  • OK, You owe me one. I am all packed to go to Tortola in the AM and had to retrieve my cheat sheet from the bottom of my duffel. :-)



    On the NETWORK tab

    in the WLAN settings select "Router"

    Select "DHCP".

    Down in the LAN setings pick an IP address for the Bullet. Something like 192.168.55.1. Net mask 255.255.255.0

    Enable NAT

    Enable DHCP

    Start Range 192.168.55.100

    End Range: 192.168.55.200

    Click Change but DO NOT apply.

    Clik Advanced tab and set miles to zero ACK Timeout to Auto Adjust nd click Change but DO NOT Apply.

    Click Link Setup Tab and set Wireless Mode to "Station". Make Sure Output Power is Max. Click Change and apply.

  • Now that I've been using the Bullet 2HP for a while I have a few comments.



    First a warning. Apparently there were a batch that were not sealed well where the clear cover is over the LED indicators on the side of the unit. A friend of mine had moisture within his unit that stopped it working. He was able to dry it out and get it working again and the distributor who sold it to him said they would back it up and they were the ones who told him about the potential weakness.



    So far this is the most powerful gear I've used. It's only moderately difficult to use and I was able to download good instructions for a different wifi adapter that used very similar firmware so that I was up and running pretty quickly.



    I find the case and antenna connector to be very strong. I have it hooked up to a yagi at the moment and I can actually use the adapter as a pistol grip and point the antenna around looking for a usable signal. In the firmware you can use "antenna alignment" to view a moving scale of signal strength. While this would not be practical at anchor it would be very useful while tied up at a dock. It would also come in handy if you were desperate enough to need to get off a quick email, you could have someone aiming the antenna for you manually to compensate for boat swing (don't laugh, I've got weather this way!).



    At the moment it's upstairs hooked up to the yagi picking up an open wifi somewhere in the next block over. It's plugged into a Lynksis WRT54G router to redistribute wifi in the house. This all works well enough that I probably will not spend the time and money to upgrade the firmware to DD-WRT.



    We also have a direct connect Omni antenna we can use at anchor and it tests well.

  • I'm vendor and I sell systems based on the Bullet 2HP.



    Everything is correct except that:



    1. I would not put a Bullet at the masthead without some sort of support bracket that can take the shock that can occur when a jib collapses while running down wind in a seaway and then refills with a snap. I believe that the N-Male connector that is the attachment point for the Bullet can be broken by an event like that. You'll be better mounting the Bullet on some stern structure.



    2. Most inexpensive wireless routers will not provide Power to the Bullet. You'll need a passive POE between the wireless router and the Bullet.

    If all that is correct, here are my questions:



    1. Can I use a "mobile" wireless router that runs off the cigarette lighter (12v) power?

    2. If so, will that be sufficient to power the bullet/antenna through the cat5 cable?

    3. Does this limit me in any way?

    4. Am I missing any components?

    5. Any recommendations for the 12dB antenna?




    1. Just about any office grade wireless router will work out of the box with the Bullet. If you get a 12 volt model such as ones made by Linksys, Netgear, Engenius and others you can avoid the cigarette lighter arrangement and connect directly to ships power.

    2. The Bullet 2HP uses about 3 watts and most wireless routers run between 3 & 6 watts. Generally 12 volts input to the POE will let you use up to 150 feet of CAT5e cable. The longest run any of my customers have made is 100 feet.

    3. You won't have any limitations that I am aware of.

    4. You'll need a passive POE and a power pigtail with a 5.5 x 2.1 mm barrel plug.

    5. I prefer an 8db antenna because of the larger beam width but whatever antenna you get, make sure it has a mounting bracket the stands off the surface enough to mount the Bullet.

If you are not at least a little geeky you want to someone who is to do your firmware swap. Screw this up and you end up with a “brick” or an unusable, unrecoverable unit.




    DD-WRT is very capable firmware but most of what it does is not needed by a boater and it is harder to use than the Bullet firmware. IMO the Bullet firmware is the best on the market for a boater.

WiFi Networking for Cruising Sailboats | Adrift at Sea

  • I was over on s/v Itinerant, helping Joe with his WiFi setup, and decided to write what I did. Joe had bought a NanoStation2 based on my recommendation and was having some trouble with it.


    The equipment I’ve been recommending for cruising sailboats are either the NanoStation2 or the Loco2 for monohulls and the Bullet 2HP for multihulls. All the hardware is designed and manufactured by Ubiquiti Systems, and are designed not to require any device drivers.

  • A NanoStation2, a Loco2 or a Bullet 2HP WiFi Bridge/Router with an antenna. The NS2/Loco2 have an antenna integrated into them.


    A Power Over Ethernet power injector tap. This allows you to run a single wire for the data and power connections for the ethernet bridge.


    A power cord for the POE injector to wire into the boat’s electrical system or plug into a 12 VDC outlet. These units can use a fairly wide range of voltages, and will generally be fine with the 12VDC system on most boats. Typically, the units will work on voltages from about 9 VDC to about 24 VDC. Anything above 24 VDC may cause a problem.


    A long ethernet cable, preferably exterior grade for the connection to the bridge unit. This will be connected to the data/power port on the POE injector.


    A shorter ethernet cable for the connection inside the boat between the computer and the POE injector. This will be connected to the data port on the POE injector.


    A computer to configure the bridge with.
