So I set up a NAS recently and connected it all up using Powerline 500 devices but the speeds I'm getting are rubbish (syncing at 150-337mbps and transferring at between 4MB/s and 10MB/s). As I can't get ethernet connecting the three devices I'm wondering if ac wireless may be a better option? Is there anything out there at the moment at reasonable cost that will give me a better connection over wifi (would need to be USB adaptors into a synology NAS and a computer as well as a Router)? I understand I won't get Gigabit speeds but maybe faster than the powerline speeds!
