As bizarre as this sounds; as of yesterday, anytime i plug in my Newer Technology usb - dvi adaptor, I immediately lose my internet connection. As soon as I unplug it, I'm back online. Its worth noting that the extra monitor works fine when plugged in.
Prior to yesterday, this device has worked flawlessly for me since I purchased it about 4 months ago. I found one other example online of a user with this problem, but he was quickly shunned for not providing enough detail.
To avoid shunnishment:

Thanks in advance for any help, this is killing my productivity!
