no special hardware required, just read pdf from the zip in the openwrt link above. Yes, you need PC with parallel port, cable and the router.Originally Posted by Intelman
Yes, once you upgrade bootloader, you will then be able to use ANY ASUS WL-500g firmware including custom firmwares from this forum.Also, if this firmware works, and it works well, will it be periodically updated, or just a one time flash and thats what you got. Sorry for all the questions, but I like information that I dont know, and it may come to benefit me :P
You need to use JTAG only once to flash bootloader. The bootloader itself is able to flash ANY firmware. Once done - you will have everything.
