ASUS released a stock firmware update that updated the NVRAM to access 64KB of memory.

Until recently, the stock firmware only accessed the first 32KB. In my case, my router (ASUS RT-N66U) has 128KB of NVRAM. Therefore, if you upload 64KB firmware to a router with only 32KB of NVRAM, the router will attempt to boot up expecting to see 64KB, only to find 32KB and ultimately crash before it boots or simply wipe out your settings.

If you don’t have enough space for those settings, or you run out of space in the future, your router will crash and require a factory reset. If you clear the NVRAM, you clear your settings. NVRAM is where the router settings are stored. It initializes the hardware first, then transfers control to the Linux kernel which boots the actual firmware.

NVRAM is the first piece of code that runs when the unit is powered on.

Stock firmware from the manufacturer can also upgrade the NVRAM (Non-Volatile Random Access Memory) whereas, custom 3rd party firmware does not. Why should I upgrade the factory firmware first? In the meantime, indulge me for a moment while I explain the importance of upgrading your factory firmware first. This can be done using method #1 which is accomplished from within the administration panel. Prior to flashing your router with custom firmware for the first time, it’s a good idea to first, upgrade the most recent factory default firmware. In short, here’s what the TFTP process looks like: What a mouthful! Huh? Don’t lose heart, my friend. Method #2 uses a technology known as Trivial File Transfer Protocol (TFTP). When changing to a different type of firmware, method #2 is the preferred option.

Method #1 is typically used for factory firmware upgrades or upgrades from the same type of firmware.

In this case, the software communicates with the router directly from your computer. How is firmware flashed to the router?įirmware can be flashed two different ways: (1) by upgrading the firmware from inside of the routers administration panel, or (2) using a client software application to upload the firmware to the router. The term “flashing” is derived from the method if installing software to the routers flash memory chip. Since routers don’t have hard drives like computers, they use small chips called flash memory. Use Broadcom routers only! What is the difference between flashing a router and installing firmware?Įssentially, they mean the same thing. If you have a router with ‘Atheros’ or Qualcomm’ chip, do not try to flash your router with Tomato firmware or you will most certainly ruin the device. The other big players are ‘Atheros’ and ‘Qualcomm’. Most open-source firmware is designed to work with Broadcom chips. You should know that not all routers are compatible with open-source firmware so you’ll need to verify compatibility before attempting to flash (install) it.

Set MAC address filtering to block devices not authorized to connect to your network.

Configure a VPN (Virtual Private Network) for remote access when you’re away.

Built-in support for USB (for file sharing).

Depending on which version you install, here are just some of the things you can do with Tomato: Tomato firmware can enhance the capabilities of your router and increase control over your network including: remote access, security and monitoring capabilities. Router hardware / firmware What are the benefits of running Tomato firmware? But on a router, its layered something like this: The Operating system (Windows, Linux, etc.) is installed above the BIOS level. Your computer has a BIOS hardware chip with BIOS software stored to CMOS (memory). The relationship of the hardware to firmware environment is similar to how your computer is designed. For those of you unfamiliar with Broadcom, they build computer chips for communication devices such as wireless routers. Since firmware needs a place to exist, it is installed over the Common Firmware Environment (CFE) on Broadcom-based routers. But if you want a better experience with more control, you might consider upgrading your router with Tomato firmware. Factory router firmware is fine if you just want to access the Internet with one or two computers. Your router is shipped from the manufacturer with default factory firmware. Think of firmware as “software for your router.” Devices like optical drives, network cards, routers, and printers all have software that is programmed into special memory contained within the hardware itself. Tomato Firmware is software that is embedded into a piece of hardware.
