802.11b/g Hughes Net configuration
I've been asked to setup a wireless net with 2 or 3 remote locations in different directions (up to 600 feet) and differing elevations at a location
farther South in Baja. Since I'll need a DSL Router feeding an omni-directional external antenna for the host location, I'm looking at the products
which have removable stub antennas (SMA or TNC connectors). While I've had good results in other applications with the Linksys routers, a concern for
this application is the fact that they have (two) antennas. I'm wondering how it will affect the output balance and resultant output performance if I
connect one of those two via coax to the outdoor antenna. I've sent a Q to Linksys support, but so far, no answer.
Alternately, there are a few D-LINK and Netgear Routers which have a detachable stub antenna.

I am using a WRT54G with one on the stubs out thru LMR400 of about 50 feet to an OMNI antenna and providing signal for about a mile.
The receiving units are using a variety of adaptors. One is connected to a Parabolic antenna, again with LMR400 into a PCI card (Linksys) in their
desktop. Great reception.
Most others are using Linksys WUSB adaptors, B/G mixed. Signal is about 4 bars 1/2 mile away over and thru trees.
Seven users at the present time. Fewer in the summer.
The OMNI antenna came from Freeman Anderson http://www.fab-corp.com/
and I ordered it with a pigtail to go from the lightning arrestor to the router.

BTW, chances of getting a response from Linksys are pretty slim. I believe their techies are hooked up on the cable break of late in the orient.
You can get good answers from Freeman/Anderson. This is what they do.

Outstanding
Thanks for the info. What you're describing is identical to what I had in mind, except that my reception distances are less. I'll check out the
referenced website.

The older Linksys Routers do allow change in diversity, however the newer WRT54G does not seem to have that function.
The upside of it is that you can MAC Filter 40 addressees on the WRT54G.
My setup is running an OMNI off one antenna, and the other is in use for local/inhouse use. No loss of service to either.
With a limited distance run I would suspect that changing diversity would not make much difference, however, if needed, the Linksys WAP11 will provide
the ability for diversification, but a fewer number of allowed/disallowed MAC addys.

On the Way.
Just before noon, I finished ordering all of the necessary equipment, including the Linksys WRT54G. I ordered the antennas, cabling and USB Network
adaptor from the www.fab-corp.com website that you recommended. As presently envisioned, the site will have one host and three remotes, but I'm sure that might
increase with time.
Thanks for the info.

If you are using Hughes system for this operation, I might suggest that you upgrade your service to the Pro Plan. The faster(?) up/down makes a
significant difference if more than one client is online at the same time.
This will be fun BTW, only thing the host has to be on 24/7 or you get some po'd peeps.

Oh Bill,
Make sure you get the pigtail in other than the LMR400, and that its RP-TNC. Just let FabCor know what you are connecting to. They will fit you up
properly.
Dang it, I am really building my post count up. Look out you posters!

By 'host', do you mean a computer or the HN modem?

I hope that host means the modem. Cause without the modem there is no real reason to have a network working.
The 'host' computer has no relative bearing on this idea. It can be turned off as long as the modem, router and any other signal booster is turned
on.

Considerations
A few weeks back, when I was approached with the questions, I put together a sheet of "considerations" for the parties involved. At that time I noted
that the "Host" supplying the Hughes Net access via the Wireless Router might consider a higher service level IF it was anticipated that there would
be concentrated usage by any of the participants. Of course, the reply was that it would be mostly for e-mails and "some" casual browsing, but I've
heard that before. I also noted on the sheet that the only equipment that MUST be on at all times for remote service was the Modem and the Router.
This is the (original 8 1/2 x11) sketch I created at that time. The bottom edge of the original is cut off in this view.

Bill,
reading your initial post on this thread you point out that you would be needing ' DSL Router feeding an omni-directional external antenna ', please
remember tht the Linksys WRT54G is NOT a DSL router and probably would not work.
Also remember that the OS should be XP not some earlier version. This was pointed out to me by Mexibob, who found tons of trouble trying to get ME
to work with the router. It was no joy!

NOW I'm Confused !
The descriptive literature on the WRT54G specifically states that it functions as a DSL Router to connect broadband to the Network. From the Website:
Top Value Buy.
Linksys WRT54G 54Mbps 802.11g Wireless Router.
Wireless-G is the 54Mbps wireless networking standard that's almost five times as fast as the widely deployed Wireless-B (802.11b) products found in
homes, businesses, and public wireless hotspots around the country — but since they share the same 2.4GHz radio band, Wireless-G devices can also
interoperate with existing 11Mbps Wireless-B equipment.
Since both standards are built in, you can protect your investment in existing 802.11b infrastructure, and migrate to the new screaming fast
Wireless-G standard as your needs grow.
"The Linksys Wireless-G Broadband Router is really three devices in one box. First, there's the Wireless Access Point, which lets you connect
Wireless-G or Wireless-B devices to the network. There's also a built-in 4-port full-duplex 10/100 Switch to connect your wired-Ethernet devices.
Connect four PCs directly, or daisy-chain out to more hubs and switches to create as big a network as you need. Finally, the Router function ties it
all together and lets your whole network share a high-speed cable or DSL Internet connection, files, and other resources such as printers and hard
disk storage space."
----------------------------------------------------------------------------------------------------
The connector issue also leaves me wondering since all that I read, including an adaptor table on one of the supplier websites shows the Linksys (all
models) with RP-SMA connectors, not TNC.
What am I missing ?

