Upgrading to lancre

ggmartins edited this page · 7 revisions

This page explains how you can upgrade your current BISmark router running the 'klatch' or 'quirm' firmware to the new BISmark firmware release, codenamed 'lancre'.

Is your BISmark router running a previous firmware release ('klatch' or 'quirm')?

If you received a BISmark router from Georgia Tech or flashed your own router with our firmware between September 2011 and Novermber 2013, then you are running the 'klatch' or 'quirm' release. To confirm this, please go to your router's web page ( by default), click on the "Configure your Router" link, and log in with your credentials. Navigate to the "Status" section. If you see that the kernel version is 2.6 then you are confirmed to be running the 'klatch' or 'quirm'.

How to upgrade to the new BISmark firmare release ('lancre')

There are two approaches to upgrading your router with the latest BISmark firmware (both are described in more detail below):

  1. The upgrade can be performed remotely by the BISmark team
  2. You can perform the upgrade yourself

Please note that upgrading the router takes time and will require reconfiguring your settings afterward. Please do not begin the upgrade process unless you have at least 30 minutes of spare time. If you would like to upgrade and keep your settings, please let us know at and we'll gladly schedule a remote upgrade for you.

Remote upgrade by the BISmark team

The BISmark team is happy to upgrade your router remotely. If you'd like us to, please contact us at, and we can schedule a time to perform the upgrade when you are not using your home network/Internet.

Remote upgrades are generally safe and fast, but there is a small chance that the upgrade could unexpectedly fail. As such we ask that you schedule your upgrade at a time when you do not have a pressing need for Internet connectivity, and that you be reachable via telephone at the scheduled upgrade time.

Upgrading your BISmark router on your own

If you want to upgrade your BISmark router yourself, please follow these instructions:

  1. Download one of the following images, depending on the model of the Netgear/TP-Link router running BISmark:
  2. Navigate to your BISmark router's web page (i.e., click on "Configure your Router", and log into the configuration application.
  3. Click on the "System" tab and then click on "Flash Firmware".
  4. Click on the "Choose File" or "Browse" button and select the file you downloaded in step 1.
  5. Clear the "Keep configuration files" checkbox.
    • Warning: this will delete all the saved settings on your router. Be sure you're ready to reconfigure your router afterwards. If you do not want to lose your settings, stop now. Please contact us at and we'll schedule a remote upgrade for you.
  6. Click on the "Upload Image" button. This will begin the upgrade process. Do not interrupt the upgrade process.
  7. Wait least 10 minutes for the upgrade process to finish. The router LEDs will begin flashing after a few minutes. This means that the router has uploaded the image and is rebooting. Rebooting will take another few minutes.
  8. Once the power LED is steady green, the upgrade is complete.
  9. If the wireless radios do not power on (blue and green 5 GHz and 2.4 GHz LEDs are not lit on the front panel) on startup, press the wireless button on the router. If this does not help, reboot the router and the radios will power up.
  10. Register your router. If your router connected to the Internet automatically (it got a DHCP address automatically from your modem or your ISP), then you will get a "Register your BISmark router" page when you try to browse the web. Please follow instructions carefully to register your router with us. If your router needs to be configured to connect to the Internet first, please configure it (instructions for logging in are in step 11) and come back to this step. If you already have registered with us previously you can sign in with your account, but please "Validate your Registration" after you sign in.
  11. Reconfigure your router.

    1. Start by visiting You can access the router configuration page by clicking the "Configure your router" link. The default username and password are:

      Username: root

      Password: bismark123

    2. You should change this password as soon as is practical by navigating to "System" > "Administration" in the configuration application.

    3. You should also change the passwords on the wireless network. Remember to change passwords on both the 2.4 GHz and 5 GHz radio interfaces ("radio0" and "radio1" under "Network" > "Wifi" in the configuration application).

    4. After making any configuration changes, be sure to click "Save & Apply" at the bottom of the screen to ensure your changes take effect.

The router upgrade process is generally reliable. However, if the router upgrade fails for some reason and you can no longer access the router, you will need to perform a low-level install.
