The 2nd and 3rd light turn blue (from green) to indicate DOCSIS 3.0 mode is enabled by the switch (hub) for which the modem has an internet connection. The lights remain green if your ISP only supports DOCSIS 2.0. The 1st and 4th light appear to be a whitish hue, but in fact are a very light green. This is known as light abberation and is caused by the close proximity of the different colored LED lights. If there were a physical separator between the LEDs, this abberation would not occur. In this particular case, the blue LEDs are so bright, they wash out the green color of the green LEDs and as a result, they appear to be white.
D J I know this is an old comment, but mine cycles through the blinking LED's and the green are bright green, totally different than this whitish green I now have. Trying to figure out how to connect it to my wifi
September 2022 and you just described and showed my exact scenario with my newly purchased same model. Thank you @PC Gamer for your response to the question.
I have the SB6190 black and my power light has always been light green and the next 3 blink light green till they all go solid light green and then the rcv light just below the power light goes to bright blue then after about a minute the send light goes sold bright blue and the ethernet to the Wi-Fi router stays light green and the router internet light changes from yellow to green to indicate the modem is passing internet to the router. What I am getting now since an outage in my area is the send light stays light green and not bright blue! So I guess it is an indication that I am not getting 3.0.
They're are correct, they are Blue, because your router is capable of pushing out a gigabit connection. Meaning you're getting the fastest speed available, if you're router cannot handle that much speed, it'll be green.
same here, seems to be working fine 50/5 speeds, just no visable power or inernet lights from the outside, can see them looking thru the vents dim lit green... guess the blue just over powers it....
that's not a problem its the inside LED light they used its cheaply made I guess to same cash but that's how its suppose to be I have 1 my self and its the same thing
Unplug everything from the modem. Leave unplugged for 5 minutes!!!!! Plug everything back in. (Now it should work) I did this, now everything's back to working.
This just happened to me 2019....shit always goes wrong with my shit...ffs. Seems to be working fine tho so I dunno...and everyone else says there's works fine too.
