Don't use this image on any other router - for WRH54G only !

Linksys WRH54G is now supported by dd-wrt. No need to replace cfe, but you alwayays need to use special firmware built for wrh54g only. Even for later GUI upgrades.

  1. Restore to defaults
  2. Open upgrade page, select dd-wrt.v24-12548_WRH54G_micro.bin (or other special wrh image)
  3. Upgrade
  4. When it comes back, be sure to press reset button for 5 s to restore dd-wrt's factory defaults
      • that's it ***
