I've looked everywhere for how to do this but I can't really find a full answer.

My neighbor and I share a lot of files between each other, Videos, Music, game saves, etc.

What I'd like to do is be able to share files on the same WLAN/LAN but still use our separate WAN/Internet connection.(Id' love to be able to combine our internet connections too, but from what I've read that's not gonna happen with the hardware we have)

I can't run a Ethernet cable because of logistics, so it has to be done via WiFi.

I've looked into putting DD-WRT on my Linksys E900 router and I'm pretty sure I'm going to do that regardless. I just really need a shove in the right direction to figure this out. I'm sure it's unnecessary but this is how our networks are set up currently(sans the wifi actually bridging the networks)

    You could set up a VPN. Have either you or your friend purchase a router with built-in VPN support, then the other person can set up a VPN connection to it and it will act as if you are on the same LAN, and is secure. You will have to take extra steps, though, to ensure that you still use your internet connection for outgoing connections rather than tunneling to your friends (see superuser.com/questions/313921/…). – Jason C Jun 21 '14 at 23:39

  • All of the current below suggestions (except the one with multiple interfaces) still move the data through your internet connection which means A) slow and B) data usage. In order for this to work properly, you will need a separate network (with separate interfaces on each end) It's not simple, and likely your best bet is to just use a USB key which you can walk back and forth. – Aboba Jun 24 '14 at 15:51
  • I lied, I just realized your best bet is actually to: Setup each of your routers with guest access and configure that vlan to have access to the fileshare but not internet, when you want someone's file, just switch to their wifi and download before switching back to your own wifi. – Aboba Jun 24 '14 at 15:54

Not sure how much data you are sharing but you could consider DropBox. Then you can just sync a folder on your local filesystems; and anything you put in that folder will show up on your friend's machine. The free service gives you 2GB of storage. The $10/mo service (which I have and love) gives you 100GB.

Another option is a VPN, one of you can get a VPN router and the other connects. Then it behaves as if you are on the same LAN, and you can use your favorite network filesystem. I'm not very knowledgeable in VPN setup though, and you will have to take some extra steps to still allow use of your own internet connection (see Why does connecting to my work VPN cause my internet to not work? for a Windows solution).

If you're willing to spend money, for $250 there is this Wifi bridge with a 3-mile (!) range. You'd need line-of-sight. You'd still have to take care to separate your internet connections (if you have multiple network interfaces in your computers this part is easy, or you could add USB wifi dongles and have a dedicated wifi network in your houses for it) - I'm sure there's well-established ways to set that up but again, I'm not a big IT guy.

The FTP server setup is another great idea. You wouldn't have the middleman that you have with DropBox and you wouldn't have to pay for the service. Whoever is running the server can use a free dynamic DNS service to give you a consistent host name instead of memorizing an IP. The remote user can mount the FTP server as a drive, the person running the server can share convenient folders.

Another quick hack (giving Windows an example but any network filesystem will do) is to have one person set up a Windows share, use DynDNS or share your IP address with your friend, and open UDP and TCP ports 445 (I think). Then your friend will have access to your shared folders. I can't speak for the security of this.


Have you looked into BitTorrent Sync? It seems to be your best fit.

You both install. One of you creates a new share folder, generate a key. The other creates a new share folder, uses the key from the first user. Files are now automagically synced. There's some decent code in it for getting through firewalls and NATs and such.

Upside, no router craziness, you just install files for both of you. There are clients for most OS'es, including iOS and Android. And it's all local non-cloud (DropBox does fingerprinting of certain files). There's even a way of getting a plugin for FreeNAS. There's no FTP uploads. You "upload" or share by copying your file to a normal folder. You can have multiple share folders. One for your personal stuff. One for your neighbor share, etc. Recent versions also do pic backup from iOS (maybe android too). You can even share from a distance - take your movies on the road on vacations. Want to add a third? Give them the key.

Downside (maybe) these are copies of files. You'd both have these big files on your machines. (Though mobile OS versions don't automagically download files).

All media being licensed of course


My suggestion would be to start a FTP server of the files that you wish to share and share them over the internet, as far as I know, without dual radios/SSID's and some crazy setup or a VPN, which would be over the internet there is no better way.
