I have since moved the Ethernet connection direct to the router in the basement rather than the switch. My office upstairs was still having dropped connections. I have since reconnected a second router in my desk upstairs to prevent drops.

Drops
WAN -> Router (basement) -> Dock (upstairs)
WAN -> Router (basement) -> switch (basement) -> Dock (upstairs)

Works
WAN -> Router (basement) -> Router (upstairs) Dock (upstairs)
WAN -> Router (basement) -> switch (basement) -> Router (upstairs) -> Dock (upstairs)

It seems like the router upstairs is acting like a repeater and preventing the link drops (and negotiation issues), but this all started around the beginning of this thread, it still works with other usb or internal Ethernet adapters, and the router seems not to drop connections to the downstairs links even with the same wires.

Router downstairs is cisco E3000 Router upstairs is TP Link Archer C9 and switch downstairs is Trendnet Greennet 8 port all gigabit
