I have a script that changes a password on one of my wireless networks so that it can be controlled independently of the main administration portal. It used to a work on DD-WRT, but not TomatoUSB. Here's the procedure the script follows: nvram set wl0.1_wpa_psk=$PASSWORD nvram set wl1.1_wpa_psk=$PASSWORD nvram commit service wireless restart The new password is reflected in the tomatousb administration portal, but guests are unable to connect to the network (they receive a message about the WPA key not matching). Simply saving the configuration in the tomatousb portal is enough to make this work. I've tried things like wl down/up and rebooting the device to no avail.
