I wonder if anyone here as any ideas to this slight problem - My old man has brought a house in a semi remote part of France and basically can't have a phone line installed ever!!
His neighbour has a phone line and DSL connections but is about 500m away with trees etc inbetween.
Is there any reliable way to network over this distance as I understand CAT5 won't do it??
