Why does my DNS change (and break) at regular intervals?

dns

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?
