Thank you for contacting Plugable support, we’re here to help.
I’m sorry to hear about the issue you’re seeing and I’d like to help. I’m not sure if you have already tried this, but are you able to plug in a different computer using the same network cable and into the same network port on the wall?
If you’re still seeing this issue, I’d like to work with you directly and have you run our PlugDebug tool so we can gather more information about your setup to help us understand what the issue may be. Please plug the device into your computer, then go to this page and follow the instructions there: http://plugable.com/support/plugdebug
Please do not post the log files here, instead please e-mail them to email@example.com and include ticket#283491 in the subject line please.
