I like using wired Internet connectivity in my apartment because of the extra security -- but man, is it frustrating sometimes. My 2013 Macbook Air requires me to us an ethernet-to-USB adapter which sometimes works flawlessly and on other occasions just refuses to send data (even though it's getting consistent power). It may be running fine one moment and then suddenly stop sending/receiving, at which point, bending or otherwise playing with the Ethernet and/or adapter cord usually gets it going again. For a while. Unless I'm fooling myself and the restoration is just a coincidence. I've swapped out adapters, I've swapped out Ethernet cables, I've even switched from one USB port to the other. Same behavior. Do these things just suck, or is some other link in the chain failing on me? I'm sending the signals through a TRENDnet router that apparently has no trouble feeding data to/from other components. UPDATE: Getting the same problem when connected to Chromebook, so's definitely not my Mac.
