I've an Airport Ext.Base,802.11n with NO visible power light. However, small green lights blinking on the rear of device. Have removed and replaced power cord several times. Checked to be sure power is present at wall plug. Haven't check power at the round tip of the power cord and not sure what would be the correct voltage. Is my WiFi Base deceased?
I'm getting just over 24 volts when measured at the power cords round tip plug. Is it possible the unit requires 24v and not 12v?
Check to see if the outboard power supply "brick" will deliver a steady 12 volts. If it doesn't, then the issue may be the outboard power supply. It might be a $20 risk to find out though, if the seller will not agree to issue a refund if you want to return the part.
If a new outboard power supply does not do the trick, then there is an internal power issue on the AirPort Extreme. Since Apple does not offer repair parts, and it would cost far more to rob another used AirPort for parts, the AirPort Extreme should be replaced.
You don't indicate which model number of AirPort Extreme that you have, but the average useful life of the AirPort is about 4-5 years.
After reading the specs on the ebay unit, I see 12v is correct. I may well have a bad "brick". Thanks
Airport Extreme , no power light
