Thanks for all the replies! A WiFi AP is on the list.
I ordered a Ledger Wallet Nano. I plan on joining a pool so how does the Bitcoin get from the pool to the usb wallet?
I would not use the Ledger Wallet for your mining transactions, you will find after a while that it get's very slow, this from their help.
It is not recommended to receive small payments (also called dust payments) on the Ledger Wallet. This kind of incoming payments are typical of mining pools or faucets.
Set the payment threshold at a higher level (for instance 0.05 BTC), or use an temporary wallet which you'll empty every 0.05 BTC.
The reason is that the chip must sign all inputs when you want to make an outgoing transaction. Imagine that you have received 1,000 payments of 0.001 BTC. If you want to make a payment of 1 BTC then the chip will have to construct a transaction of 1,000 inputs and sign 1,000 times. Not only it will take a few hours, but you have risks that it will not manage to do it (the chip may get too hot and fault some computation etc).
I used one initially but then opened a Coinbase account as another problem with the Ledger Wallet is that you cannot Sign a Message. By all means use it for long term storage, but I would sign up to another account for mining.
