I searched the forum but did not find anything obvious discussing the many options for Network Authentication and WPA Algorithms. In particular, why combinations are allowed of different authentications or different algorithms on the same radio. I use WPA2 & AES on both, and that works, but I wonder what the combinations allow.

Right, but I wondered why DD-WRT allows mixing of the settings? The Wireless Security tab has checkboxes, where you can select more than one. Why? I expected radio buttons where only one in each column would be allowed.

Settings being visible in the webUI doesn't mean DD-WRT allows mixing of incompatible settings; although, I think incompatible settings shouldn't be visible in the webUI to avoid confusion. Cool

Okay, thanks. I did not think there was any way the choices could be mixed. I think that is a minor UI bug that allows multiple check marks to be selected. There should be a clearing of the not selected checked boxes when a check box is clicked.
