Anybody can suggest me NAS that is cheap and reliable so I can transfer file even if I am outside and use it to play file on my media player with using wireless? One more, If I have NAS on my house A and have a media player on my house B, can I play the movie using the media player from house A and NAS from house B? Sorry,just started to learn about NAS
I may have another suggestion, just grab a normal NAS, subscribe a high speed broadband (UNIFI?) with high upload speed, and of course your mobile device must have good wireless Internet connectivity to be able to enjoy the speed.
You should be able to stream just as normal video from any website, as NAS probably has some media streaming features built-in.
Another case is you want to share your media centre (house A) with your media player (house B), may I know which of this option describe between your house A and house B?
1. Your house A and house B is just next to each other, or easily within sight, within 30 meters.
2. Your house A is much further away from house B, more than 50 meters.
For 1) Wireless N bridge is your solution, might be expensive but you can actually share to even your neighbours provided only 1 or 2 streams it at the same time. This is even easier if house A and house B just next to a wall, just provide short outdoor LAN cable link to each device and you're set to go.
2) Slightly tedious as you might spend more on wireless solution, good directional antenna is expensive unless you willing to fork them out.

There's another solution if both house is really far away, UNIFI could be another solution, with the unlimited bandwidth still impose.
All of these require some form of set-up and little knowledge to network solution. Or just cut all the chase and bring huge external HDD.
