so i get this message when i try to use a cable to connect to the network. i can still connect wirelessly without a problem. i havent changed anything software wise, this problem has progressively gotten worse. when i get this message, i can sometimes wiggle the network cable and it will re-connect. sometimes i dont have to touch anything and it will re-connect (used to happen much more often than it does now, now it very rarely happens) and sometimes i wiggle it around and nothing happens. sometimes it seems like there is no relation between wiggling and connecting, other times it seems they are related. for now i am just connecting useing a wireless router, but what do you think could be wrong? is it software, hardware, and how do i fix it? thanks for your help.
