For decades now I've seen people beat their brains out trying all the little cheap "fixes" with home gear and software boxes. PITA and unreliable. Since you have $1000 to spend, I would look at business-class Cisco equipment. Most all equipt is 12V on the inside anyway. Just pop the case off and find the voltage regulator board and bypass that with your power. I'm not going to search for you, so go to suppliers like Insight, Tiger Direct, Network Liquidators, etc. You should be able to find a Cisco WAP/router/bridge all in one for less than any effort you're going to put in all these other patches. Maybe go to Cisco first, find your device, then check the suppliers. Good luck.

labatt SD - I do understand the capabilities of the devices. I actually HAVE a DWL-G730AP for when I travel. It will NOT act as BOTH a wireless access point AND a wireless repeater at the SAME TIME with routing enabled. Therefore, you need to have two devices - one for internal access, and one for external wireless access. Yes, you can configure the D-Link as a router, but the upstream connection has to be wired. On my boat, right now, I use a Port Networks MWB-250 as my shoreside wireless connection, and a Kyocera KR-2 as my internal boat wireless router (I picked it since I can switch between the WiFi connection and our Verizon Aircard easily). Please point out a commercially available device, available today, for under $1,000 that 1) Will act as both a wireless repeater and an access point simultaneously, and route between, 2) Runs on 12v, 3) Combines the antenna and board into a single unit that doesn't require running antenna cable up a mast, and 4) Has a high power (1W-ish) high gain sensitive radio/antenna matched combo.

Thadius123 Thanks to everyone for your input and suggestions !

I'll let you know how I make out.

Cheers!

speciald While in a marina, I use a Portnetworks directional antenna/amplifier and a cheap wireless router. Works great.

zeehag wave rv is use-able within 1/2 mi of nearest wifi.....sprint air card broadband dialup is use-able where ever there is a cell signal.......

sailingdog Labatt—

It would help if you knew the capabilities of the devices in question before saying what they can or cannot do. The two devices I mention, as configured, cost less than $300. BTW, D-Link DWL-730G AP can be configured as either a router, an Access Point or a Bridge... if it is configured as a router, then you'd only be paying for one connection.

This is a major limitation, and I've only found two devices out there, one at around $1,500 and the other over $2k that can function as both simultaneously, and as a router. Let me give a scenario. You're in Warderick Wells, Bahamas. Internet costs $30 for three days of access per device. You have two laptops (or in our case, three) on board - one for you, one for your wife and one for your kids. With a bridge, you're forced to buy three logins. With a router, you can hide all your computers behind one connection. On top of that, you can also enforce security through a basic firewall since you're running at layer 3. But - your only choices for doing this today are to buy two different boxes (for most non-tech people, that means learning where to put the devices and how to configure your computers to talk to the AP, the AP to talk to the repeater. and the repeater to talk to shore) or to spend a ridiculous amount of money. Anyway - I got tired of explaining to people how to do it and what to buy, so I decided to start a company and to build a new device with my partner. Jeez - now I'm starting to sound like Craig from Rocna

By the way - Yes, you can set up Internet sharing on multiple computers, but it's flaky and unpredictable. I tried setting it up for others on a few cruising boats and just ended up turning it off.

5MileWIFI Products

This is a long thread on WiFi and they seem to be very happy with the 5 mile Wifi set up

sailingdog The real problem with this as a solution is that it uses a lot more power than using a dedicated bridge, like the Ubiquiti Bullet2 HP and a micro Wifi Router, like the D-Link DWL-730G AP, and it requires that your computer be on all the time.

This also leaves you with some security issues, in that your computer is now acting as a bridge or router effectively, depending on how you have it configured... sharing the WiFi connection from the USB device to the router.

With regards to the actual bridging in the network configuration control panel are there any potential hardware conflicts that I should be aware of?

Would I expect to see any sort of signal or quality degradation with respect to my average speeds I reported earlier with such a network setup?

Thanks for the reply as it was very informative.

Cheers!
