How can I use wired ethernet + external monitor together on my Macbook Air (Late 2013)? I have a late 2013 MBA which only has USB 3 ports and one Thunderbolt port. I've currently been using a Thunderbolt to Ethernet adapter to use wired internet, but I'd also like to use an external monitor at the same time. Are there any USB to HDMI or USB to Ethernet (provided that the internet speed won't be decreased) adapters which I could use?

Thanks
Apple sells an USB Ethernet adapter. But since it's USB 2 it's likely to speed down the network capabilities. 

There are other adapters with USB3 which seems to be faster (and compatible with OSX) .
