I have a Linksys E5600 but couldn't find any documentation about support for this device. I tried to open the router but couldn't even get it dissembled. It seems they didn't even want people to open the device. Any lead in this direction will be appreciated.
I do have experience in porting OpenWRT. I can volunteer to add support for this device. But at least if someone has been successful in opening the router to access it's PCB, it will be really helpful.
