I have a laptop running Windows 7. Up until recently, everything was fine. We have multiple devices in my house connecting to the one access point with no problems. No issues with ISP. Now my Windows 7 PC DNS settings change every minute or so.
Before the problem occurs if I do an ipconfig /all I have two DNS settings (primary/secondary) and everything is fine.
After a short period of time this change to a sole DNS, 10.0.0.1. Webpages no longer resolve.
If I do an ipconfig /renew, this fixes the problem.
I have tried uninstalling various programs I thought might be related but the problem persists. Any ideas of potential causes?

Unexplained DNS setting changes are very alarming because it is one of the most popular tactics used by malware to redirect its victims.
Changing the DNS settings also requires Admin Privileges. Considering this is a home computer, I further suspect this could be either malware or a very poorly written program.
But changing to 10.0.0.1 is a very very odd setting.
After checking your computer for malware, I'd next trim your startup processes or at least list them in a text file for others to examine for possible misbehaving 3rd party processes.
