For mine it only says Model No. WRT54G...I guess it's V1 then. TY Edit: I just checked the installation disc and it says 1.05, so i think thats another way of finding the version #. The manual says "The file should be named hyperwrt*.bin, where * is the version number" so do i name the file "hyperwrt1.05.bin" or "hyperwrt1.bin"?
