Upgrading the OpenWRT version on WRT54G nr. 2

  1. We connect a PC to one of the LAN jacks of the WRT54G. The WAN jacks is connected to our gateway.

  2. The latest OpenWRT version at the time of writing is backfire 10.03, and according to the docs on flashing the device, we should pick an image according to chipset and clock frequency.
