|What you state in your post won't work. Those are two completely different subnets and they can't communicate with each other without adding a route in your router.|
Your AP should have been configured with an IP address within the same subnet as the router.
A typical detault router setup (using the router IP from above) would be the following:
LAN IP: 192.168.0.1
Subnet Mask: 255.255.255.0
DHCP Enabled = Yes
DHCP Scope = 192.168.0.100 to 192.168.0.199
Since your DHCP Scope runs from 100 to 199 and .1 is in use by the router, that leaves .2 through to .99 unused. I would recommend using .2 for the AP. So when you configure it, it should have the following TCP/IP settings:
IP Address: 192.168.0.2
Now it will be in the same subnet as the router and any computer connected to the router will be able to access the AP using it's LAN IP (192.168.0.2).
You may have to reset the AP to factory defaults and reconfigure it with the correct TCP/IP settings. Do so as per the manual.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
