Devices with Broadcom WiFi chipsets have limited OpenWrt supportability (due to limited FLOSS driver availability for Broadcom chips). Consider this when choosing a device to buy, or when deciding to flash OpenWrt on your device because it is listed as supported. See Broadcom WiFi for details.

FIXME The instructions below are for Broadcom devices and only serve as an example.
Remove / modify them if they do not apply to this particular device!

This section deals with

  • How you install OpenWrt from a device freshly opened
  • The steps required such as reset to factory defaults if the device has already been configured

Note: Reset router to factory defaults if it has been previously configured.

  • Browse to
  • Upload .chk file to router on upgrade page of R6250 web administration portal
  • Wait for it to reboot
  • Telnet to and set a root password, or browse to if LuCI is installed.
