Got home today and noticed my wifi was down. Checked my AirPort Extreme and noticed it was flashing amber. Plugged my Ethernet cable directly into my computer from my router and it works fine, but when I try running an Ethernet cable from my AirPort Extreme, nothing. I open airport utility and it can not find anything. I've gone as far as to try to do a hard reset, but it just continues blinking amber. Have unplugged and replugged the power numerous times to no avail. What do i need to do here? It's worked flawless up until this point.
