Charging the Novatel MiFi while using WiFi

The Novatel MiFi is one of the most innovative and darn useful devices to have been released in the last couple years. For all its merits, the MiFi is plagued with a dark secret: for some oddball reason, Novatel decided to disable wifi functionality while the MiFi is plugged into a computer’s USB port. They say it’s a “safety issue,” but my guess is that they don’t believe many computers put out the required 500ma required to charge the thing while its wifi and EVDO radios are both up and running.

There are a number of hardware solutions to this issue, ranging from various USB adapters to cable surgery, but since they require purchasing additional hardware, this solution is not always available when you’re on the go and need a quick wifi fix. Since Novatel disabled the harmless firmware hack in the latest update, I set out to find a quick solution that the weary road warrior can bust out in the most dire circumstances. Fortunately, the answer is found in our multi-tasking friend: tape

At the root of the issue is the MiFi’s search for a data signal to indicate its connection to a PC. As such, simply covering the middle two pins of the USB connector succeeds in transforming any normal USB cable into a power-only USB cable. The type of tape used will dictate how permanent the fix is, but just about any tape should work in an emergency situation.
