I am currently out of range of ADSL in my area by about 100m. I have a
friend who is able to get ADSL although has not yet upgraded. If he were to
buy a wireless router, such as the Netgear DG824M would it be possible for
him to use the 4-port ethernet switch to share the connection and for me to
recieve it 100m away via wireless? If so what would I need in order to share
the connection between my computers without having to buy a wireless network
card for each one. Is there any way I can integrate it with my current
100mbps switch network? If so what would I need?


Many Thanks
 
Sorry, home wireless networks won't reach 100 FEET without interference.
100 meters, no. Sorry.

I think so. You might have to be game for experimentation with the
use of external directional antennae --perhaps on each end. Be sure
to pick a wireless access point and a wireless card that both support
exteernal antennae.

Assuming your neighbor is only getting this access point for your
benefit, you'd need hte access point and a directional antenna on his
end pointed at your house.

At your house, you'd need a directional antenna pointed at his house,
a wireless card into a PC on your end, and NIC in that same PC. You
could then enable IP forwarding (aka routing) on that machine--the PC
becomes a router if you will. Hook the NIC of the PC up to your
existing switch/router into the WAN port. HOok the rest of your PC's
to the LAN port (where they likely already are).

You may have to learn something about IP numbers and submasks and
networks here because you'll be joining 3 IP networks with 2 router,
and it's likely that your PC's operating system won't work as a DHCP
server without extra software, so you may have to manually assign some
private IP addresses in the 10.x.x.x or 192.168.x.x range.

For example, say your access point doles out 192.168.0.x addresses via
DHCP to the wireless card, then you'd want to assign that PC ethernet
NIC to be say 192.168.3.1, then configure your home router/switch WAN
interface to be 192.168.3.2, then configure your home
router/switch's LAN DHCP server to dole out 192.168.5.x addresses.

If the "PC as router" idea doesn't sound that elegant to you, there
might be a hardware appliance that will do what you want, I'm not
sure.

Finally, one directional antenna of which I'm aware is:
http://cantenna.com/

But I'm sure there are others.

Best Regards,
 
Woah! Fraid all that's gettin' me a little confused. Why would I need a
wireless access point? Surely it would be more helpful to have a switch that
supports wireless connections (if that's possible). Or are you suggesting I
connect the wireless access point to one of the ports of my current switch?


Many Thanks

100 meters, no. Sorry.

It is being done all the time. Good equipment and antennas make the
difference. In a case like this, where a point to point connection is
desired, directional antennas are easy to contruct. Cantennas, etc. make it
work. Look in alt.internet.wireless for better information from people that
are doing it every day.

Try asking in alt.internet.wireless for answers from people doing this.

A wireless access point is the thingee that would sit at your friend's
house. Maybe it's a term you're unfamiliar with, but it's just the
little box with an antenna that ya buy from Linksys or Dlink or
whomever that talks to wireless NIC cards. Whether the box you buy
has a wireless access point only, or is a combination wireless access
point, 4-port LAN switch, and router, is up to you.
Surely it would be more helpful to have a switch that supports
wireless connections (if that's possible). Or are you suggesting I

Yes, you could hang a wireless access point off one of the LAN ports
on your neighbor's switch.

And stop calling me Shirley. :-)

The wireless newsgroups are a good recommendation--lots of folks in
those doing exactly what you describe. Do an advanced search of the
last 6 months on groups.google.com in forums *wireless* and see what
may have already been discussed.

If you want to connect two networks you need wifi bridge, rather then
modem/router/wifi AP (DG824M).
100m should be OK provided you have line of sight, preferably trough
windows.

Sorry, you're starting to lose me here. Surely he'd need a wireless
compatible router in order to share the connection wirelessly. Would I
therefore need to buy a wireless bridge to recieve the ADSL connection
broadcasted by my friend's DG824M?

Thing is I currently have a wired network in my house and he has one in his.
If he's gonna share the net connection around his house he'll need a router
(DG824M) to connect to his current wired network. I would then like to
recieve the wirelessly broadcast signal 100m away in my house. What would I
need to pick up the signal and share it around my current wired network?


Many Thanks

The DG824M apparently is an ADSL router that includes an 802.11b
wireless access point. The back panel "Running from left to right:
power input socket, wireless antenna socket, recessed reset switch, 4
x RJ-45 Ethernet ports, and the RJ-11 ADSL socket."

Okay, he needs that router for him to get ADSL service at all. That
ADSL router he has also happens to have 2 additional features: a 4-port
ethernet switch for his local wired lan, and an 802.11b access point.

You need a directional antenna pointed at his house and a wireless
card for your computer. That'll get one computer hooked up.

To get the rest of your network hooked up, you'll want a regular old
ethernet NIC in that same computer, and to enable routing (sometimes
called IP forwarding) on your computer. In windows, here's a guide as
to how to enable that:
http://www.wown.com/j_helmig/w2kprout.htm

And hook the ethernet adapter to your switch, or WAN port of whatever
router/switch you might have. You've said you have a home network,
but I haven't seen you mention what you have specifically for your
switch, so it's hard to help you further.
 
If both networks are already wired, why wouldn't a router on the ADSL side
and a wifi bridge or a WAP11 in access-point client mode do the job? I've
never done this, but I'm not sure I understand the need for enabling IP
forwarding anywhere. Can't you just connect the switch to the WAP11 or
bridge?
 
It's possible that you could possibly connect all your computers
individually by wifi to the DG824M, which would be simple, but probably
wouldn't work if the distance is 100m unless you can position all the units
by windows all with direct line of sight of the DG824M.

On the assumption that it won't work I was suggesting that you use wifi
bridge to link your two networks.
This is a pair of directional wifi transmitters / receivers working one to
one and essentially replacing an etherent cable link. These can be
positioned for best connection. One of them will connect to a ethernet port
of the DG824M, the other will be on your end connecting to a switch from
which you run all your computers via existing wired ethernet.

You could....that's one way to skin this cat, arguably the most
elegant one. He'd also need a directional antenna for reliable
performance.

The solution I suggested isn't as elegant, but it is probably cheaper.
It doesn't require that he purchase anything more than the wireless
card and an external antenna, and turn on IP forwarding. Odds are his
existing computer already has the ethernet NIC.

Have you asked your Telco to retest the line????

I see the range has recently gone up to around 6Km. Note this is for
512kb/s

Ok guys here it is,
The friend with the broadband connection in house wants the wireless router.
Then depending how far the router is from the edge of the house, probably a
wireless access point, that supports a directional antenna. Then Steevo you
want a wireless access point in your house, or a wireless router, but they
both have to be able to support directional antennas as well. BUT if you
get a router it NEEDS to be able to act as a access point. The problem with
having 2 routeres on a network is that you have problems with them "arguing"
over who sets the IP, and DHCP etc etc..and it can be more headaches than
its worth. So the final answer is put the router in your friends house and
let IT act as the router, since you are just extending the area it covers
with access points, it will still do all the necessary routing. Oh yeah and
you will probably want to enable some kinda SSL security going over that
long of a range.
