Keep your modem or router firmware up to date
Learn about keeping your modem and/or router firmware up-to-date.
Just like a Mac and AirPort base station, network modems and routers use built-in software (called firmware) in conjunction with hardware to provide network services, such as Internet or email access.
In order to function properly, you should make sure that the firmware installed on your modem or router is up-to-date. If it isn't up-to-date, you may encounter issues when trying to connect to the device, or when connecting to the Internet via the device.
Some modems or routers have special procedures that must be followed to update firmware. If you are uncertain how to update the firmware, contact the manufacturer of the device. You should know the device model number and revision (if applicable), which may be printed on a label on the device itself.
Usually, modems or routers ship with the most recent firmware available for the device at the time it was shipped. However, the firmware may be updated between the time the modem or router was shipped and when you started using it, and you may need to update the firmware as soon as you start using the device.
