You might want to consider NOT connecting the camera to the computer. The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive. Or you can use any photo cataloging program.

Hello: Try updating the firmware for the camers and software. Go to canon and download the firmware to a flash drive and connect your camera and install the latest firmware from canon.

How I helped myself:
1. Exited WeFi installed lately
2. Went to Canon website, downloaded WIA Driver, reinstalled, restarted computer
3. Exited WeFi again (after restart)
4. And it works!

Try changing the "communication" setting on the camera from "PC Computer" to "PTP"
Menu > Tools2 (wrench/hammer/2) Communication = Print/PTP

Go to the Canon website and download the EOS Utility. All the software for your camera is there for download.

most ALL cameras(photo)do not need software to load to a pc(exept maybe vist)
in any case,go to the makers website and brows to support or downloads,they will have software and drivers.

your other option,which in my opinion works the best on any computer or camera,is simply to buy a usb cardreader for your memory stick.

insert the cam memory into usb adapter,and plug into ANY comp.
it's that simple!!

You need to install the correct software on your computer. They are usually called drivers. Here is a link to the Canon Rebel Xt page from Canon with all sorts of goodies you can download. The most important section to get things going for you is the drivers. Select your OS from the drop down list, download and install. If you don't have drivers your PC or Mac doesnt recognize the fine piece of hardware... your camera. Hit me up if you're still stuck.

not a user serviceable problem
