IP issues

We have ran out of IP’s for our wireless network down here in the resident halls.  Students can connect to the SSID but do not receive IP’s.  This is generally happening after hours from 9pm to 1am.  Paul has requested more IP’s so I am hoping we get them soon.  We added wireless to all the resident halls this summer and we did not anticipate the full magnitude of the number of devices the residents would bring that used wireless.  More students are using wireless laptops than ever before, they are also using smartphones in greater numbers.
