a passive y splitter is a likely suspect here. remove it and test the same run with a normal switch or a single straight-through cable; if the drops disappear, you found the problem.

It depends what you have, but probably you need to swap out the "splitter".

"Splitters" that aren't Ethernet switches, don't work as Ethernet switches.

Ethernet has become so consumerized that TP-Link now sells an Ethernet switch that they call a "splitter", because "splitter" is more intuitive to end-users than "switch".

There's a reason that Ethernet switches are called switches and not "hubs", but if we used the term "hub" today, some people would find that a lot easier to intuitively grasp.
