Hello - We are using a 2960 XR as DHCP server for our guest wireless network and recently increase our scope because we were running out of ip addresses. After doing this we began receiving the above message and users are complaining of sluggish internet perfomrace. I have read about changing the SDM template but it seems this is related to routing. We are using this switch only as DHCP server and are not routing at all. My question is if I change the SDM template to "SDM prefer VLAN" would that help my issue? This would be only temporary until we get a more permanent solution. Thanks in advance. Frank
