What I'm "expecting" is not a specific topology. I would set up some
topology on top of it. I might expect some default topology to already
be set up for less sophisticated users to be able to get up and running
faster. But that "expecting" implied being able to make box A talk to
box B wirelessly. I can do that with ethernet regardless of what type
of boxes A and B are. I expected the same from wireless and have seen
no online documentation that says I should expect for some boxes to NOT
be able to talk to certain other boxes, even of their own kind.

It has a static IP. Everything is in 169.254.0.0/16. But I cannot reach
the printer from the computer. I can reach the WGT624, and see that in
its list of attached devices there is the MAC address of the HP 6980, but
without an IP address (which I presume is because it has never seen any
IP type traffic with it). Apparently my ARP broadcasts from the computer
are not reaching the printer.

Linux <-CAT5-> wire switch <-CAT5-> bridge <-Air-> WGT624 <-???-> HP6980

When I wire up like this, I can print:

Linux <-CAT5-> wire switch <-CAT5-> WGT624 <-AIR-> HP6980

But then I can't reach an isolated (future) DSL connection:

Linux <-CAT5-> wire switch <-CAT5-> WGT624(1) <-AIR-> WGT624(2)

But for the DSL, it seems this might work:

Linux <-CAT5-> wire switch <-CAT5-> bridge <-Air-> WGT624 <-CAT5-> DSL

I also tried this:

Linux <-CAT5-> wire switch <-CAT5-> bridge <-Air-> WGT624(1) (future DSL)
same switch <-CAT5-> WGT624(2) <-AIR-> HP6980

That did work when the bridge was peered with WGT624(1). However, it
sometimes peers with WGT624(2) instead, which break things (and gives me
nice broadcast storms). I presume using different SSIDs will fix that
but I have not tried it, yet.

So this is just a too cheap bridge. Given there is no manufacturer name

Apparently not. But what I want to do is figure out WHAT gear I should
use, and do so by figuring it out from clearly written documentation,
which I have not yet found. Such documentation would obviously have to
state exactly what devices (or classes of devices) can, and cannot, talk
to each other (including of its own kind), and for classes of devices,
also tell how to determine which commercial devices are of each class,
despite misleading sales/marketing jargon and puffing.

|
| True.

I actually chose those models for their extended range technology, which
the WGR614 did not have, on the basis that it might increase my chance of
being able to reach between the houses (I always understood this much was
never a certainty). So whatever device classes would interconnect the
two wired LANs, I'd like to have it with that or some other range extend
technology.

And it would be a big plus if one of those would ALSO talk wirelessly
with the WGT624 so I can have ONE wireless device on the wired LAN in
this house and have it talk wirelessly to both the WGT624 to reach the
DSL, and whatever is at the other house to reach it's LAN.

And reaching the printer is important, too. If that has to be through
a double hop from the wireless device on the LAN to the WGT624 on the
DSL and back out over air to the printer, that's fine, as the printer
bandwidth isn't an issue.

I can't say what the network topology is, because I don't know which one
would work in wireless. I've been trying a few I know would work wired.

The picture you show is one possible way, although incomplete.

If youw ant to figure out the best topology for me, here are the parts:

-- my house --

1. My "computer farm" running on a wired switch. Using wireless PC cards
here is not an option. 3 ports are available on the switch.

2. My future DSL connection. It shall not connect to anything by wire.

3. Wireless printer. It cannot be connected to the computer farm by wire.
But a wireless print server might be an option for it (though that
would sure seem silly, and a bit inconvenient).

4. My sister-in-law's laptop, with some wireless card, but not connected
to the net anywhere by when taken to work. THIS is for when she comes
over and brings it here.

-- brother's house --

5. My brother's Cable modem.

6. My brother's Windows computer (currently connected directly to the
cable modem running the cable provided software).

7. My sister-in-law's laptop, with some wireless card, but not connected
to the net anywhere by when taken to work. THIS is for when she has
it at her home.

8. File server I will place in my brother's house in the future. It may
be possible to use a wireless PC card on this. It will be Linux

9. My nephew's computer, not networked at all, yet. Probably will be dual
boot Windows + Linux.


I need the following reachability, whether by layer 2 or layer 3:

1 2 3 4 5 6 7 8 9
1 . Y Y Y - Y - Y N Y = a must
2 Y . N Y N N N N N! + = a plus
3 Y N . + N N N N N - = might be useful
4 Y Y + . N N N N N N = no need for it
5 - N N N . Y Y + N! N! = I really want to block
6 Y N N N Y . + + ?
7 - N N N Y + . + ?
8 Y N N N + + + . ?
9 N N N N N ? ? ? .

Note that if 2 devices cannot reach each other, but both can reach computers
in the computer farm, I can set up routing for them on a computer there.
Don't assume same for the file server in by brother's house as that is
likely a year or so away.

I want NONE of the connectivity to go through the public internet for
reasons of utilization. E.g. the idea of having wireless between houses
is to avoid using the internet for it. Security isn't the issue, but
racking up bandwidth utilization on either the cable or DSL is. I want
inter-house communication to work even if DSL and/or cable is down.
