The setup includes a Technicolor modem and a D-Link AC router plus three Daimai TV boxes.
The Daimai TV boxes are very slow to boot. For those boxes not close to the router, they receive Internet via Powerline adapters. There is frequent "buffering" when watching TV except for the box connected directly to their D-Link router. When not buffering the image doesn't exactly look HD to me, but it's better than SD. There are a lot of channels.
For one of the TVs, the installer connected my in-law's existing Asus RT-N66U to a Powerline adapter, and then a Daimai TV box to the Asus router. He left the cable running across the carpet instead of even trying to conceal it. So now a weak Powerline signal is fed into a redundant wireless router (SunTel's D-Link router is also broadcasting a Wi-Fi signal) which then splits a very weak signal to the TV box? No wonder it's always buffering! Not sure why they would do that.
The D-Link Wi-Fi signal is weak. It cannot reach the basement on the opposite side of the house. However, the Asus RT-N66U can reach it, albeit not with a super strong signal.
I actually didn't get a chance to see how the phone is set up. Their phone service is just terrible. There is constant echo and background hiss. That's when it doesn't cut off entirely. More than a few times I have found myself talking to myself and then saying, "Hello? Hello?" as my in-law's line has suddenly disconnected without any warning! Completely unreliable!
Pros: You save a lot of money.
Cons: You get what you pay for.
With such shoddy installation work and quality, I'm not sure I would be comfortable paying these guys 2 years prepaid!
