WAN],
[Edit] Editor VCI 33 or 34 of this group,
(Change before jotting down their original settings. Some people are 33, some people is 34)

Election [Next] after it [Bridge] mode into [PPP over Ethernet] (PPPoE) mode,
And enter your account number dial-up Internet connection password!
If you use Taiwan hinet ISP, probably account are: 12345678@hinet.net
Application for change of a fixed IP person: 12345678@ip.hinet.net

[SAVE], and then click [SAVE / REBOOT] completed
ADSL data opportunity to re-boot automatically flash a red light two minutes,
This should be no need to go through a dial-up software, hardware can directly dial-up online!

Then, will jump on the DHCP allocated IP-related options, in the [SETUP] projects [LAN] settings,
Can set the automatic dispensing of the scope and the number of IP, this one can be to change.
Check to see sub-set is not the case. (Do not give up 192.168.1.1 to the IP, or else you will not forget the next login.)

IP Address: 192.168.1.1
Subnet Mask: 255.255.255.0

Check the[Enable DHCP Server]
Start IP Address: 192.168.1.2
End IP Address: 192.168.1.254

Dial-up hardware and automatic dispensing of IP enabled, as long as it is connected to this computer ADSL modem,
Network card will automatically be assigned to IP in the 192.168.1.2 ~ 254,
To their own IP can also be set, but must, as the first large projects, as ways to set up their own network card IP,
And regional and can not connect the computer configured the same IP. Otherwise, the conflict will not be able to connect to ...

However, there is a dial-up hardware default, will close all foreign domestic PORT,
This will be block a lot of software default to open PORT,

So you want to open certain PORT alone may have to go over there NAT set ...
(I did not go to settings, so I do not how well!)

In addition, hardware DHCP dial-up will be activated automatically dispensed IP capabilities,
ADSL modem processor to increase the burden of heat will increase
So, please do a good job relative to heat, otherwise it will be easy to crash ...

PS.
To change the software back to normal dial-up or ADSL modem to return before
Please go to the Edit [Edit] the content will be allocated to the account of Micronesia hard to remove after the [SAVE] storage,

Re-edit [Edit] once, will be [PPP over Ethernet] (PPPoE) mode to revert to [Bridge] model [SAVE] storage.
And then [SAVE / REBOOT], such as ADSL modem automatically re-boot finished it.

------------- -------------

Following on the ADSL MODEM T07A (T07AW) or on the network's other recommendations:
(Because no space to write an article for further specific articles, so on the end use for the appendix ...)

PS. If you are not equipped with Chunghwa Telecom's MOD service models is T07A (T07AW)
Setup can go over there to be found in the group VCI 36 to Disable to turn off,
Remove or simply removed. (VCI 33 or 34 is not going to move him)

PS. If you have severe BT needs,
This session of the ADSL modem may be all of a sudden you will be speaking to the爆掉,
Recommendations to buy DrayTek VIGOR 2104 this IP sharing device, (I still do not believe D licenses ...)
About 1600 ~ 1700 NT dollar, and that Taiwan is also good to use!

PS. Chunghwa Telecom, a move will be allocated to eight floating IP to users, (also may apply for change 7 floating IP +1 fixed IP)
This means that 8 individuals at the same time allow the importation of used ADSL dial-up account passwords way line,
Dial-up number 4 below, as long as a T07A (T07AW) enough, it is behind its four LAN ports.
If there are 5 to 8 individuals will need to purchase another HUB.

If you are a landlord or inconvenience to other people dial-up account passwords, or to the other side may help you to network with the Internet ADSL Small chaos buy
Or to use more than eight individuals,
Cases have more than dial-up mode using the hardware!

As for the hardware allocated to start the automatic dispensing IP model,
A bit budget (1,600 yuan from top to bottom),
Can purchase a single IP sharing device access in the back of ADSL MODEM for dispensing action,

Money can also be referred to the light before the opening of the T07A (T07AW) hardware dial-up function,
However, the event caused by heat more easily crash or overburdened ADSL MODEM CPU is very likely ...

PS.
On network management recommendations,
People have to restrict the use of control upload bandwidth!

Because the stuff can cause network problems, often not the download bandwidth use is too large,
Rather, it depends on the upload bandwidth to be used too much.

To 8M/640 as an example, the upload bandwidth of only 640 small K, equivalent to 80 large K.
About the use of the 30 ~ 40K, the network will begin a large LAG ...

To 12M/1M as an example, the upload bandwidth only 1024 small K, equivalent to 128 large K.
About the use of the 70 ~ 80K, the network will begin a large LAG ...

Therefore, more than a shared network, the need to strictly limit or prohibit SKYPE, such as BT Internet sharing software or use,
(To estimate VoIP, SKYPE about 30K upload bandwidth use, IM (MSN or YAHOO Messenger) instant messaging software, about 15 ~ 20K)
If there is no bandwidth sharing hardware devices (very expensive), it can only rely on the management of the prohibition and restriction on!

To further mentioned that when the landlord or network managers how to deal with the network to share experiences,
May have marked a lengthy report on this in the first skip did not mention the ...

