I think it’s related to a driver as all windows update installs is drivers after reformat.What software is on the machine, specifically anything you have added?
When it stops working does it loose access to the whole internet, ie nothing works or is it restricted to steam, uplay and windows updates?
Can you ping your gateway (prob 192.168.1.1) when its faulty? (drop to command prompt, type ping 192.168.1.1)
And again what virus checker ect?
VPN working tends to indicate there is an issue with your network settings, when its playing up drop to the command prompt and type ipconfig /all and copy the text into a reply for us to see.
All I’ve got installed is gpu drivers and uplay. Firewall is windows default. Literally bare minimum. Tried pinging that address you have me. Came back fine. I can’t reply to you on my laptop as it does nothing when I click send. Sure it’s related to the issue I have. Do you have what’s app? I could send you pic on there ?
This problem only started after I reformatted laptop. Was fine prior to that.
I’m on a 4G mifi connection as I work at sea. Along side at moment.
