Intel optimizes IPv6 networking into nothingness, say users
Users are reporting that Intel's Connectivity Performance Suite (ICPS) is causing significant IPv6 networking issues on various laptops, including Samsung Galaxy Books. The software appears to interfere with network packets, leading to connection errors in applications like OneDrive and OneNote.
Why it matters
This highlights a common issue where proprietary 'optimization' software can degrade system performance and connectivity, frustrating end-users.
Customers report connectivity strangeness in the Intel Connectivity Performance Suite
If you're encountering some odd IPv6 networking issues, the culprit might be the Intel Connectivity Performance Suite (ICPS), although the chipmaker has kept quiet about the problem.
A Samsung Galaxy Book owner contacted The Register about some decidedly odd networking behavior that they eventually traced to unwanted ICPS optimizations. And by "optimization", we mean "borked networking."
For our reader, the problem showed up in OneDrive and OneNote. Notebooks were showing as empty, even though they were reported as "Up to date" according to the software. Microsoft couldn't get to the bottom of it.
A bit of sleuthing by our reader revealed that something was borking the IPv6 packet. Removing Samsung's ICPS build (40.25.926.0) and installing the generic release (50.26.623.243) fixed the problem.
