Hello i am trying to get a really good deal sorted. 1 ac66u b1 and 1 ac66u for 20 bucks. b1 is missing power supply and ac66u is missing an antenna. I currently have a spare n66u which has a 1.58A power supply. But the b1 is demanding 1.75A power supply, is it possible to run the b1 on a weaker supply or is the plug different? The b1 will be used as a aimesh router. If i disable as much unnecessary sh*t as possible on the b1, will it draw much more than 1.58a?
