When I purchased my latest Macbook Pro many months ago, I wasn’t happy that it had no Ethernet port. Sometimes, you just need to get the speed a network cable provides. So, if you have a Macbook Pro or Macbook Air that doesn’t have an Ethernet port BUT you have a USB port, consider doing what I did. I purchased an iLuv USB Ethernet Adapter. I got the one with two USB ports built in so I wouldn’t lose out on USB options. Here is the one I purchased (not an affiliate link – I make nothing off directing you to their site). They have other products but I haven’t tried them. I am, however, very pleased with this adapter. It allows me to wire up when needed (like my room at work that doesn’t get good WiFi) and the quality of the product is very good. I highly recommend it.
