Unifi down for me (5Mps / Kepong area)... but I believe is due to the 'Modem' (the black one) To be more precise, when I turn on the Router + Modem, the Modem just blinks, the green lights. Turning on/off sees the variation of the blinking speed. I guess the Modem is toast. I never turn off my router + modem. It is on for months on end unless there is a power shortage like recently.

Called up TM and they said could be issue with the outside port since no signal is receive at my modem?! They will send someone to check on it but I believe my Huawei EchoLife HG850a is faulty (been using since 2012 with no issue). Some say changing the power adapter works, will try this in the meantime.

So my Huawei EchoLife HG850a stopped working. I came across a post that changing power adapter could resolve it. Tried with another 12V output adapter and bam... working again. I guess I should cancel my appointment with technician. So overheating issues etc. wasn't really the case when I first believed.

Haha... the thing is the appointment timing is always way off. I wonder if I can just mention to them regarding the adapter that resolved the issue and get a new adapter. Appointment made just to check the outside connection/port... and even that it on Friday.
