just got my 360 back and problems

and i put on my harddrive and it couldnt connect to live and i am pi$$ed

i plugged it into the back of the ethernaet port and it didnt work any suggestions

What was the error message? Any red rings? Exactly what steps did you go through to get to that problem?

so i plugged it into the waln and then i plugged it into the black router and it said my ip adress failed and it said that it wasnt connected KILLANINJADUCK

Do like I said and unplug your modem and router from the outlet they are pugged into for 30 seconds and then plug them back in and try to connect to live again.
