I was having trouble with UNIFI for the past 1 week.

Unifi guys are generally very helpful, even to the extent of remotely settle your issues, but it wasn't settled.

So they called yesterday to send me a technician to troubleshoot this morning.

They changed my modem, it's exactly the same model, but I didn't get any disconnection or jam after that!

Had been monitor for the past 7.5 hours, so far so good.

I even showed the technician my TP LINK WR841ND that I bought jUST before they called. He said, "keep this, you might need it if the dlink is down, its generally better than what TM offers"

So, now, I'm still a happy user, albeit sometimes the speed will slow down to 1.5 mbps at night.
