Hello;
I am using the Calibre EBook library on my PC and Calibre Companion for Android on my tablet to read the books. I can connect to Calibre using CC without a problem, can list the books available and can select the book that I want to download. The problem that I am having is that it seems to take forever to download a book. I mean it takes several minutes at least to download a simple pdf. I don't see it as a network problem as I can transfer files back and forth without a problem. Does anyone have any idea as to possible sources of the problem? Any insight at all would be greatly appreciated.
Regards;
Frank
