To upgrade gigabit broadband, which devices to replace

The first is the light cat.

This is a telecom operator.

provided,Generally supported,If you buy it yourself, you have to distinguish whether it supports gigabit。

The second is the network cable, which used to be generally five types of cables.

Category 5 lines support up to 100 megabits, more than 100 megabytes will be used to more than category 5, you can check the logo above the network cable, cat5 represents category 5, cat5e represents category 5, and so on. If the transmission distance is close, you can choose more than Category 5, and if it is far away, it is recommended to use more than Category 6 network cables.

Then there is the router, the first thing to choose a router is to see whether the WAN LAN interface in its parameters supports 1000M, these two interfaces must be supported, some manufacturers, merchants in order to save costs and increase sales, often play word games.

In the outer box is marked 300M, 1200M, etc., in fact, these routers only have the LAN interface, which is Gigabit, and the WAN port is not Gigabit, so that it can only be transmitted within Gigabit in the LAN, but the external network.

Access can not do more than 100M network transmission. Therefore, it is necessary to see the parameters of these two interfaces, and it is necessary to support Gigabit at the same time. There is also the wireless wifi parameters of the router, which must support the 5G frequency band, and it is difficult to reach the highest rate in the frequency band used before.

The next thing is to check whether the network card of the computer supports Gigabit, and the network card here is divided into wired network card and wireless network card.

The wired network card is the network cable socket on the computer to support gigabit, and the network card integrated by the early computer motherboard may be 100 gigabit, like this kind of external gigabit network card, which is generally cheaper. There is also a wireless network card, which depends on whether it supports the 5G frequency band, and only in the 5G frequency band can the maximum speed be perfectly reached. Now the new computers basically support Gigabit, if it is an old computer, you need to check its specific configuration parameters to choose to replace and upgrade.

There is also a check whether mobile phones, tablets, TVs and other devices support gigabit, here to teach you a simple identification method: if it is wired access, see whether its interface parameters support gigabit, if it is a wireless network.

It depends on whether it can receive the 5G band signal in the router's wifi, and if it can receive and connect to the Internet, it is supported. However, even if these devices do not support it, they can still support the use of frequency bands to surf the Internet, but they can't reach the maximum speed.

I think it's useful to remember.

First there is the broadband modem, then there are routers, switches (if any), and network cables.

To upgrade to Gigabit broadband, the following devices need to be replaced:

1: First of all, it generally supports the optical modem provided by telecom operators. If you bought it yourself, then score clearly and see if it supports Gigabit.

2: Secondly, the network cable. In the past, Category 5 lines were generally used, and Category 5 lines could support up to 100 megabytes.

If it is more than 100 trillion, more than five categories are used. For more information, check the logo on the network cable. cat5 stands for five classes, cat5e stands for five classes, and so on.

If the transmission distance is short, you can choose more than five categories. If it is far away, it is recommended to use more than six types of network cables.

3.Then there's the router. When choosing a router, the first thing to see is whether the WAN LAN interface in its parameters supports 1000M, and both interfaces must support it.

In order to save costs and increase sales, some manufacturers and merchants often play word games, marking 300m, 1200m, etc. In the outer box. In fact, only the LAN interface of these routers is Gigabit, and the WAN interface is not Gigabit, so Gigabit can only be implemented in the LAN.

So it is necessary to see the parameters of these two interfaces, and support Gigabit at the same time. There is also the wireless wifi parameters of the router, which must support the 5G frequency band. It was difficult to reach the highest speed in the frequency bands used before.

4: Then, check if your computer's network card supports Gigabit. The network cards mentioned here are divided into wired network cards and wireless network cards.

A wired network card is a network cable socket on a computer that supports Gigabit. The early integrated network card of a computer motherboard may have been 100 megabytes. For example, you need to add an external gigabit network card, which is generally cheaper.

There are also wireless network cards. This depends on whether the 5G band is supported. The highest speed can only be perfectly achieved in the 5G band.

Nowadays, all new computers support gigabits. If it is an old computer, you need to check its specific configuration parameters and select Replace and upgrade.

If it is wired access, see whether the interface parameters support Gigabit; If it is a wireless network, see if it can receive the 5G band signal in the router's wifi. If it can receive and connect to the internet, it will support it. However, even if these devices do not support it, they can still support the use of frequency bands to surf the Internet, but they can't reach the maximum speed.

For 200M telecom broadband at home, it is necessary to change the gigabit router.

If you want to run 200M broadband, you must use a gigabit router, but if you change a gigabit router, you may not be able to run to 200M.

The router used for 200 megabyte broadband must be greater than or equal to this rate, so a 300 megabyte wireless router or gigabit router is generally required. Another important thing is that the network cable interface of the 300 megabyte or 750 megabyte router is generally 100 megabit, which is the main factor restricting the 200 megabyte broadband, and the 100 megabyte interface is obviously to lose the general speed for the 200 megabyte broadband, so the 200 megabyte broadband is recommended to use the gigabit port router.

Other requirements

The five types of network cables and the previous types only support the rate of 100 megabits, so even if the router and other network equipment are gigabit, it is useless, and in order to achieve the speed of more than 100 megabits, you need to use network cables that support gigabit speeds, such as super five cables, six cables, and super six cables.

