I have my main router in the basement and a dlink dap-1360 access point on the second floor connected by ethernet. I've assigned a static ip to the access point. It shares the same SSID as my router, same encryption, same default gateway(192.168.2.1), same netmask (255.255.255.0). Any wired devices on my LAN can be seen regardless whether I'm on the AP or router.
The issue: any wireless clients (Airport Express base stations) that connect wirelessly to the AP cannot be seen if I am connected wirelessly to the router and vice versa. All my air port express stations are Static IP (one connects wirelessly to the router, the other to the Ap). By way of example, when I am in range of the router, I cannot ping the Airport Express wirelessly connected to the AP, and vice versa.
What am I doing wrong? How can I ensure wireless clients speaking with the AP are visible to devices connected to the router, and vice versa.
