internet keeps going out

I just got my MoCA adapters and hooked them up as instructed in the thread with the pictures.



All is working well, as in, internet comes on, Tivo minis are connected.



There is just one SMALL problem.



The internet has disconnected about 7 times in 3 hours. It just keeps going out and rebooting and then coming back on.



This is not going to work long term at all.



What might be the issue?



Thanks,



Dawn
