deshonlgates :
I share internet with my neighbor to save on cost and recently bought a powerline for a stronger connection and it works only when my laptop is not on the charger but when it is on the charger it stope workingcomepletely
I can't say for sure but I believe it has something to do with the laptop being connected to the houses circuit that the powerline adapter is plugged into, if you have a large battery bank or a plug separate from the circuit used for the adapter it should fix your issues.
