Before You Flash Your Device

Reflashing your access point may violate the manufacturer’s warranty and, if performed incorrectly, could render it inoperable. Proceed at your own risk.

Follow flash upgrade instructions carefully. Sputnik does not provide free support for customer-flashed devices. If you are uncomfortable flashing your own AP, consider purchasing pre-flashed hardware from the Sputnik online store.
