OK, I have done some digging and haven't come up with much on this. I am trying to figure out if there is any equipment out there that would be able to help me with this setup.

I dont' know what's available for this type of thing. I live in the country and have an office roughly 2000' away from the house. I would like to be able to send a wireless signal from the house to the office. There is a clear path between the two buildings and it would not be a problem to mount some external attenas/dishes(?) at either location. I was just wondering if this is at all possible and if anyone has any experience with this.

Any help/comments would be greatly appreciated.

Eqipment I already have:
WRT54G Router
F5D7230-4 Router

That's nothing, people to 8km links with wireless routers. First, you will need two good routers. (The WRT54G series is popular on both sides because of power boosting.) For a 2000Ft link you might be able to get away with using that other router.

The key thing here is getting large, directional antennas. For the 8km link the person used a 29dB antenna so you could probably go for less. Then it should be a matter of plugging it into the router and connecting them.

I have never done this and I'm not sure my info is 100% correct, FYI.

You didn't dig very hard. Literally dozens of threads about this on this board alone, not to mention the to thousands with a google search.

Any wireless bridge point to point or AP/Client setup will do what your asking. Just look for one with detachable antennas, buy a yagi antenena in the 7-11 dBi range with a pigtail or coax cable run from antenna to AP/Bridge antenna post and point.

I'll check out those ideas some more. Thanks for the help. Like I said, I've done some digging, but I probably wasn't using the right "key words" when searching.

What kind of work will you be doing in your office? Just keep in mind that you will not have too much security with wireless. If the info is something that you might not want getting in the wrong hands you might want to consider digging a trench and laying some fiber.

you need a pair of slotted waveguide antenna's ... that should give you more than enough range. you can google for them...pretty easy to make

WPA, mac address filtering and disabling DHCP on the wireless segment should be sufficient. If need be a VPN layer could be added

I've been reading over different things, and I'm a little uncertain about something. I know I need to build/buy an antenna for the "home" base, but do I need an antenna on the receiving end also? Or can I get buy with just the wireless card.

If I do need a receiving antenna also, is it best to have another router hooked up to it, or should I just get a wireless pc card with an external antenna, and plug that directly into the antenna?

I really do appreciate the help/comments thus far. This has been interesting for me to research.

Your best bet is to get a PAIR of routers and set each up with a directional antenna. The one that goes into your office should be set to "bridging mode" where it doesn't do any of the intelligent routing that the main one does - It just acts as a wireless network extender. You can then plug your office PC into the Ethernet ports on the remote router/bridge and it'll be just like it's connected to the network in the house.

Well, besides the WRT54G with third party firmware I don't know of any other Router/AP combo's that bridge, and even the linksys doesn't do it natively.

You could use a wireless card on the remote site if that was the only workstation you had out there but yes, it will certainly need an external antenna.

The WRT54G is now at version 3 and as far as I know the third party firmware doesn't work on it. COuld be wrong there. SOmeone correct me if I am.


What you need if your going to run the parent device, be it an AP/Router combo or dedicated AP in ap mode, is a workgroup bridge. You may hear Client Mode AP, or wireless ethernet bridge, at the remote site which can either uplink a single machine or a switch for multiple machines.

Buy your antennas

The Buffalo Tech. 802.11g line can Bridge as is (no need to flush expecpt while in the batroom), it has a plug ready for external Antenna.

Some Models of the Belkin 802.11g can Bridge too.

The buffalo as is a better unit than the other Brands Wirless hardware. If you get the AOSS type it is very easy to set WPA.

It also has a classical look as oppose to the Horrible Blue.

Ah, but some people actually like the blue/black over boring beige...
