What is the reason why the computer network speed is very slow after the fiber is connected to the r

Interference between routers, or the router itself is unstable.

Why is it that the computer is connected to the optical modem and the Internet is very slow to connect the router?

Why is the computer connected to the optical modem Internet fast, even the router Internet is very slow, the network cable is directly connected to the computer network speed is normal, if the router network speed is slowed down in the middle, there are two possibilities for this failure: one is that the performance of the router is too poor; Another reason is that the quality of the network cable is too poor, which affects the network transmission speed. For this fault, it is recommended to replace the corresponding hardware to deal with it, because the wireless router and network cable are the two key components that affect the performance of the home network.

Replace a powerful router: In a home network, the router is responsible for the data** and acts as the data hub of the home network. If the performance of the router is too poor, the network speed will definitely slow down.

Hope mine is helpful to you, thank you and have a great day!

Summary. The computer is connected to the optical modem and the Internet is very fast, and it is connected to the router. Internet access is slow for several reasons:

1. Disconnect other computers under the router (wired and wireless clients), make sure that only wires are connected to a computer under the router, and conduct a network speed test on the computer through popular resources such as Thunderbolt and BT software or through the official speed test software of the local operator. Without connecting to the router, the computer is directly connected to broadband and uses the same software** the same resources to test the network speed. Under normal circumstances, the test speed will be close to the bandwidth value you applied for when the router is not connected, if there is a large gap with the bandwidth value you requested, you can consult the local broadband operator to solve the problem.

If the tested network speed is close to the requested bandwidth value, it generally means that there is no problem with the network speed. After connecting the router, if the test speed is significantly lower than the requested bandwidth value, please proceed to the next step. 2. Check the settings on your router.

Check whether the router has the IP bandwidth control function enabled, and if so, turn off the function and confirm the speed again. 3. Check your computer's settings. Check whether the speed test computer has turned on P2P software or its hidden process, the more typical software is PPS, PPTV, BT, Thunderbolt and other **or**software, even if these software does not carry out any **operation, it will continue to upload data, thereby affecting the network speed.

Why is it that the computer is connected to the optical modem and the Internet is very slow to connect the router?

I'm sorry I don't understand, but can you elaborate on that?

The computer is connected to the optical modem and the Internet is very fast, and it is connected to the router. Internet access is very slow because of the following reasons: 1. Disconnect other computers under the router (wired and wireless clients), make sure that only one computer is connected under the router, and conduct a network speed test on the computer through Thunderbolt, BT and other software **popular resources or through the official speed test of local operators** and official speed test software.

Without connecting to the router, the computer is directly connected to broadband and uses the same software** the same resources to test the network speed. Under normal circumstances, the test speed will be close to the bandwidth value you applied for when the router is not connected, if there is a large gap with the bandwidth value you requested, you can consult the local broadband operator to solve the problem. If the tested network speed is close to the requested bandwidth value, it generally means that there is no problem with the network speed.

Why is it that the computer is connected to the optical modem and the Internet is very slow to connect the router?

Hello dear, happy to answer for you. The reason why the computer is connected to the optical modem is very fast and the router is very slow to access the Internet is that the computer accesses the Internet through the router, and the network speed is very slow. This shows that the router is not a real Gigabit router, or the quality of the router is not good, the configuration is poor, and the performance is lower than the performance of the wifi chip that comes with the fiber optic modem.
