When I put the usb extention between the magicjack plus and the power adapter I noticed a white LED that is blinking behind the + symbol where the blue LED located. I see the blue LED lit, the white LED blinks every second same as the yellow/amber, but not at the same time.
I do know the green LED is the Lan link/act indicator.
not shure what the yellow/amber and the white LED is for
Thanks for pointing this out. Initially, I thought my blue light was blinking but upon closer inspection I also noticed a white light blinking next to the blue solid light when hooked up to my router. I'm guessing this is normal for everything seems to be working fine on my MJP.
