I am afraid that this is one that might not have a solution.

When CC connects to calibre, it (like the vast majority of network programs) creates what might be thought of as a "pipe" between the two programs. The information exchanged goes through that pipe. When your device disconnects from wifi, even if only for a few seconds, the pipe is broken. Information can no longer flow. The only way to recover is to construct a new pipe, something that is very complicated to do given that "things" are half-done. This is something that neither calibre nor CC are prepared to do.

There are some actions that might help.

1) Determine why your device is disconnecting. This absolutely should not be happening and will cause you grief in the future. Some reasons I can think of for spontaneous disconnects are:
- The device is too far away from the wifi hub.
- (The most likely reason) There are too many neighbor wifi hubs using the same wifi channels as yours. Use some wifi site survey software to look at which hubs are using which channels, and of possible pick the least-full channel for your hub.
- You are using a high-bandwidth wifi protocol (g or n), and either the device or the hub is buggy. Try limiting the speed to b. Another advantage of limiting the speed to b: it uses a narrow channel, limiting collision opportunities.
- You have a cordless phone or a microwave oven near your wifi hub or device. Both of these use the same radio channels as wifi (2.4 GHz).
- Your device has bluetooth turned on and it is interfering with wifi.

2) My guess is that you are using CC's scan books feature, and further that the books are not all epubs. CC can extract metadata from epubs, but depends on calibre to do it for all other book formats. If I am correct, it might be faster to resend the books instead of scanning and sending the books to calibre for analysis. Each book received by CC is a separate "transaction", so any received before the network dies will remain.

If you cannot make progress, we can give you a refund. Send email from CC's help dialog. Be sure that you use the same email address that was used to purchase CC, provide the date of purchase, and if possible the Google Play transaction ID.
