Hi guys,

I setup a network of routers and sometime (1-2 times every day) the network is failing. Sometime you cannot access nothing, sometime I am getting IP 0.0.0.0 on my phone's network connection. See attached the diagram of the network.
Oh, the connection is ADSL, ISP Dynamic IP, main router is a Movistar Peru (Askey), routers 2 and 3 TP Link 801ND, router Floor5 is a D-Link (kind of old version).
Sometime I add a Switch in between Switch 1 and Floor5 router. Same story. Working some time, then it freezes.

Thanks,