I have been using the Linksys WRT54G with Telnor DSL for 2-3 years with no problems.

I use a Linksys WRT54G connected to the DSL modem supplied by Prodigy, and we've run as many as three Macs over the wireless network, plus our stereo.
And for a while I think a neighbor got on too.
I assume that Bill's satellite modem delivers a broadband signal to the WRT54G that it can broadcast.

All of the above information is correct. This part,
"Finally, the Router function ties it all together and lets your whole network share a high-speed cable or DSL Internet connection, files, and other
resources such as printers and hard disk storage space."
is also correct. However, this doesn't state the Linksys router is a DSL modem but connects to a DSL modem.
That was the clarification that needed to be made. It appeared by your post that you may have thought the Linksys router was a DSL modem, it isn't
but works and plays well with a standard DSL modem such as Infinium, those used by TelMex. This is also verified by Don Alley's post.
Check closely again about the connectors on the Linksys router and WAP. Unless something has changed within the last year or so the connectors are
RP-TNC.
The idea of this type of connector was to keep users from using anything other than the rubber ducky antenna that was approved by the FCC. This was
to keep the wireless signal within the limits set by the FCC.
However, someone decided external antennae could be connected to the Linksys equipment if this strange connector was duplicated. It was and they
have.
Radiolabs.com will list the correct connector for you starting with the Linksys WAP.

I have connected a number of different antenna to a WRT54G and it works just fine. I normally set the appropiate antenna in the software but auto
will still work just fine. Be careful as some software counts right and left from the front and other software does it from the back of the router.
The weak link in the WRT54G is the switch that switches between antenna. If you lock it to one antenna that switch is not working and you may well
get a longer life. Here are some Antenna that I have tested and you will find a picture of a WRT54G connected to a 3 foot dish.
http://windsurf.mediaforte.com/wifi/wifi_antenna.html
Be careful if you load after market software, that you get a version that works with your router. The full feature software works with the WRT54G
version 1-4, WRT54GL, and WRT54GS. Version 1-4 are no longer made. Version 5-7 take a much smaller version but they can be updated.
If you choose to flash to DD-WRT #23 SP2 it will make this little $69 router into a box that would normally cost over $1000.
My 3 foot dish is running a link ths is over a mile and it works well. The real problem is getting it all water proof. I have ruined one router by
getting it wet. Even afer it was cleaned and dryed, it had lost some of its receive sensitivity.

Good Information - Thanks
There are a number of interesting points brought up and one clarification which indicates that I should have not relied on the Connector table which I
did. That table had shown the Linksys Router connector as RP-SMA. After being advised via this thread, I went to the Linksys website and verified
that the correct connector for that Model Number is an RP-TNC. I sent a correcting e-mail to the supplier, but as a hedge, I'm ordering some
connectors to correct the cable myself if necessary.
I'm not sure why there was some confusion regarding the "Modem" / "Router" function. I had always intended to connect the Router TO the Hughes
DW6000/7000 Modem. Also, when I discuss DSL, I'm including the Satellite Broadband. If it functions with DSL Broadband, it functions with Satellite
Broadband.
Something interesting I also noted when looking at the Linksys Website is that they offer 5.0db "High-Gain" antennas to replace the 2.5db stock units.
Those apparently don't exceed the FCC limits noted above.

Does anyone know where I could find a shopping list for a set-up where I want to share a connection between one house with a Directway connection and
a second house 1/3 mile away? Both have 120v.
I'm looking for a simple, not hugely expensive set-up that I can rig up at a friend's place which I'm going to use for the summer. I'm hoping to
borrow the internet connection from his main house.

joel ... go to the site recommended by losrfrailes. http://www.fab-corp.com/ I did and the sent them an e-mail. They got right back to me with a list of the basic needs for a half mile system.
Russ,
Thank you for contacting FAB-Corp.
I recommend that you connect an access point to one of the ethernet ports on your router. The access point plus an outdoor antenna will become the
point of connectivity for your neighbors. The router with the stock antenna will be your point of connectivity around your house.
Below please click the links to my website to view the necessary equipment for network:

http://www.fab-corp.com/product.php?productid=2425&cat=2... (antenna)
