All Windows devices on our wireless home network are no longer able to browse the internet. The choice of browser does not matter. All iOS devices can still browse without problems.
I have tried the following while working with an elevated command prompt:
Ipconfig /release Ipconfig /renew Ipconfig /flushdns
None of those commands changed anything permanently although on a couple of occasions, the /flush temporarily allowed me to browse but it didn't last more than a few minutes.
in combination with ipconfig /flushdns
Checked internet options and confirmed that it is not using a proxy.
Also confirmed that it is automatically getting an ip address and a dns server address.
No viruses found on any of the windows laptops and no rootkits either.
I can ping an IP address but not a URL.
Not sure what to try next. Ideas???
