TCP IPv4 DNS server address keeps changing to a specific IP address (preventing internet access) when I need it to stay obtain address automatically

Control panel

Network and internet

Network connections

Wireless network connection

Wireless network connection properties

Internet protocol v 4 TCP/IPv4 properties

Sony laptop nearly new, windows 7, didnt have any problem until last week, have not changed any settings that i am aware of. One day I just could not get on the net.  Good signal to wireless router  but no internet access.  Eventually tracked prob down to above, each time i switch on i have to go back in to Internet protocol V 4 properties and select obtain DNS server address automatically

If I am on line for a reasonable length of time i have also noticed (once) it changed during a session

How can i get it to stay on obtain DNS server address automatically

How long have you been facing this issue?

I would suggest you to scan your computer for virus and check if it helps, it might be a virus issue.
