Many home broadband networks have been upgraded to 300M and 500M, but people feel that the internet speed is still as slow as before. Why is this?
The author believes that the main reason for the slow network speed after the home network upgrade is the router!
Most home users only pay attention to the long-term modem (optical modem) when upgrading the home network, and neglect to upgrade the wireless router, but the network that everyone often uses is through the wireless router. Most of the home routers before 2017 were 100M routers, that is, the maximum speed of the network interface behind the router was 100M.
100M network port
When the broadband is greater than 100M, such as 200M, 300M, 500M broadband, a gigabit wireless router must be used, and the network speed can exert maximum performance.
Gigabit Ethernet port
Also note:
(1), some routers have a gigabit wireless, but the wired interface is 100M. However, some businesses still say that they are gigabit routers when they are promoting, and they fool some users who don't understand to buy.
Therefore, when you buy a gigabit router, you must pay attention to check whether the router's WAN port and LAN port are 100M or gigabit, and you must choose a wireless router with a gigabit WAN port or a gigabit LAN port.
(2) In addition to the router, you also need to ensure that the network cable connecting the router, computer, and modem supports Gigabit. Whether the network speed of the positive broadband is only 100M at most, which cannot reach the maximum network speed.
Having said that, do you have a certain understanding of the slow Internet speed? If your home's Internet access bandwidth is above 100M, use a gigabit router to give full play to the bandwidth speed to achieve a smoother goal. Are you clear?
Finally, let’s take a look. We often talk about 100Mbps broadband, 300Mbps wireless routers, and 100M/Gigabit ports. The “mega” (M) here refers to the rate unit Mbps, and 1Mbps means 1 megabit per second transmission. rate. Many friends of
have this question: Why do I have a bandwidth of 100M, but only 12M for mobile/computer downloads?
That is caused by different units of . The unit of data in the network is bit (b), while the smallest unit of data storage in mobile phones and computers is byte (B). The relationship between
bit and Byte is: 8 bit=1 Byte
so 8Mbps=1MB/s
In other words, if your home broadband is 100Mbps, the maximum download speed you can get is: 100Mbps/8=12.5MB/s, considering the rate The general download speed will be less than 12.5MB/s.
