My girlfriend is moving into a granny flat on her parents property, its approximately 100-150m away from the house on the other side of the garage. Shes wanting internet access. Ethernet over Power adapters wont work due to being on separate circuits. Not allowed to run a cable from the house so realistically I think wireless is the only way to go. Currently there is a wireless AP on the same end of the house as to where the flat is but theres no way the signal will go that far with what they have. Anyone got any ideas or suggestions? Ive used directional aerials in the past with some fairly limited success.
