Switching from 1.9.3.6 to 1.9.2.7-7b ??

Hi,

I think I'm going to try the custom firmware on my WL-300g AP - there are some nice tools (AsusMon) that need stuff like Telnet that the ASUS firmware doesn't support ...

Anything I have to be careful for when I switch from 1.9.3.6 to 1.9.2.7-7b ?
If something goes wrong can I switch back easily ?

thanks in advance !

sure, but why would you switch back to that?? olegs is best :D
