I got my LA6M today but only one of the controllers is functional

. The other controller isn't recognized by my router. This means I can only run 10 units right now (only half of my order). I tried all 20 on one controller but it wont use all the miners and only gets 3mh total. Not happy with this situation. Is the lightningAsic brand the only controller that disables sha-256? I need a controller (that disables sha-256 and only mines scrypt) fast.
