I use telecom broadband, so let's just talk about telecom! At present, the installation master of telecom won't give you the broadband account number and password, because the operator is afraid that you can't get online if you log in to the optical cat and change your settings. On the other hand, operators can also use your password to remotely control your light cat and modify its configuration. In this way, even if the light cat has some minor problems, the maintenance personnel can solve them through remote configuration without on-site maintenance, saving manpower and time costs.
Another important reason is that the address of telecom broadband is still IPV4, and it has not been upgraded to IPV6. The address of IPV4 is limited, and it is said that it was used up last year. If public IP is used, the cost is higher for operators. Therefore, users are generally not given public IP now, but many users use a public IP, which is dynamic IP. Therefore, in the default mode, the light cat will dial up the Internet directly, without using the router to log in to the broadband account password to access the Internet. However, because there is no public IP, it is difficult to connect home computers and other external network devices remotely.
If you want to log in to Guang Mao for simple setup, you can look at the label on the back of Guang Mao, which should have the user name and password on it. If the maintainer has not changed the password, you can log in to Guang Mao backstage normally with the default account and password. However, the authority of this account is relatively weak, and only some simple configurations such as self-contained WiFi can be set, and even the online mode of the light cat cannot be changed. Therefore, if you want to dial-up the Internet through the router, you must ask the maintenance personnel of Telecom for the password of the administrator account in Guang Mao.
When I first installed broadband, I also complained to Telecom about it, because my broadband used public IP before upgrading to 200M, but after upgrading to 200M, it became dynamic IP, which brought great inconvenience to my work. But the customer service of telecom actually asked me to find a tutorial online to crack the light cat. It is estimated that it is also because there are regulations in the telecom that customer administrator accounts are not allowed, but the customer service was complained by me and I made the best decision in desperation.
But later, I searched the tutorial online and found that the light cat that Telecom gave me was an upgraded version, which was very troublesome to crack. Later, I had no choice but to call the installation master of telecom and give him 100 yuan. Finally, I got the administrator account from him.
So my experience is that if you want Guang Mao's account number and password, you can only ask the installer directly, and you have to give the other party a little sweetness. However, for me, 100 yuan is not too much. After getting Guang Mao's account number and password, surfing the Internet is also convenient, which is quite cost-effective in general.
Obviously, broadband masters are making extra money themselves. It should be a line for several users. Of course, I won't give you the password. If I give you the password, other families can't surf the Internet. But now the general optical fiber installation will save this information. You only need to plug in the router to get the dynamic ip.
If it is a group rent, this phenomenon is more common, because it is contracted to a third party, and it can be used directly when plugged in. There is no need to install equipment at all, just need the installer to pull a cable for you and connect a router to surf the Internet.
If it is in a residential area, this phenomenon is impossible. You just need to find out which operator the network cable belongs to, and the master will solve the callback problem for you within half an hour. If there are two users, then the master who installed the network cable for you before can be gloriously laid off. There is no doubt that it is possible to give you free broadband for a few months.
If you don't want to find an operator, just download a p2p network terminator on the computer, unplug the router, plug the network cable directly into the computer, open the software and scan the whole network. As long as there are other users surfing the Internet, it will be directly disabled, so that the whole network traffic can be yours, or directly establish a network white list. As long as you don't add it, you can't get online.
At present, the newly installed broadband optical cats are all multifunctional optical cats, integrating broadband+router +IPTV+ telephone functions.
Take the mobile phone light cat as an example. Generally, LAN 1 is a gigabit network port, LAN2-4 is a 100-megabit network port, and LAN2 is a dedicated port for IPTV. Cable access to TV set-top boxes must be verified by signal login, and telecommunications is similar.
There is a broadband account password asked by the landlord. After the computer or mobile phone is directly connected to Guang Mao, log in to the background setting interface of Guang Mao (you must log in to the super administrator account, and the account password behind Guang Mao is useless to enter the setting interface, at least it is mobile), and you can see the dialing settings, which contain the broadband account password you want, because Guang Mao is already in the router dialing state at this time, and the router installed behind does not need any settings (DHCP dynamic IP can access the Internet by default).
The above setting method is suitable for broadband installation experts, because you usually don't reset the optical cat, and naturally you won't delete the settings inside, which saves them a lot of trouble and is convenient for most ordinary users. However, this multifunctional optical cat is only available in 50 yuan (the price of the Times will be given to you for free when the mobile phone is first installed, so we won't discuss it). The extra router we bought is not only this price, but also the average price of ordinary Gigabit network port routers is around 200 yuan (excluding ASUS, expensive network components [covering your face]). The routing performance of optical cats can be imagined, so many of us want to turn off optical cats.
Because LAN2-4 is a 100-megabit network port, the routing performance of optical cat is not good, so we need to change the settings, that is, the super administrator mentioned before logs in the background and finds the dial-up settings page, which has a setting and two options, which may be Chinese or English. Routing/Bridging: If you use light cat dialing, use the routing function. If you want to dial with your own router, please change this option to the bridging function. At this time, the LAN2-4 of the light cat can no longer plug in the network cable to access the Internet. LAN 1 connects the router WAN and resets the router to dial up the Internet.
If you follow the above settings, the IPTV network cable at home must still be plugged into the LAN2 in Guang Mao. This is a dedicated port, don't worry.
With broadband, there will naturally be a light cat. The function of optical cat is actually similar to that of router, but its performance is still worse than that of professional router. Now there is a function in the router called automatic dialing. You can dial automatically by setting the account name and password of the broadband account, and there will be a network automatically after the device is connected.
