#Configuration

Comcast Modem/Router ~~> DDWRT Router ~~~> devices 

# Devices connected to the DDWRT router 
(limiting this to the problem )

A) Raspberry Pi running Libre Elec .... this problem happened in LE 8.x (Kodi 17 based) AND LE 9.x (Kodi 18 based)

B) Dell Laptop

# Various info

- The same Subnet is being used **
- Firewall on or off on the DDWRT router the same behavior (described below) happens 
- Same behavior ALSO happens when the laptop's (Ubuntu Mate) firewall is on or off

## What is not working - Both devices connected to DDWRT router with a wired connection 

- When I have both devices (A) and (B) connected to the DDWRT router, they can not see each other .. I am not sure how to ping from LE to the laptop (or try it ).... but a ping to the pi from the laptop DOESN'T WORK 
- I cant remember where I saw this but I remember "No route to host" somewhere

- when this is happening THE INTERNET CONNECTION on both devices through the DDWRT router DOES work, no problem


- Subnet: 255.255.255.0 on both device
- DDWRT Router IP: 192.168.1.1
- Pi IP: 192.168.1.113
- Laptop IP (LAN ..): 192.168.1.119



## What Does work - Pi connected to DDWRT via wired (same as before)  - but laptop connected via WIFI 
- trying this and the pi shares appear ASAP ... instantly ...  and of course doing what i'd normally do (transferring files ..etc) works fine
