It would be difficult to do in a safe way as your private key is needed to mine a block. The simplest way to increase regularity is to
buy more BLK. 
Mine hasnt staked for weeks but its a really iffy wifi connection thanks to big old house walls. Does it matter much if it reconnects a few times a day, not sure if connectivity or bandwidth would effect it That node stuff should go in code tags (or any big quote tbh) btw, less spammy
