WNR2000v5 won't connect to wifi or through Ethernet

Ok so a few days ago my router was unplugged by accident while moving my PC around and now that everything is back where it was the routers wifi and Ethernet cannot connect. Everything is connected the exact same way as it was before and it was working but now I am having problems. The Ethernet through the router won't even shoe up on my PC or the other one in the home, and the wifi can be seen my my mobile device but when I try to connect it gets stuck on obtaining up address. I have contacted my ISP and everything for our modem is working and I can connect to that wifi but the wifi and Ethernet i used to get through this router will not work. All of the lights appear green when the router Is on as well. I have not had any updates or anything so all software is the same as before when it was all working
