Currently I'm using this "Gigabit-Fiber" and the speed I subscribe is 100Mbps. So far I use the speed is stable on morning or night same. But the large problem is their server site communicate to other web services. For example I'm playing ubisoft game and sometime I couldn't launch success of the launcher by using their services so that I need use vpn to by pass their server to ubisoft service. And right now EA launcher same as what I mention, can launch but no service. The next problem I not sure is my modem place problem or their problem cause sometime whatever I doing playing games, browsing.. the internet will suddenly disappear and will reconnect back in 3 minutes, but when I playing games this couldn't be allow though. Last problem I also not sure is my problem or their problem.. My house are using TVbox to watch drama which 三立, not sure is the tv box server problem or ISP problem cause my family only watch few channel every weekend and weekday and only one channel not able to view. But first, I tried use simcard to sim modem and share LAN to tv box, the channel was able to watch.
