Hi, I just bought a WRT54GS V4 (with the intention to use OpenWRT) but I'm puzzeld about the firmware I have (and if it is still Linux based) According to the setup page it is v1.05.3 and SysInfo.htm reports Code: Vendor:LINKSYS ModelName:WRT54GSV4 Firmware Version:v1.05.3 , Sep 22 2005 #:001 Boot Version:v3.6.4 CodePattern:W54s Country:Europe However on this forum I also read that there exist 4.x.y.z. versions. Now I'm puzzeled. Does this sudden change of version mean that it is based on different hardware ? Another thing is that I can't find this versions firmware .bin, so if I manage to flash an older/newer version I cannot get back to my current version. Any hints ?
