Also that way you synced and verified the blockchain yourself and not trusting the RaspiBlitz FTP/Torrent downloads (dont trust, verify).

Once you finished all the transferes the Raspiblitz will make a quick-check on the data - but that will not guarantee that everything in detail was OK with the transfere. Check further FAQ answeres if you get stuck or see a final sync with a value below 90%.
## Why is taking my torrent download of the blockchain so long?
Its a lot of data and torrent seeds can not be garantuued. Normally it should be done within 24 hours. If it takes longer then 2 days consider to abort the torrent download by pressing 'x' and choose FTP download as fallback ... will also take some time, but should be more stable. If even that is not working - choose SYNC option, which will take over a week, but is the classic way to get the blockchain thru the bitcoin peer2peer network.
**If you want to replace a corrupted blockchain this way:** *Go to terminal. `sudo systemctl stop bitcoind` and `sudo systemctl stop lnd` then call `/home/admin/50copyHDD.sh` use the displayed SCP commands to copy over the fresh blockchain but in the end (when copy is done) use the CTRL-C to stop script and make a reboot with `sudo shutdown -r now`.*

- Setup a fresh RaspiBlitz
- Stop LND with `sudo systemctl stop lnd`
- Replace the new `/mnt/hdd/lnd` with your backuped version
- Make sure everything in `/mnt/hdd/lnd` is owned by bitcoin:bitcoin
- Reboot the RaspiBlitz
This is highly experimental. And again: If you restore the LND with an backup that is not representing the latest channel state, this will trigger the lightning "penalty" mechanism - allowing your channel counter part to grab all the funds from a channel. Its a measure of last resort. But if its working for you, let us know.

You dont need a LAN port on your laptop as long as you can connect over WLAN to the same LAN router/switch the RaspiBlitz is connected to .. and you are on the same local network.
## Is it possible to connect the Blitz over Wifi instead of using a LAN cable?
A LAN cable is recommended because it reduces a possible source of error on the network connection side. But how to setup WLAN when you dont have a LAN-Router/Switch available see here:
