My connection is 40mb fiber optic.
Creating a conf as you said i got 1 block now, but I believe that something in the code can be improved on next wallet.
No orphans with crave or graviton
It's hard to know if something is wrong without knowing how many you are trying to stake.
Try to dumpprivkey for the address/es you are staking with then import those keys into a fresh wallet with importprivkey. Stake with the new wallet.
Also, it really helps to open the port on your router if you can because it allows you the most number of peers to broadcast your blocks to. For graph the port is 30371.
One of the things I like to do, and this requires a little bit of effort, is make a second wallet on another computer with server=1 and add that node to your staking wallet. This allows you to broadcast to the network a little faster. I think people are figuring this one out, and that's why you're seeing a lot of orphaned blocks.
You can even do this on the same computer, I'm not sure how it's done on Windows but I'm sure it's simple. With Linux, you simply spawn another daemon process with ./graphd -datadir=/home/coin/.graph -daemon and make sure you change the rpcport in the coin.conf and addnode=firstwallet as your node.
