Your chances of any return whatsoever with a pool that's just you are essentially non-existent.
Pool mining works since pools can accumulate a large amount of hashpower from thousands of users. The pool's chance of finding a block is then fairly high, which then allows them to use the block reward to pay proportional amounts to all their users.
I found the problem. In fact, although the PING to Antpool.com was successful; however, the network used a proxy causing problem of connecting successfully to Antpool.com. So, after changing the network I could see the hash rate in my dashboard.
The main hardware difference is, the hash board heat sinks are different heights! You cannot use all 3 S9i hash boards in a regular S9. The S9i heat sinks are 3mm smaller on the bigger heat sink side(silver) and the smaller brown heat sinks on the other side are 3mm taller. You can only fit 2 S9i hash boards in a S9 housing.
