Good afternoon, I have a strange issue at one of my sites.  Occasionally users on older Mac's cannot get on the network.  Their computers connect, but no IP address is assigned and they eventually give themselves the 169. address. I use a Windows laptop and had no issues connecting on the WiFi. I contacted Meraki support, the tech claimed that the machine I was trying to connect from was not seen in his packet capture (he was looking this up via the MAC address of the Macintosh I was connecting from.)  DHCP is handled by a Windows server, and this was tested and functioning properly.  We tried connecting to the guest network which uses the MR33 as the DHCP server, same issue.  I then tried creating a new guest network and the client could connect.  Now the strange part is, if I reboot the MR33 everything will work fine for a few weeks without issue.  Also note there are two MR33's, only one so far seems to have this issue, but I still need to swap the access points to confirm this. Also firmware is up to date.  Any suggestions would be greatly welcomed, thank you for your help, Jon ... View more
