Good day fellow forumers. I am currently using c1200 provided by tm after successfully upgraded to 100mbps via free speed upgrade. The router I received is the router that get negative reviews from fellow forumers. I do agree. When i receive the router, it hangs after I use it. So a respected forumer, nikrizal, suggested me to upgrade the firmware using australian firmware. Once I upgrade, i realize it improves the performance of the router drastically. I am a heavy torrent user, when downloading, the router didn't freeze. In a day, 12 devices connect to the router and still the router performs the best. So the problem is on the Malaysian firmware programmed for unifi. This is my experience using c1200 so far.
