    LAN Upload speed suddenly low

    Hello

    My LAN upload speed suddenly (after Windows update) dropped to 1 Mbps. The normal upload speed should be around 60 Mbps. The download speed is still normal (about 600 Mbps). The wireless speed hasn't changed, it is still working well. This upload speed drop happened on one computer only. All other computers have full download/upload speed. Therefore, the network is working well. I also checked the cable, and the same cable on another computer works perfectly.

    I tried to fix the problem by following all suggestions in the thread LAN Upload speed suddenly extremly low - Microsoft Community.

    I tried clean boot, Windows repair, BIOS update, driver update, network reset, nothing helped.

    After a winsock reset (netsh winsock reset), even the download speed dropped to 30 Mbps and it took me several hours and a lot of luck to get back the 600 Mbps download speed. However, the upload speed is still less than 1 Mbps in average. It starts with 3 Mbps and falls down to 0 during the speed test.

    Any help is welcome.

    Hello Kauai, welcome to the Microsoft community, I'll be happy to help you today;

    I understand that the internet upload speed is low on Windows 10;

    What exactly is your PC model and manufacturer?

    If it's a desktop, what exactly is the model and manufacturer of the motherboard?

    Before answering the question I suggest you try the solutions provided in the link below:
