7.3 M0 performance

[mekul]

Since installing version 7.3 a couple of days ago, now my network connectivity has gone down the drain. My computer loses connection about 10 times per hour to the point that it is almost unusable.
This is definitely the dock, as I can disconnect and use my wifi without issue, as well as 6 other computers on the network all operating fine.
Is anyone else seeing this issue? Network connectivity has never been strong on this dock anyway, but now its 10x worse.

Setup:
Toshiba Dynadock USB3
7.3M0 drivers
Samsung series 9, Win 8 x64

Any ideas on what I can try? I uninstalled the old drivers before installing 7.3
