If your on vlan 100 it works but if your not on vlan 100 it doesn't? Then routing is not working. From the AP or the laptop on vlan 100, you can ping vlan 100 gateway correct but nothing else. If so, check your routing.
The BVI interface is what needs an IP address. If a laptop in an access port vlan 100 on the same switch can't ping the gateway or other gateways, then you have a routing issue or vlan 100 is not being passed to the core.
how can i check if vlan 100 is pass to the core or not ? I think i did a test before by puting a laptop on vlan 100 and another laptop on another vlan 200, the laptop on vlan 200 is able to ping the laptop on vlan 100 but not the access point (need to re-confirm)
Need to makes sure vlan 100 is defined on all the switches that lead back to the core. If you can ping the AP from a laptop on vlan 100 on the same switch then nothing is wrong with the AP since that is layer 2. Layer 3 seems to be broke.
