I have searched for and found a variety of firmwares for my WRT54G and want to try them all however I am a bit concerned that once I go with Sveasoft, for example I will not be able to try out HyperWRT, or viceversa. What have you all found about switching firmwares? Once I flash it to something not linksys firmware am I doomed to that firmware alone? Can I go back to the Linksys firmware if I happen on any stability issues? Thanks in advance!
