FPP CANT REACH CONTROLLER THROUGH ETHERNET IP ADDRESS

[Manuelpereyra78]

Im was fine and the controller board warned me about not being able to access the controller through IP ADDRESS if i changed some setting and exactly that happened.  Now i cant reach the controller through ethernet cable ip address and wondering if i can reach it directly through USB cable.
Anyone else encounter this issue and details please.... 
Thanks

A lot more information required.
1)  What is the hardware configuration - by that I mean, what devices are we talking about and what is connected to what, and via what?
2)  What is the IP configure of the devices - IP addresses, subnet masks, gateways?
3)  How are you trying to access?

The more details, the better.  If the hardware config is complex, add a network drawing.   We're not mind readers.
