I have a non-laptop Shuttle computer on my sailboat. I would like to be able
to access marina and other WiFi points when available. I have talked to some
of the marine WiFi providers and they only provide hardware that works with
laptop computers. At the Oakland boat show the provider I talked to wouldn't
even look at me after I said I had a desktop computer instead of a laptop!
I would like to set up an external antenna and the necessary hardware to get
WiFi access into the Ethernet port on my computer. I have no laptop PCMCIA
slots, no PCI bus slots, only a high-speed Ethernet port. I am not looking
to have secondary wireless access for other devices on the boat.
I would like to be able to install a wired router on the boat and share the
internet connection among more than one on-board wired computer. This would
eliminate USB wireless adapters that connect directly to the computer.
Can I use a bridge, like the Linksys WET54G, for this application or is
there a better solution? Recommendations for an external antenna would also
be appreciated.
Thanks, Rusty |

You might try a EUB-362(EXT) high power (200mw) USB wireless adapter with an
8.5db marine antenna on the Shuttle, hard wire in the other PCs through a
workgroup switch and use the Windows ICS facility to share the connection.
The EUB-362 is especially attractive because you can run the USB cable up to
15' and locate the EUB362 close to the antenna. With a powered hub at the
end of the USB cable you can go another 15' and take the load off the
Shuttle all together.. At 2.4Ghz LMR200 coax will loose more than 50% of
the signal over 20' but only 15% over the 4' that comes with the antenna.
Also working off the USB port the Shuttle will own the adapter so you can
scan for access points and control which one it connects to using the
standard wifi utilities. You can't do that very easily with a wireless
router.
To give you an idea of the performance, using a 200mw Senao card connected
through 16' of LMR100 an 8.5db antenna I could get a usable signal from the
500mw BVI Marine Wifi access points out to about 900 yards. The thin LMR100
lost 75% of the signal so a shorter length of LMR200 should get you out to
1,500 yards or better.

Glen,
You make a good point about being able to scan for access points. I think
the bridge comes with software for scanning, but a USB adapter would make
that very easy. It would also make for a simpler setup until I decide to add
a router.
Any recommendations for an external antenna?
Thanks, Rusty

You might consider this whole kit from Netgate:
http://www.netgate.com/product_info.php?products_id=328 It comes with the
EUB-362(EXT), an 8.5db marine antenna with mount and a 20' LMR200 cable.
The antenna is pretty well built but it comes with a deck mount rather than
a rail mount and will not fit some rail mounts. There is a guy on eBay with
a store called "War Driving World" selling 9db marine antennas. They are a
little more expensive but you have a choice of deck or rail mounts
Depending on how you want to mount the EUB-362 I would ask for a shorter
cable to minimize loss. I am running USB to right under the antenna and
just using the cable that comes with the antenna to get the least possible
loss. Both antennas and the 362 have RP-SMA jacks so you have to use a male
to male RP-SMA gender changer to connect then directly. (about $5 on ebay)

Yes, I do this now in our boat. I have a Linksys WRT54GS with the dd-wrt
firmware loaded on it. It's configured for "wifi client mode" and handles
making the connections to shore sources. To that I have a PC wired. I also
have another access point wired to it providing an on-boat Wifi SSID. Our
laptops connect to this. This way the laptops always connect to the same
SSID. I only have to visit a wireless client status page and make a
connection to the on shore SSID. Works pretty well. I'm about to
permanently install some antennae for it, probably some 8db sticks on
ratcheting marine mounts.

NetStumbler free from http://www.stumbler.net/
Connect your GPS to the computer and NetStumbler will log GPS position
where it finds each wifi point, automatically, then will interface with
Google Maps and Google Earth to draw you a Wifi map of any place on the
planet....(c;

The USB adapter is an external box that just plugs into the USB port I
assume it has, right?
That'll work just as good...(c; >> Stay informed about: WiFi Access |

Yes, it has several USB ports. That is probably the way I will go.

I'm on my boat right now. Just installed an EUB-362(ext) works very
good. I've been using a smc 200 mw pcmcia client so far, but only b
protocol. The big attraction is EUB supports G protocol at 200 mw. I've
had a 8db ext ant for a few years. I would stay away from LMR100 and
LMR200, go the best, LMR400. Something like .25 db loss per meter
(about 1 db loss per 12', not bad). I already had an N connector at the
nav station, so got a N to rp-sma adapter. I may eventually shorten the
LMR400 cable & run an active USB instead.
For more info of my previous setup and info on War Sailing, check out:
http://www.catalina42.org/war-sail/
I know EUB claims it supports Netstumbler (NEED their new drivers on
their web site, supplied cd does not work). It kinda does work, but
after about 1 min, all AP's go to grey and none are available. Have not
figured out why yet. Has anyone seen this? (Running XP Home, SP2, runs
Netstumbler perfectly with my older SMC card). Tried it on another
laptop, same results.
