Actually it's now some months ago since I last used a VMWare WS Lab but I think I had the same or similar issue.
Open the *.vmx file of your vm and check what virtual Device type your network interfaces are:
Search for lines like this:
ethernet1.virtualDev = "vmxnet3"
When I add a new interface to the vm I get the following interface devicetype:
ethernet2.virtualDev = "e1000"
So if you now have all on e1000 try to change them to vmxnet3.
