Friend of mine has terrible WiFi signal in their garage. They have a decent router by Netgear, but I don't see upgrading a necessary step. Instead, I would like to run a powerline ethernet set-up out to the garage with a wireless access point. Is this set-up possible? I'm sure the access point would be limited to the powerline adapter's performance. I just would like to know if the set-up is possible before I start my purchases and would have to take my product back or send it back.
