Thanks again for your reply Have you been able to notice a difference between those users who don't get an address and those that never have the problem? Nope, there is no pattern at all with the users, very strange. Are all the WiFi users on the same VLAN? All the users are on the same VLAN for wireless clients. Has anything changed as far as the DHCP options are concerned on the VLAN(s), or firewall permissions? From the information I have from the third party nothing has changed as far as DHCP is concerned and the scope is good. Anything changed with respect to 802.11w or r - that might explain why some users are OK? Hmmmm, could look at this one. Have just created another heat map to see if anything shows on that and the coverage is good. Will keep an eye out since the newly installed was removed. Thanks John
