1) There is configuration for interface priority and there is configuration for WiFi in GUI and in CLI too with wificonfig tool, but you must read documentation. So start eg. here http://wikis.sun.com/display/OpenSolarisInfo200906/How+to+Check+the+Status+of+Your+Network+Connection
2) If your wifi is supported then you can see it and modify it. Then you can use dladm, ifconfig and wificonfig or GUI 3) It is if you have supported wifi. You can check support for your wifi here http://hub.opensolaris.org/bin/view/Community+Group+laptop/wireless and if you need support for newest HW then buy subscriptions from Sun or use dev version 4) http://www.catb.org/~esr/faqs/smart-questions.html -- This message posted from opensolaris.org
