While this isn't related to OMV I thought you guys could help me out, so I created an image for better explaining my issue
I have a main router, from my ISP company that provides internet to the whole house. But it only has 4 ethernet ports, so I have two switches.
On the upper floor there's no wifi, so I have a powerline connected to one switch and on the upper floor the receiving powerline (the powerline is well connected to the other unit) connects to a router (which is configured as an Acess Point) to transmit it to wireless.
The problem is that I only have internet like once or twice a day. It connects but nothing loads, there's no connection, just a "blank" wifi. And yes, the powerline is properly connected, all lights are solid meaning a sucessfull connection.
The DHCP is disabled on the 2nd router, so it should be using the 1st router established IPs, but it rarely works.
Thanks for your time
