Hi,
Like to share my migration experience from MyRepublic Pure 100 Mbps to Ultra 1Gbps which was carried out on Mon, 28 Apr 2014.
Since my 2-year contract was coming to an end, I signed for the upgrade in Jan 2014. Just 3 weeks ago, I received a call that my upgrade installation was scheduled on 28 Apr, between 0900 and 1300 hrs. In order to keep disruption to the internet access at the minimum, I initially requested for the installation to be carried out on weekends but after hearing that the internet access may be disrupted on Friday, I decided to stick to the original schedule.
On the day itself, I was still able to access the internet in the morning. Around 1130 hrs, a MR technician called to inform that he was on his way. After reading how things can go wrong, I actually asked him whether he has checked with OpenNet on whether they need to do any switching, top-up or whatever. Was relieved when told that since I am just doing migration, OpenNet is not required. Strangely, a few minutes after his call, the link LED on the Nucleus Connect ONT turned 'red' and no more internet access.
After the technician arrived, he replaced the NC ONT with the black Alcatel Lucent ONT Model I-010G-U (did not subscribe for voice) and proceeded to initialize the new AL ONT. Except for some minor hiccups on the technician's laptop to access the internet, the new AL ONT was good to go. Was able to achieve 840+ Mbps download and 450+ Mbps upload when my laptop was connected with Cat-6 cable directly to the ONT using speedtest from speedtest.net and MR. However, when the existing EnGenius esr9850 router was re-connected, can only hit 130+ Mbps download and 140+ Mbps upload. Suspecting the router was capping the speed, decided to leave it as I need to access the internet urgently.
This afternoon, after 3 days, I managed to replace the existing router with the paid ASUS RT-AC68U router that came with the upgrade. During the setup process, was prompted to update the firmware which showed 5571. With the new router, speedtests are now showing between 850+ and 940+ Mbps download, and 450+ Mbps upload. As of this evening, both the new AL ONT and ASUS router are behaving ok.