II. ADSL modem T07A (T07AW) cooling hardware articles:

[Computer] ADSL modem T07A (T07AW) ADSL MODEM thermal cooling solution crash

1. T07A (T07AW) modem is a stable aircraft types it?

I rented a place before almost all of my network management,

Chunghwa Telecom used ADSL MODEM,
Originally, the white turtle ALCATEL Alcatel Speed Touch 340,
This ADSL MODEM few mistakes when the machine!

It is the IP sharing device DLINK plastic shell DI-704P B version of the relatively incompetent,
Slightly larger than the entire traffic crashes frequently, or is no access to settings page,
(DI-704 is a steel version of the general incompetence of a large flow into the settings page will be very slow ...)

Replaced by the IP-sharing DrayTek VIGOR-2104 after the device was much better!
This chapter is not to discuss the main IP sharing device, in this skip without mentioning ...

Later, ah,
8M/640 upgrade 12M/1M after, White Modem Speed Touch 340 can only run 8M,
Therefore, it was replaced by New Black Modem, ALCATEL T07A (or T07AW) ...
(T07A is no antenna, T07AW is antenna)

However, the problem came about a week you would be out every time,
This new modem T07A (T07AW) is not what I want to complain about, really is very easy to crash!

(This proves that the heat in the same conditions,
ALCATEL Speed Touch 340 is bette than T07A (T07AW) on against heat;
If you are using 8M, the modem is a Speed Touch 340 Do not insist on changing T07A (T07AW))

And hot when the machine is dead when a state, even the wrong ALARM will not be bright red,
Must re-switch its power will be back to normal ...

Later, I opened after the modem to see if there is no burst open capacitance!
But a little while after use, to touch it the biggest deal there is no cooling of the wafer surface,
OH ~ NO! Will be hot ye!

You put your fingers lightly on the chip, if you feel warm ,probably 50 degrees in the following,
If the chip will be pumping iron to your hands, it said the temperature may have been broken for more than 60 degrees,

There's largest chip should be this T07A (T07AW) ADSL MODEM its CPU the bar!
Do not dare to do it cooling measures, but also really brave ah!
(Even my K7 BARTON 3200 + CPU, the temperature is 1-70 degrees death for you!)

I do not know that the chip can be the normal operation of the temperature is several times less than
However, the Council does not increase the level of hot heatsink, then they would have no way of knowing the situation occurred,

When the machine may be relatively easy to detect, but also know that going to re-boot,
If the data packet error rate of increase, or slowing down the network would have been enough ...

This also makes me have cast grave doubts on the operation of the model stability,
Do not know that the occurrence of frequent crashes, whether related to overheating?

But when the summer comes, the chip really has the ability to bear the high temperature it?
Therefore, in order to improper This ADSL MODEM white mice,
But also to the stability of the network had to be the chip to make a simple cooling to deal with!

As this method is when the summer heat to tell everyone,
However, those who havo nothing to do, can buy me that the props,
In order to maintain the speed of your network security and stability!

2. To strengthen the thermal efficiency of the modem in order to avoid when the T07A (T07AW) of white rats?

To strengthen the chip cooling There are two ways:
(1) the installation of a heat sink, increasing the chip surface area of heat!
(2) increase the fan to enhance the speed of thermal convection!

Apart ADSL modem is very simple, as long as the bottom four screws after release, click on the chassis a little dial on the open;
Open, first check each cylindrical capacitor is not all in good condition did not burst open. (Should not burst!)

Then, the
Your modem center-right has a relatively large number of chips,
When you boot after the opening of the operation for some time to look at the wafer surface gently touch, see if it is will be very hot.
If now is very hot, because it shows that the summer will die one more ugly,

People not want to die or those who wish to prepare,
Go buy about 4 cubic centimeters are in a dedicated heat sink and thermal conductivity two-sided patch,

No parts or do not know what to buy licenses,
Directly suggest that you buy the COOLER MASTER Northbridge heatsink (PAC-P01), about 130 yuan,
North Bridge heat sink and this is just a modem about the size of the chip.

Airport authorities in the data state,
Those double-sided heatsink attached to the film, and then tore off the other side of the heatsink gently charge on the chip,
So successful in the sticky heat sink on the chip has been!

The shortcomings of doing so is that
The high heat sink (4 cm), so you will no longer be able to cover the case of data returned, and
Therefore, you will come to the modem will not be on the juice back into place like ...

After the installation of heat sinks, so the chip itself, heat will be transmitted to the heat sink, you can increase the heat dissipation surface area,
The chip will be able to bear the high temperature down a little bit
This will complete the simple cooling work!

If a little more about the weather or really hot, then
I suggest also can use a 8 * 8 or 12 * 12cm small fan next to stand in MODEM blowing it!
The use of less noisy fans 12cm ...
(Those who are not afraid of noise can also be installed 4 * 4 small cooling fan directly locked in the heat sink on the hair)
Received power at your own computer chassis with power supply lines! (Some external power supply IDE hard disk can also be used exactly)

However, when one day to be returned when the ADSL modem,
Remember to unplug heatsink, and the ADSL MODEM back of the chassis lock ...
