GoPros love water. One of the best things about them is that you can take them where other cameras fear to go. Whether that’s hiking in a downpour, snorkelling over a coral reef, or surfing big waves, GoPros are up for it.

But that’s not to say that every function will work in all conditions. As one example, you can’t control a GoPro by wifi underwater. That’s true even if it’s only the camera underwater and you (and the wifi remote or device) are above water.
That’s not a shortcoming of GoPros. It’s true of any camera, phone, or device using wifi. The problem is that wifi waves don’t work at all well underwater. It might be possible one day to set up wifi networks underwater, but for now it’s not an option.
The problem is that the signal drops off very quickly in even a small amount of water. By the time you get a few inches, let alone a few feet, underwater, the signal is to weak to be usable.
So for all practical purposes, you can’t control your GoPro underwater with a wifi signal. That means you can’t use the GoPro smartphone app, nor can you use the GoPro Smart Remote, the GoPro Remo Voice-Activate Remote (even though the Remo is waterproof), or the devices that turn an LCD Backpac into a wireless view and controller.
If you’re planning to film underwater, it’s also worth remembering that the LCD touchscreens won’t work for touch control underwater. They do work just fine for viewing, though.
Underwater Wifi Extension Cable
WiFi itself won’t work underwater, but what you can do is transmit the signal for the underwater portion through a cable. That allows you to livestream from your GoPro underwater.
If you like DIY projects, it is possible to build your own. Or Cam-Do now offers off-the-shelf extension cables for the HERO4, HERO3+, and HERO3 with lengths ranging from 20 feet to 300 feet.
If you want to try building one yourself, here’s a how-to guide.
