I installed Tomato v1.11 on my router and setup wpa2 personal security and was able to connect to it with my workstation using the psk. A week later I am able to connect to it with another workstation with no key; the network shows up as open with security not enabled. I disabled/enabled security, rebooted the router, still open. DD-WRT looks like it may offer better access control rules so I'll unload Tomato. It appears this version is older than what is offered on the tomato site. Can their latest versions be installed on this router or has the one available for download here been modified to work?
