AP Isolation

1rst can't route to the ip. I have an i termal address  of 192.168.2.X and the the gateway gives me  192.168.12.X there is no way to route and i can't ping to any of the devices on the wifi.

2nd i have a network fax that uses wifi which connects and a separated scanner and none of the devices can see each other on wifi
