I would think so.

Hi
from you screen shot you have the AP in LAN 2 as 192.168.2.2 and the gateway set as the same.
there is no routing on the AP and you are telling the remote clients that the AP is the way out when its not.



If you look at this image about you would need a router attached to each switch as the gateway or you could connect something like a 2830 and use P1 for LAN A and P2 for LAN B.
Whatever address you gave the router on the LAN B side is what you would need as the default gateway on LAN B.
