Right. A newer Ethernet chipset may have a driver that is not as mature as an older, more proven driver. You can try to open device manager, right click on your Ethernet adapter to display the properties and click the driver tab. At that point, there is a update driver button. This is all from memory so I hope the instructions are accurate.

Did you restore to a checkpoint after the 32 bit Cisco client didn't work out? It's possible that remnants of the Dne driver or it's bindings are still present on your computer which may cause issues with other intermediate drivers.

The 2.1.7 version was the first to include the improved driver set. We did an immense amount of work to improve these drivers so that issues like this would be much less likely. I'm not claiming that that our drivers are perfect ( no software is ), but they are very stable.

What Ethernet chipset does your pc use and what driver version do you have installed?
