I've been plague by this HyppTV lagging issue since early December till now. Certain channels having the stuttering issue where the picture would freeze or lag in less than a second, however the audio is fine.

TM has tried increase bandwidth for HyppTV, failed.
Then I request for new TV box, also failed.

Even changed to Huawei WS880 router, too failed. I'm quite frustrated on this. Anyone else faced this and manage to solve this?

I've no idea. But I spoke to the technicians that came my house. They now change my Dir-850L into Archer C5 router and TM will monitor from their side.

Here's the interesting part, I went to restaurant and also saw the lagging issue on their TV. So I'm pretty sure it's TM side. Not our hardware.
