    • A generic powerbank with 2 usb outputs (Amazon DE, Amazon US)

    • A nano sized router that is powered via USB (Amazon DE, Amazon US)

    • A cable spool that is not too large but neither too small. I got mine for free in a local hardwarestore (Obi here in Germany). Just go to the section where they sell chains, because these spools are where the chains are on and if a spool is empty they usually throw them away.

  2. I know this is the hardest part.
    • I know this is the hardest part.

    • While you are waiting for the parts to arrive it might be a good time to prepare the cable spool.

    • Drill a hole (3mm or so) through the marked spot. Be aware not to drill through the inner part of the spool. This hole will be used to put the end of the tether that goes to the topside adapter through it.

    • When you drilled the hole through one side of the spool put around 10cm of tether trough it (I had to extend my wire a bit since i did not put enough of tether through it. see picture 2).

    • Attach the topside adapter with double sided tape or some other non permanent adhesive to the yellow marked place. Make sure that the LEDs are visible.

    • Attach the tether to the topside adapter

    • Now that the Powerbank and the Nano router has arrived unpack everything.

    • Connect the Nano Router to your PC or Laptop with the flat ethernet cable that came with it.

    • The router will assign an IP adress to your pc (make sure that DHCP is enabled)

    • Open up your preferred Browser and type in the IP of the Router (

      • Make sure that the Working Mode is set to AP. If not change it to it.

      • Next we need to change the Adress Type under Network -> LAN. Change it to Static IP and type in the following IP Adress: Leave Subnet Mask to If you didn't restart your Router until this point it is a good time to do this now.

      • Once this has been done we need to access our Router through the new adress. So type in in your browser to access it.

      • Now it is time to give your WiFi network a name. Go to Wireless -> Wireless Settings and type in the SSID. I went with OpenROV for the time being. Everything else I left untouched.

    • Go to Wireless -> Wireless Security and pick WPA-PSK/WPA2-PSK and put your password under PSK Password

    • Check that the DHCP Server is enabled under Advanced Settings -> DHCP -> DHCP Settings. Make sure that Start IP Adress is not but rather something higher (like

    • This should do it for now.

    • Use some double sided tape or other adhesive to attach the Nano Router to the Powerbank - make sure that the USB outlets are on the same side

    • Attach the Powerbank (with the Nano Router ontop) with some double sided tape to the cable spool

    • Connect the short black micro usb cable that came with the Powerbank to the Nano Router (you need to be able to remove this cable later on so you don't consume power from the powerbank when the router is not in use)

    • Secure the construction with some tape and connect everything together:

      • Connect the flat ethernet cable from the Nano Router to the topside adapter

      • Connect the miniUSB cable to the Powerbank and the topside adapter

    • When you plug in the miniUSB cable the OpenROV should power up. Wait a bit for it to be fully booted up.

    • Let's connect to the Wireless network we created previously and connect to the Nano Router (

    • Check for the MAC-Address of the OpenROV under Advanced Settings -> DHCP Client List and copy it or write it down (the Assigned IP will be something different than on my screenshot and it will have a Lease Time)

    • Now go to Address Reservation and add the MAC-Address you previously copied and add the IP Adress, that way the OpenROV always gets the same IP address assigned to it

    • Unplug and plug in the miniUSB cable from the topside adapter to reboot the ROV

    • Once it has booted up you should check if works for the OpenROV in your browser

    • You should now be able to connect to and control your ROV wirelessly

I really like this idea. I'm thinking that it would be great if it was integrated with the tether management system as described by Raymond T. Hightower in this article

Nice writeup! Have you looked at this one? Has a large battery and wifi router in one

Hi Nils,

Nice work with the WIFI integrated...congrats! By the way I am involved in an OpenROV Community on Facebook, especially for OpenROVers based in Germany:

Feel free to join us as well as to invite all your circles and contacts that you know they would be interested as well.

Thanks and talk to you soon on OpenROV Germany =)

I am not tech savy. A couple quick questions: Is a router that can handle 300 mbps better? I noticed some of these for sale near the one you used. Also, the powerpack, is this plenty of power or should a person use an even more powerful one? i.e 15000 mAh?
