Update D-Link BIOS Firmware
You can easily update your D-Link BIOS Firmware in a few simple steps. When we think of updating firmware in computers our bowels loosen and beads of sweat form on our brow. The general rule with a PC BIOS update is if it isn’t broken, don’t fix it. But in regards to a router, the update procedure is pretty easy as long as you get the correct version of firmware for your model. Upgrading your BIOS firmware will cause cause you to lose any information currently stored in the router. Make sure you have all of your ISP, DNS and other information written down in case you need it later. You will also need to know default passwords for the router, as the password will also be reverted to factory default when the update is complete.
Steps For Updating D-Link Router Firmware
It is critical that you get the exact model and revision number of your router in order to ensure you get the correct firmware. There will be a label somewhere on the router that states all of this information. Once you have it all written down do the following:
- Go to the D-Link website and download your Firmware from here.
- Once you save the firmware to your PC, go to your web browser and type in 192.168.0.1 and hit enter. You will need to login with the router username and password you provided during original setup. If you do not remember it, you can reset the router by depressing the red button on the back of the router. This will set the username to “admin” with a blank password.
- Click the Tools tab, and then the Firmware link or button off to the side.
- Click on the Browse button and navigate to the .bin file you downloaded earlier, then click OPEN.
- Once you click Apply, the firmware will begin updating. The entire process shouldn’t take more than a couple minutes.
You will need to make sure you are on a PC that is physically connected to the router. Otherwise, you will lose your connection when the firmware updates. Once complete, be sure to log in and change the admin password again, restore Wifi security setting and anything else that changed during the upgrade. It is important to keep the router updated, as there may be frequent updates that resolve security issues, or improve router functionality.

In IBM PC Compatible computers, the basic input/output system (BIOS)[1] , also known as the System BIOS, is a de facto standard defining a firmware interface.[2]
The BIOS of a PC software is built into the PC, and is the first code run by a PC when powered on ('boot firmware'). The primary function of the BIOS is to load and start an operating system. When the PC starts up, the first job for the BIOS is to initialize and identify system devices such as the video display card, keyboard and mouse, hard disk, CD/DVD drive and other hardware. The BIOS then locates software held on a peripheral device (designated as a 'boot device'), such as a hard disk or a CD, and loads and executes that software, giving it control of the PC.[3] This process is known as booting, or booting up, which is short for bootstrapping.
BIOS software is stored on a non-volatile, ROM chip built into the system, on the mother board and the BIOS software is specifically designed to work with the particular type of system in question including having a knowledge of the workings of various devices that make up the complementary chipset of the system. In modern computer systems, the BIOS chip's contents can be rewritten so allowing BIOS software to be upgraded.
A BIOS will also have a user interface (or UI for short). Typically this is a menu system accessed by pressing a certain key on the keyboard when the PC starts. In the BIOS UI, a user can configure hardware, set the system clock, enable or disable system components, and most importantly, select which devices are eligible to be a potential boot device and set various password prompts, most importantly a password for securing access to the BIOS UI functions itself and preventing malicious users from booting the system from unauthorized peripheral devices.
The BIOS provides a small library of basic input/output functions that to operate and control the peripherals such as the keyboard, text display functions and so forth, and these software library functions are callable by external software. In the IBM PC and AT, certain peripheral cards such as hard-drive controllers and video display adapters carried their own BIOS extension ROM, which provided additional functionality. Operating systems and executive software, designed to supersede this basic firmware functionality, will provide replacement software interfaces to applications.
The role of the BIOS has changed over time; today BIOS is a legacy system, superseded by the more complex Extensible Firmware Interface (EFI), but BIOS remains in widespread use, and EFI booting has only been supported in x86 Windows since 2008. BIOS is primarily associated with the 16-bit and 32-bit architecture eras (x86-32), while EFI is used for some 32-bit and most 64-bit architectures. Today BIOS is primarily used for booting a system, and for certain additional features such as power management (ACPI) and video initialization (in X.org), but otherwise is not used during the ordinary running of a system, while in early systems (particularly in the 16-bit era), BIOS was used for hardware access – operating systems (notably MS-DOS) would call the BIOS rather than directly accessing the hardware. In the 32-bit era and later, operating systems instead generally directly accessed the hardware using their own device drivers.
