How to find out the cause of the loss of connection between the two MacBooks?

Two MacBook, between the Time Capsule as a router. In the first MacBook Shared access to the folder X. the Second MacBook is connected to this folder via smb using an account from the first MacBook. Second laptop shakes data from the first. A lot of small and large files on 100GB.

All good for the first 10-20 minutes, but then the process stops. Open Finder, select the Network, the first computer, the folder, and nothing happens. Finder blank and "Connecting..." in the status bar. And stand so maybe half an hour, no errors, nothing like that. Press the retrieve icon or the Disable button - silence. Nothing disabled, just silence. All just hanging out. Helps only reboot. After restarting again all the rules and can continue to work.

Do you think where is the problem? Times it helps to restart the computer (the second of course), it is unlikely that the problem with the first laptop, and it is unlikely the router. So something with the second, but I don't understand.

View logs in the console during execution, and problems.
There are so many logs and so much strange that I do not know where to look or what it all means. In snatches of text, too, to mind nothing comes. :( - madonna52 commented on April 3rd 20 at 18:44

Because, as you know, all MacBooks equipped with an Ethernet port. - Christy commented on April 3rd 20 at 18:52
