as you can see in the bill, the charge will be rm 179 - 70 per month for your unifi turbo 300mbps (rm 109) + rm 30 for hypptv..
so rm 139

From my experience migrating from old unifi 100mbps to new unifi 100mbps..
I go to TM Point Tanah Merah, Kelantan...
Go at 3 pm and no queue since it is small city.. (btw my unifi is in kuala terengganu)
Talk nicely to the staff but when she have problem when changing my plan, she instantly call Kota Bharu branch asking for help and said it is urgent so i did not need to come again for this..
10 minutes in there for thumb print and all the process..
Back home, after 1hour++, the plan change in unifi portal already..

My advice, just talk to them nicely and they will treat you nicely too..
Do not make the process hard for them..

have u check what is the speed for your ethernet network? refer picture



also try with another ethernet cable.. probably faulty cable you have there..

is the router is new too?
but if in network status it showed 1Gbps, i think the problem is with that cable.
try with free cable that TM give you, they ussually give cat5e cable and see if that make a difference.

i have extra stb box.. if u want i can sell u rm 100... cincai la
