Hi,

What are the docks connected to?

I ask as the ethernet on the dock supports auto negotiation and full duplex. You can't fix the speed or connect it to a half duplex connection (such as a 10/100 Hub).

Thanks,
James

you mean the switch?
I'm not familiar with the exact model, but it would be a HP Layer 2-3 Gigabit switch.

When plugging my computer in (Fuji T732) I get good Gigabit speeds (80+ MB/sec)

External Monitor performance has also not improved.

There is still stutter/micro-stutter when moving over hyperlinks which DOES lead to misclicks and gets very annoying.

As per my previous post, network performance is at best, the same as previously if not worse. It does seems link a USB2 connection, not a USB3 connection.

Are these issues still being looked into, or have you marked them as 'solved'?

I work in education, we have started rolling these units out instead of model specific docking stations, and still have a large amount to do, this is not very promising.

Can you see if the lag is solved by the test build in this thread:

It certainly addresses a known issue with mouse lag.

The Ethernet throughput should be faster than you are seeing. Do you have any software firewalls installed?

There is a firmware update for the USB 3.0 hub in the dock. Updating this might help the USB 3.0 throughput. Also updating the Intel USB 3.0 host controller driver in your PC might help.

Updated the USB3 host driver recently, I believe it's still the latest version but will double check.

How do I go about the firmware update?
