Updating the firmware is a delicate process. To ensure success and prevent damage to your router, it's critical to follow each step carefully.
Always connect your computer to the router using an Ethernet cable. Do not attempt a firmware update over Wi-Fi, as a temporary wireless drop will corrupt the installation.
Warning: Installing firmware meant for Hardware Version T1 onto a Version U1 router will break the device. Step 2: Download the Official Firmware Go to your regional official D-Link support website. Search for "DSL-124".
Bugs in older code can cause the router to randomly reboot or drop wireless connections.
