Just wanted to share my experience because it took me quite some pain to make it work.
1 - Make sure that your server, NAS or router with usb ports, is able to read 60mbps (7.5 mb/s) consistently.
2 - Use NFS linux shared protocol (Windows SMB is too slow, some blu-rays have peaks over 50mbps)
3 - Use a wired access point on the more stable 5 GHZ band
Hope this can help.
