Win11 25905.1000 Network Fault

My computer has a network connection rate of 10Mbps every time I turn it on, but I have a broadband of 100Mbps. At this point, I only need to disable the network card and then enable it, and the speed will be restored. It has been ruled out that there is a problem with the operator or network cable. Is it a system issue? And how can I solve it?
