What does wired broadband mean What does band bandwidth mean?

Band bandwidth refers to the width of your router's transmitting frequency.

20MHz corresponds to 65M bandwidth, good penetration, and long transmission distance (about 100 meters). 40MHz corresponds to 150m bandwidth, poor penetration, and short transmission distance (about 50 meters). And the 300M of your router refers to the transmission rate (maximum transmission rate) of your router is 300Mbps; It is commonly known as Internet speed.

How to set the band bandwidth:

1. First of all, take the router out of the package and connect it to the external power supply.

2. Home routers usually have 5 WAN interfaces. 1 is the interface to connect to the WAN, alone on one side, and there are 4 [5 or 8 for larger ones] LAN interfaces, and the wireless router can be used as a wired router with 4 computers. Connect the WAN port to the connection cable of the external network - usually this cable is an RJ45 connector, which can be plugged into the WAN port of the router.

3. First of all, you need to log in to the router to set up, there are two ways to log in to the router: wireless login from wifi from the computer, or wired login from the LAN port [a twisted pair cable is required]. In the case of wired login, the usual IP address is:

Wireless does not require an address. In general, the login user name of a router is admin, and the password is admin.

Band bandwidth refers to the bandwidth of the router's transmitting frequency:

1. The corresponding broadband is different

20MHz corresponds to 65M bandwidth, good penetration, and long transmission distance (about 100 meters).

40MHz corresponds to a large 150m bandwidth: poor penetration, and the transmission distance is close (about 50 meters).

2. Different channels:

20MHz is a single channel and 40MHz is a dual channel.

The current common router single-channel:

Up to 150m, dual channel can reach 300m.

Wireless routing work is divided into several standards according to different frequency bands, namely 11a, 11b, 11g, and 11n. Among them, the different working frequency bands also lead the lead key, resulting in different transmission speeds. 11n can be used between 11b and 11g, automatic conversion.

As far as normal users are concerned, it is generally necessary to choose a broadband band of 20MHz, which will be more stable.

After the popularization of the Internet, everyone's requirements for the Internet are higher, so there is a broadband Internet. We can explain broadband networks in a literal way, that is, to use a wider frequency band transmission network to make the network faster. Broadband networks are instead of transmission networks that traditionally use ** lines with smaller frequency bands to carry out the transmission network with larger frequency bands.

There are many ways to use broadband Internet access, and the most commonly used ones are cable TV Internet access and ADSL. Cable TV Internet access is a cable transmission network that uses the fourth channel to transmit images and sounds. Because network data and cable TV signals can be transmitted on the same line at the same time, as long as a modem is installed at each end of the cable line (the operator and the consumer), the child can use the so-called broadband Internet access at home.

ADSL is another way to access the Internet, and the translation of this full text in English is asymmetric digital subscriber line. No matter what its name is, we just need to know that it is the same as the traditional **pants is dialing method, and it also uses **line transmission network, the difference is that ADSL uses the frequency band that is not used**, so the Internet speed can be faster than the original **dialing method of Shimin, and it can also be used at the same time when surfing the Internet**.
