I'm terrified to buy the s1, I was reading the set up and trouble shoot and now I'm worried I won't be able to set it up....
Very easy setup, I have purchased 4 units recently and just plug them into your network and most by default are set to 192.168.1.99 that I got and if not use a network scanning tool to find them and mine show up as Paragon Technolgies Inc. or Shenzen SHX Technologies Inc. as the vendor so they will be easy to find on your network if they are not that IP I mention.
For Windows you can user Angry IP Scanner or for OSX use Lan Scan Pro and you will be able to find them rather easily.
After you find them login with username/password which mine were all root for user and root for pass and then go into miner configuration and set your pools and worker names and your good to go, to overclock user Google and you will find the info.
Good luck!
