We added 22 access points to existing network. Setup is like this : 10 ap's are part of vlan 80 in building-1 Remaining 12 ap's part of vlan 81 in building-2 Users connecting to ap's ( vlan 80 )should get IP from vlan 90 Users connecting to ap's (vlan 81) should get IP from vlan 91 Now the issue is when we are in building-1 end user is getting IP , when he is moving to building 2 user not getting IP, but few users at building-2 are getting IP. As a resolution I have done the below: Grouped building-1 ap's and users in a single vlan 80 Grouped building-2 ap's and users in a single vlan 81 Now it seems to be better , but not sure is this correct resolution can anyone guide me.
