1, can you ask people who live near the same community whether the internet speed is the same as yours? If so, it is a telecommunications problem. You can complain more. I have met many 2m adsl broadband users, whose actual speed can't even reach the level of 1m broadband. After many complaints, the network speed will be improved.
2, you restart your router (that is, turn off the power of the router and then turn it on), because sometimes if you turn on the router for a long time, the cache inside will slow down your network speed all the time, even sometimes only half the speed. If this is the case, the speed will increase immediately after the restart.
You should understand that the maximum download speed of 2m telecom broadband is 250k per second, which is ideal. If your maximum download speed is between 200-250K per second, it's normal (the customer service of telecom will cheat you that the broadband speed of 2m is normal to 180K per second, don't believe him, and complain if it is lower than 200K per second).
4. See if there are some psp uploaded and downloaded software running when your computer is turned on, such as those online movie and television software (such as popular movies, uploading and downloading movies you have seen will take up 90% of your bandwidth when you turn on) and downloading software. If these softwares are turned on (or you turn them on manually), even if you don't download anything, it will upload and download some exchange information at any time (such as Thunder, you turn it on without downloading anything).
5. The reason of network card driver and hardware is almost nonexistent. As long as you can get online, your network card is absolutely competent.
6. Make sure that no other computer is connected to your router. If your ADSL router is connected to a wireless router, your wireless signal may be stolen. You can determine this by looking at the machine code of the computer currently connected in the wireless router.
Finally, I tell you for sure. . . Perhaps the most likely reason for your slow internet speed is the telecom problem. . . .
Go to the official speed measuring website of telecom to measure the speed.
