It appears that Microsoft has now fixed the bug that randomly disconnected users from the internet by breaking DHCP for some users around the world. However, KB3206632, released on Tuesday this week contained the following bug fix:
Addressed a service crash in CDPSVC that in some situations could lead to the machine not being able to acquire an IP address.
CDPSvc is the Connected Devices Platform Service.
To receive the update and fix the connectivity issue, you may need to first restart your PCs by selecting Start on the taskbar, clicking the Power button, and choosing Restart (not Shut down). Additional guidance can be found on the support forum here.”
Microsoft has updated its website to confirm KB3206632 is the patch you need to install to cure the networking connectivity issue, provided you follow the above steps.
