What Is USB Tethering And How Do You Enable It For Mobile Hotspot?
There are times when a physical connection works better. Here’s how to set it up.
When you think of using a smartphone as a mobile hotspot, the wireless version is probably what comes to mind. But there’s also USB tethering, which lets you share your phone’s cellular connection with a computer over a cable. Here’s how it works, what it’s good for and how to set it up.
For most people, a wireless hotspot is still the easiest way to get a laptop online when you’re away from regular Wi-Fi. It’s more flexible, supporting multiple simultaneous connections. And unlike the USB kind, you’re free to move your phone away from the computer.
But there are some cases where USB tethering could make sense. A wired connection can be more stable, which is handy for crowded places like convention centers or airports. It also means you aren’t broadcasting a visible network in public. As a bonus, your phone might charge while it’s connected.
Before we dive in, note that there’s one big catch: Android phones can’t tether via USB to a Mac. (You can still use a Wi-Fi hotspot instead.) Otherwise, USB tethering works with other phone-to-computer setups, including Android to Windows and iPhone to Mac or Windows.
If you’re tethering from an iPhone to Windows, you may need to install the

USB tethering usually makes more sense for one device than as a full hotspot replacement. So, for example, if you’re trying to get both your laptop and tablet online at the same time, a Wi-Fi hotspot is the solution.
Keep in mind that laptops can burn through data with background tasks like updates and cloud syncing. Your carrier may also limit hotspot use, charge extra for it, count it against a separate data allowance or not support it at all. So it’s worth checking your plan before tethering over USB or Wi-Fi.
And while a wired connection can be more stable than a wireless hotspot, it’s still relying on your phone’s cellular signal. Spotty service will still mean spotty internet, no matter how you connect.
