How-To Guides

These are TechnoWifi’s step-by-step guides: the exact menu path, the setting to change, and what to do when the usual fix does not work. Each one is written against the current version of the software or firmware and names the model it was checked on, because a menu that moved two updates ago is the most common reason a how-to fails.

The biggest groups are phones and tablets, with guides such as how to back up an iPhone and split screen on Android; cameras, from setting up a Nikon D3500 to Canon R5 autofocus settings; and home internet equipment, including resetting a Fios router, a Verizon router blinking white and changing a Spectrum WiFi password.

Computers and peripherals have their own run of guides, such as connecting a MacBook to a printer, and the smart home and security camera guides cover Ring, Arlo, Blink and Swann setups like the Ring Floodlight Cam.

If a step on any page does not match what you see on your screen, use the Report an error link at the bottom of that guide. Reports are checked against the device and the page is corrected and re-dated. The full archive follows, newest first; the search box at the top of the page is the fastest way to a specific model.
