Hello,
Thank you for posting in Q&A forum.
It seems that you have done a lot of checks to solve your network speed issue. Based on the information you provided, the problem may be on your computer. Sometimes, the driver of a network adapter may cause speed limitations. You can try updating or reinstalling your network adapter driver to see if there are any improvements. Additionally, you can try resetting network settings or disabling and then re enabling the network adapter in Device Manager. I hope these methods can help you solve the problem.
Best regards,
Jill Zhou
