We have a PC connected to the server on our upper floor as the Wifi reception up there isn't the best. Since yesterday there has been no Internet connection possible upstairs, despite no troubles with the Wifi on other devices, and despite it having worked for years. Wifi is also not connecting. The issue appears to be: The DNS server is not responding No resolution options work. Any ideas on what the problem might be? I have gone through the Swisscom resolution steps and nothing made any difference. Cheers
