I had similar errors in my Network log, but open a Command Prompt (Admin) and enter -
netcfg -d
shutdown /r /t 00
Then go into Device Manager after the reboot, click on View/Show hidden devices/Network adapters and ensure they are all present such as the wireless and Ethernet adapters.
If they aren't, then repeat those two cmds and check Device Manager again after the reboot.
Open a Command Prompt (Admin) and enter these cmds but let me know if either fail.
The resetlog.txt cmd may have an hiccup in it but should complete.
netsh winsock reset
netsh int ip reset resetlog.txt
ipconfig /flushdns
ipconfig /registerdns
shutdown /r /t /00
After the reboot go Start - type reliability then click on View reliability history when it comes up to see if you have any red crosses for today's date.
