Hi, I recently bought a new macbook pro 15" retina display. I purchased a USB to ethernet adapter however I cannot seem to get any internet connection through it. It says the ethernet port is active however it does not seem to be picking up an internet connection. I have only just converted to OSX from windows so I am not very knowledgeable with networking and macs. Is it possible that I have to configure my router? note: the wireless signal from the same router works and connects to the internet.. Thanks for your help in advance.. Namaste!
