Problem
When starting LR all network activity on my WiFi connection stops (as observed in the "Performance" tab of the Task manager) and I can no longer access anything from the web (websites through a browser, LR Mobile in LR, Skype etc).
How can I fix this, or further diagnose what is ging on?
Symptoms
After a short while the WiFi will be shown as having No Internet
in the taskbar network overview.
Connectivity can intermittently resume while LR is running for short periods of time, but only resumes as normal once LR is closed (including the diagnostic report showing that all is fine). This does not seem to happen with other Adobe Creative Cloud applications.
Additional Diagnostics

Windows Network Diagnostics
The WND indicates that Windows Sockets registry entries required for network connectivity are missing
, but the issue cannot automatically be resolved.
