They stopped on node1

"
traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 60 byte packets
 1  10.190.241.1  0.470 ms  0.310 ms  0.387 ms
 2  10.190.241.1  0.287 ms  0.294 ms  0.287 ms
"
that's it. 
The raspberry pi is plugged to the network with wire.

When i work from my laptop (which is connected with wireless interface)

About internal network scanning
Now it s ok. I reloaded all routers and raspberries pi
I've opened just Advanced -> Status page and could observe all connected
devices (with different interface as wireless as ethernet).
