My MRP issue has finally RESOLVED
Finally over!!! My connection issue has been resolved.
Yesterday, has a long chat with MRP and that they finally identified the backend problems which caused some new MRP customers unable to connect to their server since day one and was reported by OpenNet that their home wiring was certified.
They have since fixed their backend last evening and my ONT is now connected properly having an average of 830Mps when ping thru ASUS 56U router.
Yes, they don't reply to your email, tickets and finance dept still automatically dispatch nonsense email asking you to pay when things not working. And yes, CS don't know what you are talking about in most of the time...
Hopefully, I have contributed in some way to clear those teething problems at MRP backend so new customers will have a much better service in future.
Many thanks to some MRP people especially thread owner, Johnathan, Cedric and those tech guys who had visited my place (5 attempts in total).
