Firmware update is responsible for removing the bugs from your range extender and adding new features to a device. You must update the firmware within a given period to level up the performance of the incoming Wi-fi signals. Now a user can automatically update the firmware of the Linksys range extender with the help of the “Check now” option of the myrouter.local interface. With the help of the check method you don’t have to visit the support website for downloading the latest firmware for the range extender.
