Picked up an ERL a few weeks ago and have noticed an audible hissing/noise attributed with load on the router. It will make a high pitched hiss and click like sounds (similar to a laptop hard drive), anyone elses do something similar? Guessing this is the DC power, but a little worried I might have a dud that could possibly go at anytime. I had an old netgear prosafe router YEARS ago that did something similar shorlty prior to failure. Just curious if others have noticed this as well..
Thanks!
