As long as your computer and the cube are on the same subnet they should be able to talk to each other without a router interfering.  If your ethernet card is old or just crappy you might need to plug both into a switch / hub instead.  With them directly connected and your computer IP set as 192.168.1.13 you should be able to point your browser to 192.168.1.254:8000 (or whatever is printed on the cube).  You might need to change your gateway to 192.168.1.254, but I'm not sure of that.

If that address doesn't work then it's possible the previous owner changed the cube's IP address.  A common IP is 192.168.1.200:8000, so try that.  Is there some sort of factory reset on the cube at all?  If not, then you can use nmap on windows http://nmap.org/zenmap/ to find its IP.

If your router supports a separate VLAN then you can setup a second subnet that way.

Everyone's hit everything, so I'll just add that the transaction ID is public knowledge, so you can't really use that as any kind of proof.

Plug your computer's ethernet directly into the cube.

I also don't understand why you can't change your router's IP.  You can always try resetting it, as you might not know the administrator password.  It'll go back to whatever's written on the router.

If you choose to store it online (a terrible idea) then at least have 2-factor enabled on your google account.

I guess we should ask how many BTC are you storing?  If you can't afford to buy a printer or a two pack of USB drives from Costco for $20 then it's probably only dust.  In which case it doesn't really matter.  If you're storing thousands of dollars in BTC and are worried about saving $100 then you're all messed up.

Can you explain a little of how the exchange works?  If I want to buy 1 BTC do I buy it from your coins or do you match me up with someone who simultaneously wants to sell 1 BTC?  Does the seller send directly from their wallet to my wallet, or does it go through your mixed coin wallet?

Buy one USB miner for like $30 and buy 1 BTC with the rest.

Fairy tales aren't theories.

Each block contains a link to the previous block.

Why is your go to explanation for everything you like god did it and everything you hate satan did it?  Don't you see that's just silly?

Science is based on facts, not what you wish to be true.  Science doesn't discard facts because they make the world "Seem a bit hopeless".  Can you imagine where we'd be if they did? 

What if the user sends a bet, it's a loser, and so they send another mutated bet, giving them another chance to win with the same coins.

We've been trying to tell you, but you won't listen.  It doesn't exist.  Just use any mixer and divy your coins up into separate addresses to send from.

Maybe you'd be better off with the piper paper wallet printer.

The paper backup is all you need.  To keep armory installed you should use a persistent image or install to a flash drive.

You can use electrum's APIs as a backup.  Or you could just use electrum.

You admit that you don't understand this video, yet you believe it?  It must be terrifying going through life without any critical thinking skills.  How can you be content that you can't reason whether a fairy tail is true or whether science is true?  Why don't you try to learn anything?  I just don't get it.  Do you think Miller Light tastes great and is less filling?  Have you bought a timeshare?  How do you function in life without being able to process information correctly?

Thanks for clearing that up, I left you a large tip.

It's a wallet.  Source code has been forked.  Look at the forum you're in.

You can use bitcoind sendtoaddress.

You might have to wait until it syncs anyway to use listunspent.

Oh that is simple, there are a lot of services like that.
