I searched the forums, but did not find anything concrete so..... I just had new internet, cable services installed. The installer located the main box for the service (AT&T u-verse) near a TV and not near my iMac. He used a powerline adapter to run internet to the iMac. However the box does have built in wireless G. I cannot run a hardline from the box to the computer without running a rather ugly line over windows and doors from one to the other. The room is a sun room so I cannot just fish it through the walls. Taking into consideration that I live near Orlando, Florida which has a lot of lightning, and I have had the GFI pop off in the room where the computer and cable/internet box is located, the question to be debated is: Do I keep the connection with the powerline or disconnect and use the wireless? I think that the powerline is probably faster, but obviously makes little difference with the internet. I do have a TiVO hooked up to the network, wirelessly and have transferred programs from the TiVo to the computer. The powerline adapters are plugged directly into outlets because surge protectors filter the signal. And now for your thoughts.
