I tried unplugging my modem/router thing for 30 seconds and 5 minutes. I was also told 8 hours, but that seems extreme. My IP recently changed for some reason and the new IP I have is already banned from a website I go on very often(wasn't me), so I really need it to change. Getting very frustrated and don't know how to change it. I have a MAC computer and its hardwired into the wall, so any ideas?
