And even if the router has auto-update, check every now and then to make sure it is actually working, and the router firmware is up-to-date. If your router manufacturer hasn't released any updates to the firmware in the past 3-5 years, consider upgrading to a "newer" router

Firmware is the term for the software that runs on your router. Because after all, a router is also a computer. Like any software, firmware can have bugs, and it is occasionally updated. However, updating your router's firmware is a bit different than updating your computer's software. Follow the instructions below to update your router's firmware. They are easy to follow.

Before you start, you must determine which version of firmware your router is currently running. To do that, you must log in to your router. RouterCheck can give you detailed instructions for logging in to your router.

Visit the router vendor's website to investigate downloading newer firmware. Look through the download section for your router model to determine the latest firmware version. Click here for the vendor's support site, where you can download firmware.

If your router is already running the latest firmware, you do not need to do anything else. If not, then download the latest firmware version to your computer. Ensure that you download the exact firmware that your router needs. Important: The firmware must exactly match the router model. In addition, the router models often also have revision numbers that must match.

Return to your router's interface in the browser window that you opened previously. Open to the administrator page and see how to update the router's firmware. Typically, this will be an edit box with a browser button that enables you to select the firmware image that you want to update. Select the firmware that you just downloaded and start the process.

If you have done everything correctly up until now, the new firmware should be loading into your router. Do not turn off the power to your router until the process is complete. Perhaps it's time for a break. Take your mind off of routers and sing a little song. We recommend G.T.O. by Ronny & The Daytonas. It's about the right length of time for a router update.

Type 1/2/3 indicates if it can be rooted directly. For Type 2 only, Root Strategy # indicates how to do it. Please, don't miss these important details whenever you add a new firmware version to this page if you know about that.

The stock bootloader allows TFTP flashing only with the correct RBI firmware file for the hardware version, usually identified with a board mnemonic string like XXXX-X. HAving an RBI file for your Gateway board is therefore really important.

The Firmware filename combination is usually ISP specific, so the first thing to do is to find another known firmware from the same ISP to get a better idea of how it should look like. As you can see from below links, it is often constructed by combining some tokens like product vendor, product name, hardware version, firmware version and special ISP-specific suffixes or prefixes.

The ISP may have customized firmware version numbers to match their own versioning scheme. If so, check the contents of /rom/etc/config/versioncusto. Look for any firmware version prefiz, suffic, or complete string overrides.

Firmware partitions, called banks, contain signed and read-only squashfs images that get extracted from RBI files during regular firmware flash or upgrade. These images cannot boot on different boards and do not include any sensitive info about your own device so they are totally safe to be shared.

The second file is used to update the DD-WRT web interface. It can only be installed when the first file is uploaded and successfully used to flash your router. This file is usually in the format XXX-webflash.bin.This file is typically uploaded from within the DD-WRT web interface from Administration > Upgrade firmware page.

The board variant as well as basic info such as firmware version, bootloader, etc can be accessed via the web interface of the stock firmware, which is usually at 192.168.1.1 or 192.168.1.254 and which is branded by the provider. There are no management protocols available (e.g. telnet/ssh) other than the web UI.

Credits: this whole bootloader upgrade procedure is the result of the hard work done by some members of an Italian user community (Link1, Link2, Link3) that released this information to unlock the original firmware. It has been adapted to flash a working CFE image by integrating that information with what's currently available on the OpenWrt forum thread about TG582n

If you haven't done it yet, download OpenWrt 15.05 Chaos Calmer A4001N image _calmer/15.05/brcm63xx/generic/openwrt-15.05-brcm63xx-generic-A4001N-squashfs-cfe.bin.Then connect to the CFE web interface, click browse and select openwrt-15.05-brcm63xx-generic-A4001N-squashfs-cfe.bin as firmware. Once you proceed, the flashing process starts and in few minutes your new openwrt-powered TG582n will come online. If you're monitoring the board with serial port, you'll see the process in details. The management IP address will be 192.168.1.1 (if your PC interface is still on 192.168.2.x you have to change it to 192.168.1.x - a DHCP server might be already running on OpenWrt so you might try to put it back to DHCP mode straight away).
