Press your Windows key and R together to bring up the Run open box or go from Start to Run. In the Open box, type cmd then press enter. A black form shows up and at the Command Prompt, type
netsh int ip reset reset.log
including all the spaces and press Enter. That may help but in any event, then type ipconfig /all (again, including the space) then right click anywhere in he rblack form and press Enter. That clipboards all the information on that form and Control V will bring it back in a Quick Reply box back here so we can see what's going on.
