Hi. Ive just got my router and it didnt come with a power adapter. Its a V1.1 GS model. Ive done some research and it works from 3.5v upto 18v. And it can take 5v @ 2a (10w) or 12v @ 1a (12w). I plugged in my 7.5v 500mA (3.75 watts only) adapter and it works... But Im worried I may be damaging the board or reducing its life by not giving enough watts. Can someone clarify if my statements are incorrect and whether it is safe or whether I need a new adapter? Thanks, Ryan.