The requirement for the computer is that the computer's network card should be able to reach a rate of more than 200 megabits, and it is recommended to use a gigabit network card, which generally cannot play a speed of 200 megabytes at full speed.

When it comes to internet speed.

Improve, maybe the first thing that comes to everyone's mind is that you can replace the router, replace a gigabit router, and naturally you can directly cross from 100 gigabit bandwidth to gigabit bandwidth.

In fact, this view is relatively one-sided, if you want to really leap from 100 Gigabit bandwidth to Gigabit bandwidth, first of all, you need the upgrade support of the bandwidth itself, and then you need Gigabit optical modem.

to convert the photoelectric signal, and then you need a gigabit router to support it, but there is also one of the most important things, that is, the network cable.

Many people may not know whether they can use the gigabit network, and there is a difference on the network cable, such as the super five branch bend network cable that we use most often.

There is a big difference with the super six network cables.

First of all, the general super five lines.

They are all used in 100 megabit broadband, and although the super five lines support gigabit networks, but this is also relative to the previous ordinary five types of lines, if you need higher network speed support, then you need to take Zheng super six types of network cables, the bandwidth support it provides can reach twice that of the super five lines, this is the biggest difference between the two.

In home networking, the bandwidth actually used by users is the minimum of ingress bandwidth, modem bandwidth, network cable bandwidth, and wireless router bandwidth. Therefore, in response to the subject's question, in order to fully exert the 200M home bandwidth, in addition to the wireless router needs to be replaced with Gigabit, it is also necessary to check whether the modem is greater than 200M, if there is only 100M, it needs to be replaced together.

There are four key points in home networking:

1. Household bandwidth, now several major network service providers basically provide optical fiber to the home, this figure takes optical fiber as an example, ASDL is similar to this, the household bandwidth is generally purchased from the service provider, and the higher the bandwidth, the more expensive it is.

2. Modem, that is, what we usually call cats, optical fiber to the home needs optical modems, ASDL to the home needs the corresponding cat, the bandwidth of the modem is only limited to a few modes, for example, I use China Telecom optical fiber, the bandwidth they provide is 100M, 500M, 1G (other service providers should be similar to this), the bandwidth of the optical modem can only be greater than the home bandwidth, in order to fully play the role of home bandwidth.

3. Network cable, the unlimited router needs to be connected to the optical modem through the network cable, and now the basic ones sold on the market are gigabit network cables, so there is generally no problem with this, unless you use an old low-speed network cable.

4. Wireless router, it is a transfer station for various devices to access the network, wireless devices (mobile phones, tablets, laptops, etc.) or limited devices (desktop computers, network TVs, etc.) are connected to the router, and through it are connected to the optical modem, and then connected to the Internet. In order for the bandwidth of the modem to be fully utilized, the bandwidth of the unlimited router must be greater than the bandwidth of the modem, and there are two main wireless routers on the market: 100 Gigabit and Gigabit.

Finally,According to personal experience, I will give the subject a little advice,Wireless routers generally need to be purchased by themselves,And optical modem service providers sometimes give away,Provided that you pay a certain amount of broadband fees,Or some other agreements,You can consult the network service provider first,Maybe you can get one for free。

For home 200M broadband, it is necessary to replace the gigabit router, otherwise the network speed will be limited to less than 100m, which will invisibly waste broadband resources, so in order to get a higher speed network experience, it is very necessary to replace the gigabit router.

I think of course you can, but your maximum speed will still only be 200 megabytes.

I think it can be replaced, but it's not necessary, because your broadband can't play the maximum performance of this router.

There are two ways to upgrade mobile broadband:

1. Call **10086 to transfer to manual customer service, inform the customer service that the bandwidth needs to be upgraded, and the other party will arrange relevant business personnel to handle the upgrade business.

2. Go to the mobile business outlets to handle the upgrade business: 1. Bring the relevant documents to the counter and wait in line. 2. Tell the staff that they need to upgrade their broadband demands, select the appropriate one, and fill in the relevant materials. 3. Wait for the staff to come to the door.

After the application is completed, restart the network, check whether the upgrade is successful, and ask the staff to solve the problem in time if there is a problem.

Broadband data transmission rate is one of the important technical indicators to describe the data transmission system, theoretically speaking, the maximum broadband network speed of 100m can be reached; The broadband network speed of 200M can reach up to 25M s; A broadband speed of 300m can be reached. When actually used, the network speed will be affected by routers, network cables and other equipment, and the speed will have an error of about 1m-2m.

Optical fiber broadband converts the data to be transmitted from electrical signals to optical signals for communication.

At both ends of the Huji optical fiber, pants are installed, and there are "optical cats" for signal conversion. The difference between optical fiber broadband and ADSL access mode is that ADSL is electrical signal propagation, and optical fiber broadband is optical signal propagation. Optical fiber is the most ideal one of a variety of transmission media in broadband network, which is characterized by large transmission capacity, transmission capacity, low loss, long relay distance, etc.

Optical fiber transmission uses wavelength division multiplexing, that is, the data of multiple users in the cell is fused into high-speed signals using PON technology, and then modulated to different wavelengths of optical signals are transmitted in an optical fiber. <>
