Afther Months this bug is still here. Yesterday my PC was forced to update to Win 11 24H2 and I've got internet problems. Randomly when I reboot PC it goes well, internet cabled connection works fine but other times when I start my PC Internet doesn't work, websites open after ages or don't open at all. I had before and now with current windows 11 version setted in my PC a static IP address but the issue is still here
I know you would have thought they would have fixed this problem by now. After I got the recent update, I thought it had went 2 days coming out of sleep mode with Internet okay, but this morning it didn't, what I have been doing is waiting for the recover from sleep to complete then right clicking on the Network icon and selecting Network Connections, Disabling the connection waiting a minute then0 Enabling it., which is all that restart Adapter does.
By the way I am just an elderly home user with 2 PCs sitting side by side and a Laptop, all running 24H2 now, and am only having the problem on the 1st PC that was updated, the other PC and Laptop don't show any Network problems at all - all 3 are using Ethernet not WiFi
