I have a single band Syrotech Ont using it since 3 years today in morning when I turned it on the lan lights didn’t glow up as a reason I can’t access internet from my computer even I can’t login my router but via Wi-Fi it works fine so I left in the morning as it is but when I came back in evening I saw the lan light glowing as a result I could access internet from my computer but just to check if everything is ok I did a speed test and then the light again gone. So can anyone tell me if my lan is faulty or any other thing.
