I found out this problem on Friday evening when I couldn't install drivers downloaded from Nvidia website. I thought it was my PC (since it was newly installed) until I tried to use other computer in the house. After few frustrating hours, I downloaded the drivers using my Celcom broadband and they seem to be okay. That was when I being a smart alec and recycle power to the BTU .. and after that, I couldn't get connected to the net at all .. my voip and iptv also gone too. Grrr..  TM tech. came to my house today without fixing an appointment and I was doing my raya shopping .. there must be some stupid people at their backend trying to do some funny stuff.. I'll surely will claim a rebate on the days my Unifi is down.. got their direct contact already .. tm staffs should hide their identity when replying to the customers but they started cc-ing to all in the department and not removing my email from the distribution.. haha..
