WLAN stretch

[itsmoked]

Can you set up a WLAN so you have three routers (Example: Linksys WRT300N Wireless-N Broadband Router)

[red]ROUTER(wired LAN A)[/red] - WRT300N - WRT300N - WRT300N -[blue] ROUTER(wired LAN B)[/blue] - [green]DSL
[/green]
The object, is of course, to get access to the DSL from LAN A.

The middle WRT300N would have no wired connection at all. It would simply be a range extender to interconnect the other two.
I keep finding information that hints this is "easily done" but cannot actually find anything concrete.

"range extender"

First - I'm no expert.

But, I read somewhere that to do range extending you either purchase a range extender, or you purchase a normal router that can be re-flashed with after-market/freeware firmware to provide this abnormal function.

The leading unit for this sort of white-hat hacking seems to be the WRT-54GL (L for Linux). It used to be that you could just buy the normal WRT-54G and reflash it, but reportedly you now need the L version (WRT-54G version 5 isn't Linux).

Other reports now say that The Boyz have gotten into the non-L version. But for the delta in price, just get the L.

You should Google WRT-54G and 'version' to get the latest news. It changes monthly. I think that there's good info on Wiki.

Anyway, this should give you enough misinformation to help you find some additional info.

Many thanks VE1BLL. That was the info I needed. Can't be done with standard OTS stuff. Can be done with the right OTS stuff and some reflashing and screwing around. I'd love to go ahead with it but while looking at this stuff over and over it was stated that Direct Line of Site is a must with high gain antennas. My application is one of those almost DLoS projects where one site would be on a flat top of a hill but the other sites are just over the hill's edge.

So I think I'm doomed.

I don't think that your original concept would work anyway, since the upstreaming/downstreaming only occurs in the hardware ethernet. What you'd need is a "access point" that spits out h/w ethernet which would then be connected to wired LAN router as the upstream connection, or a series of repeaters:

Access point:

Note that the Linksys repeater appears to put out less power than their wireless router.

Can you install some 'stuff' at the crest of the hill ?

All you'd need is AC power (or perhaps solar) and a shed.

Hi IR; Yeah the right router with the proper firmware does do exactly what I need and yes the "access points" and that extender are useless in this app.

That's a tough one VE1BLL. The crest is not on accessible property. Any idea how much diffraction over the lip would occur?

How about just putting the receiver antenna on a pole?

"...how much diffraction over the lip would occur?"

[Visions of Mr. Smoked slowly grinding the crest of the hill to a nice sharp edge...]

Even with a sharp edge, you'll lose many tens of dB (much more than you probably could afford to lose). And a link based on diffraction would tend to be unreliable because it would become sensitively dependant on a miriad of details. Long and short - you'd need to blast it with RF and would thus would probably need a licensed system.

If there is a man in the middle (someone's house at the crest of the hill) - then offer him free Internet in exchange for space in his basement.
