  1. Hi,

    first of all thank you for the article, very useful. I am thinking about this option for my wildlife photography. Have you tested a stable signal range (with live-view) of this setup? For now, I am using a 25 metre long USB cable which is not very practical 🙂 Will I get at least this range with TP-Link MR3020?

    1. Thanks,

      Glad the post is of use. Using this tethered to my old Nexus 7 tablet I’m able to get a 25 metre range without any problems. I’ve tried it at about 40m with clear line of sight, but I’ve only done a short test at that range so far. There’s a bit of lag on live view, but it works fine. If you shoot raw files make sure you also have low res jpg’s enabled otherwise the link takes forever doing the file transfer.

      1. This is really promising for me, thank you 🙂 I just ordered TP-LINK TL-WR902AC which is for nearly the same price and has 5 GHz option (I know It has worse range, but It is nice feature to have). Also, according to qDSLRDashboard forum, there is no problem with flashing OpenWRT on it. The first I will try after arriving is using it in “wifi extender mode” with default firmware and built-in wifi (Wifi SD card) in my Canon 7D II. Maybe it will work straight out of box with canon official app for remote shooting and there will be no need of flashing custom firmware. Thank you one more time for saving my money 🙂

    1. Hi Oliver,
      I think if you’re looking for a V1 MR3020 you may have to go for a used one on ebay: seems like all the new ones are V3 now.
      Good luck,

  2. hi

  3. update got the MR3020 V1 there other day

  4. Hi John,

    Fantastic article my friend … I was able to grab a v1 MR3020 off FleaBay for £11 … 🙂 … I used the ‘easy method’ with Factory FW and boom! … she’s a runner.

    What a wicked little device this is … I will be testing it to the max, in the field … as well upgrading it with a rechargable battery and other goodies …

    One way of powering both the DSLR and the MR3020 (if mains is available) is with the Canon’s 7.5v DC supply … creating a spiltter cable that will feed the DSLR, as well as the MR2020, via a buck converter down to 3.7v …

    Thanks for a great, easy to understand writeup …

    all the best

  5. Hello, could this same set up to used to send pictures down the network cable output on the device from your camera? this way the range could be extended for 100m or so? How would I configure it differently, must be a setting in the router to send via network cable instead of wireless?
    Thank you

    1. Hi Paul,

      The answer is I don’t know – the OpenWRT firmware should support that configuration, but I’m not sure that qDSLRDashboard’s ddserver will allow using the ethernet as an option. There may be better alternatives out there if you want to communicate over ethernet, but to be honest it’s not something I’ve ever looked in to.

      Sorry I can’t be more help,
