Try another computer or reset your iOS device. Just like we said above, some third-party software on your PC or Mac could prevent iTunes from connecting the servers. If you do not know what kind of software is putting a spoke in a wheel, try to restore, sync or backup your iPhone from another computer. If the problem still appears, the root may be hidden inside the software of your iOS device. In such case perform a hard reset or restore your iPad or whatever iOS gadget you have. This will take some time and you will lose your data, but you will be able to start from the scratch and eliminate everything that cripples connection with Apple’s servers. Alternatively, you can manually download IPSW file and update or restore it without the need to download firmware inside the iTunes.

The sad thing is that sometimes Unknown Error 1671 is not related to the network at all. In some cases, it may show up if there is something wrong with your USB-connection. Disconnect your iOS device from USB-hub or front panel of your PC and connect the cable directly to the motherboard USB. If you are using MacBook, plug in a cable to another USB slot.
