run a cat5eor 6 cable out to the garage
Disagree big time.
Until I connected up all our hard wired connections we had 6 powerline adaptors around the house - they were fine, and for a long time we were streaming BBCiplayer using them.
The limit is normally the ISP's speed and for lots of people they are the only option.
Sure a dedicated outdoor rated CAT cable is best but not everybody has the knowledge to do that either...
