Router Problems

[Sonicnine1]

We have it wired to our power distribution board through the 12V to 5V inverter, going to some cables we used last year. A team that was in it longer, Team 360, helped us wire our D-Link, I think the power is fine. Let me explain the issue again. Our D-Link works fine, until we hit a bump (a crease in the carpet) or accidentally ramming it into a wall (like a robot hitting us in the competition). Then we lose connection to the robot and the router from the field control system. The power light turns red on the D-Link router, which it does anytime we plug it in (it turns blue later, Im assuming that red means it is starting up). We do not want to have this problem in the competition (we had it last year, we couldn't play after our robot was hit until the next match). Any idea why it is doing this and how we can fix it by the competition?
