It's a Netgear.  It's total garbage, not even acceptable for noncritical
home use.  It needs discarding.  Get a proper switch.

There ARE switches for which autonegotiation will work properly.  Do not
expect autonegotiation to work properly on any consumer switches, though.

There are too many things that go wrong with computer systems to spend your
life _also_ debugging flaky network hardware too.

The FS116 isn't even reliable enough to use as a doorstop.
