I typically see that 30-50% of devices which associate and get a DHCP lease from our wireless networks never log onto the portal and actually use the wireless connection... This apparently includes many devices which remain on campus (plugged in to charge?) overnight. (Our guest network does have a portal, it just doesn't do any stringent authentication...)

Even with a portal, don't devices still get a DHCP lease? We had to deal with this by making our subnet and DHCP scope large enough for any potential mobile devices automatically associating, even if they didn't have credentials for the portal. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at https://urldefense.proofpoint.com/v2/url?u=http-3A__www.educause.edu_groups_&d=AwIBAg&c=xoYdONxMEGxjdvKj5bOdEOV28uakaJ20R4TjadGGZBc&r=k9GuXUxBnq8dKeP-TM4_u3H9MTZhXcX7GvfnnTt9LsE&m=2_Cir644y4cMBCwXxQcx7Rt3mVqqL3a4WleO5Irbydw&s=8KpqnUqgYO06O8oZ9LJGYzz5eQHD2iyh81VRzcCRdew&e= . ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
