Some firmware updates reset the router to factory defaults. You will need to re-enter your ISP username/password and your Wi-Fi network name (SSID) and password.

Before we delve into firmware specifics, let’s briefly recap the device. The D-Link DSL-124 is a wireless N300 ADSL2+ modem router designed for home and small office use. It combines a DSL modem, a router, a four-port Fast Ethernet switch, and a wireless access point into a single device. While it is an older unit (first released around 2013-2014), millions are still in active use, particularly in regions where VDSL and fiber are not yet ubiquitous. D-link Dsl-124 Firmware
The router integrates a stateful packet inspection (SPI) firewall, a feature that inspects incoming packets before they are allowed into the network. The built-in hacker attack logging helps protect against Denial of Service (DoS) attacks. Additionally, the device incorporates Quality of Service (QoS) features, which allow for priority queues to ensure a smooth network connection for specific groups of users or applications.
Download the latest firmware file, which typically ends in a .bin or .img extension. Some firmware updates reset the router to factory defaults
For years, the DSL-124 was a staple for small offices, offering speeds up to 24 Mbps and a suite of features like Stateful Packet Inspection (SPI). However, the firmware update process itself became a hurdle for many:
A: Strongly discouraged. A single Wi-Fi dropout during the 2-minute flash process will brick the router. Always use Ethernet. Before we delve into firmware specifics, let’s briefly
Click the Browse or Choose File button. Select the .bin firmware file you downloaded earlier.
Before downloading any firmware, you must check your router's specific hardware version. Installing firmware meant for a different hardware revision can permanently damage ("brick") your device. Turn your D-Link DSL-124 router upside down. Locate the white specification sticker on the bottom panel.
If you still wish to update your DSL-124's firmware, it is critical to follow the instructions precisely. Do not attempt to update over a wireless connection; you must use a computer connected via an Ethernet cable.
While updating the firmware is a relatively simple process, some issues may arise:
