How to Fix a Broken Network Cable

i spent a good bit of time at my currant largest individual contract. And we had a problem for a while. A very valuable, very important employees' network stack just kept dying on her laptop. So i went back to the wall where her laptop was plugged by way of like a 25 foot ethernet cable into the wall jack. I thought maybe the tab has been crushed on the cable and the cable will just pop out without having old the tab in,. But instead, what happened is the whole frikin wall jack, the keystone, just came out, still attached to the cable.
