After several months of spending what time I could spend googling and searching through all of the complaints and explanations that I could find as to why EOS Utilities would not recognize my T6i, and using trial and error on my own ideas of why, I finally figured it out. You have to do things in a specific order to keep connection long enough to get your camera connected to the EOS Utilities long enough to connect the camera to other devices. A few weeks or so after buying the camera, I made the mistake, while I was away from home with my camera and getting in a hurry to post pictures, of connecting my camera to my cell phone and loaded pictures onto Facebook. I had not had much time for doing much else previously with the camera but taking pictures and connecting it to the computer and downloading the pictures and videos to a flash drive via the computer and then sharing from my computer. After connecting my camera to the cell phone, the next time I got ready to download my pictures to a flash drive via the computer, the Cannon Utilities would not recognize my camera any longer. After messing with it for a while, I wandered if my connecting the camera to the phone had something to do with it and I kept googling how to fix the situation. But, nothing that I found solved the situation. After several weeks of searching for the answer during my spare time, I finally went to the reset the camera connection by enabling the Wi-fi/NFC and then going to Wi-Fi function and choosing the camera icon. I then I chose GENERAL SETTING and then I chose CLEAR WIFI SETTINGS and I set my camera back to default. I then turned off the camera, the computer, the Wi-Fi, and the internet for a while to make sure all connections were thoroughly disconnected. I then logged the internet, Wi-Fi, and then computer back on again. I connected my camera to the computer with the interface cable. I turned the camera on and click on the EOS Utility icon on my desktop which brought it up. It had choice that said something to the effect of connect by LAN or CLOSE and I clicked on the connect by LAN, or whatever that connect t choice stated. I then clicked on the start menu on my computer and chose EOS WEB SERVICE REGISTRATION TOOL. I followed the instructions that I had found on the canon web sites that I had googled on how to register your camera to Canon Image Gateway, Facebook and such. I made sure that the Nickname I gave for my camera was the same as the one I had given previously for the cell phone nickname connection. I register for the Gateway, Facebook and such and then transferred to the connections to the camera side of the form as per the instructions. Then after completing that task, I disconnected from the function and went to the room where my Wi-Fi station was connect to my internet and went into the menu on my camera and went back into the Wi-Fi connections on my camera screen. I chose the globe setting for connecting to the Wi-Fi and followed the instructions to select the WPS and connect using the WPS button on my Netgar Wi-Fi for each of the Gateway and Facebook. After getting all of that set up, I disconnect and started all over again connecting my cell phone to the camera again while making sure the camera nick names were the same.
