To work properly, make sure that the firmware installed on your modem or router is up to date. If it isn't up to date, you might encounter issues when trying to connect to the device, or when connecting to the Internet using the device.
Some modems or routers have special procedures you need to follow 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 might 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.