When I was in high school, optical fiber was not popular. I should use a telephone line to connect with an ordinary cat, which is a modem. That thing doesn't seem to have the function of automatic dialing. You can only set up a broadband connection in the system to dial manually, so you have to click "Broadband Connection" manually every time you turn it on, otherwise there will be no network.
If you have the spirit of tossing, you can directly connect the computer to the light cat and enter its management page, which also has many settings, among which you should be able to see the function of automatic dialing. Of course, I don't want to modify it without any suggestions. If I make a mistake, I can't even surf the Internet, so I have to ask the master for help.
Your problem is the same as when I installed broadband. The broadband master told me that because the cat and router they installed for us now are integrated, there is no need for an account and password. I tried it for a few days and found many problems, such as the use of multiple computers, unstable network speed and slow speed, but it is no problem to connect a computer directly to their equipment. Call the broadband master decisively, let him use his equipment only for the function of a cat, and then connect his router.
Actually, if you have an account password, you should call 10000. I didn't give my account password, including IPTV, in my rural area. The broadband master said he didn't know, and the default was random. Just dial 10000 to reset the password. My broadband master in the city will give the account password, including IPTV, so that the master can change the bridge mode and get the public IP. But the more expensive packages in urban areas are 169 200m in urban areas and 129 in rural areas.
Let me share my opinion.
With broadband installed, the installer said that there is no need to give an account password to access the Internet with dynamic IP. Actually, it's nothing. In the field of communication, as we all know, Guangmao has set the routing mode before using the account password.
A while ago, my home also installed telecom broadband. At that time, my family already had telecom light cats and fixed lines. As soon as the master came to the door, he connected the router to the cat, then tested the internet and left. In this process, he doesn't need to set an account password or provide it to me. Later, he found a friend of the operator to understand the situation.
In the past, optical cat can also set the routing mode, but operators will not do that, because once the routing mode is set, the performance of optical cat is not so strong, and the exchange of data during dialing will affect the performance of optical cat and greatly reduce the user's online experience, so it will generally be set to bridge mode, so that optical cat is a data forwarder, which will not affect the performance and thus have a better online experience. In bridging mode, we need to manually set PPPOE dialing, so we provided the account password.
Now, after so many years of development, the performance of the light cat has been improved, and the problem that dialing and forwarding data will reduce the online experience has long since disappeared. Based on the current situation of Guangmao, we can set the routing mode directly without providing us with the account password.
Moreover, it is actually very convenient not to provide the user with the account password. First of all, users don't have to remember such complicated numbers and letters. Secondly, set the account password in the light cat. When there is a problem, the maintainer can log in to Guangmao remotely, test whether there is a problem in the inner ring data link between the uplink device and Guangmao, and then quickly judge the problem according to the account number. In this sense, they can help users solve after-sales problems faster than before.
Generally, there are only elderly people at home. Sometimes you accidentally press the wrong key and lose the account password of the router, but the elderly can't do it. This situation is sometimes very helpless. Now you don't need an account password, just teach the old man which port to plug the line into.
I hope my answer can help the subject, and you can trust me privately if you don't understand.
After 3 years of broadband brother passing by, the following is just to attract jade. Welcome to correct me:
Optical fiber access is the mainstream. Everyone has to thank the national policy and mobile, otherwise the broadband price will not be so low [covering your face].
Generally, broadband brother doesn't give you the account password because every cat has a verification code. If the verification is successful, dial directly. This mode is called routing mode, that is, dynamic Ip, or it can be changed to use bridge mode to dial. Now it is generally the default routing mode, which is beneficial to future maintenance. Some users can't access the internet after changing their passwords, so they need to change their parameters at home, which leads to an increase in personnel costs. Actually, none of this is the point. The key is to be able to surf the internet normally, and the network speed is not slow. Here, I wish you all a happy New Year and all the best.
You may have been fooled by the master of broadband installation. If broadband does not have an account number and password, how to connect to the operator's network and realize billing? So why can I connect to broadband without an account and password? Let me talk about it in detail.
At present, the light cat at home can be said to be "wearing several hats", which not only realizes photoelectric conversion and converts optical signals into electrical signals, but also has routing function and realizes PPPoE dialing, that is to say, the light cat realizes automatic dialing, and users do not need to know broadband account numbers and passwords. Some routers also have the function of wireless WiFi.
It can be said that a light cat can meet our online needs.
The reason why the installer doesn't give users a broadband account and password is because Guang Mao works in the routing mode by default, realizing PPPoE dial-up connection to the operator's network, which is equivalent to first-class routing. The wireless router at home is connected to the optical cat, and the wireless router automatically obtains the IP address, which is equivalent to secondary routing.
Optical cat has two working modes: routing mode and bridging mode.
By default, Optical Cat works in routing mode, but its hardware performance is limited. If there are many internet devices and a large amount of traffic at home, the light cat can be said to be "overwhelmed", which may cause the problem of unstable network at home.
Usually, I will tell the installer to configure the optical cat as "bridge mode", so that the optical cat can only be used as photoelectric conversion equipment, and the wireless router PPPoE at home can dial up the Internet, so that the optical cat will no longer become the "bottleneck" of the home network.
In short, in order to simplify the user's operation and realize the "plug and play" of broadband, when users install broadband, if there is no special requirement, they will configure the light cat in routing mode to realize PPPoE dialing. Although this method simplifies the user's operation, it also has many shortcomings. Suggest users to call customer service and change the light cat to bridge mode.
