I have a Ruckus 7372. Can't seem to get it to turn on using any AC adapters I have. The label on the back says 12V-1A... Well, 12V-1A doesn't work, 12V-1.6A doesn't work... does it need something beefier? I have a 12V-20A bench supply that it does work with. Just confused since the label on it says 1A and it definitely seems to need more.
