First of all, i would like to Thanks @yeapch01 for his great support. Highly recommended

I applied Time Fibre around 1month+ ago. Few issues i experienced :
1. After the line was installed, it worked for the first day, then totally no more connection after that for the upcoming few days until i called them and they sent the same technician over to fix the issue.
2. The day after they installed the Time's line, my Unifi started acting weirdly. I had to call Unifi technician to come over to have a look. Found out (high chance) Unifi's issue was caused by the Time's technician when the Time technician installing the line (the Unifi wires in the hub / switch, part of the wires messed up, causing my Unifi line to have weaker signal, this made it dced in game very often and the speed has down from 50megs to be 12-14megs, which i never encountered such issue with Unifi for so many years)
3. The download speed and upload speed aren't max. 500megs line but i have only max 420+- download and 490+ upload (using LAN cable, tested a few days, every time has similar result, download speed never go over 440+ and upload speed always around 490+). I have been using Unifi for many years in difference locations / houses, always able to get full speed when doing speed testing, so a bit disappointed on Time for this part

4. Upgraded to 1gig line last month, website showing upgraded successfully and showing i am using 1gig package now, but the speed has no changes, still download 420+- and upload 490+-. I contacted Time support, they said will send someone to call me to check, almost 3 weeks passed but i never received any call from their technician and no update via sms or email.
5. Yesterday when i reached home, found out Time's line is dead, LOS button is red. Until this morning it is still not usable. (atm talking with the support now, asking me to turn off / unplug replug, restart, which i had done a few times yesterday)
I will continue to use Unifi (just as a backup in case Time is down, i will monitor Time's performance for 2 years before i decide to cut Unifi) and will continue to support Time, but i hope Time can improve their services and expanding their coverage to more area (which my friend needed it badly, he stuck at Unifi 30megs package)
