Accessing networked printer from AP or Router but not both

Can't figure out why I can print to printer from my upstairs laptop, but not from my downstairs PC, when both computers and the printer are on the same wireless network (same SSID, same security) consisting of wireless router downstairs (channel 6), hard wired to Access Point upstairs (channel 1).

Downstairs Set Up (Belkin F9K1002)
- DCHP on 192,.168.2.11 to 192.168.2.100
- LAN IP 192.168.2.1
- Gateway 192.168.0.1

Upstairs Set Up (D-Link DIR 505 in AP mode)
- DCHP off
- static LAN IP 192.168.2.10
- Gateway 192.168.2.1

Printer (Samsung SCX-4623FW)
- static IP 192.168.2.6
- gateway 102.168.2.1

When the printer connects through the strong signal of the DLink upstairs, I can print from the upstairs PC which is also connected via the DLink, but not from the downstairs laptop. When I turn off the DLink, and upstairs printer, laptop and downstairs PC all connect thru the Belkin, albeit with a weak and intermittent signal, I can print from both laptop and PC

So it seems that the downstairs laptop connecting through the Belkin downstairs can't see the printer upstairs when IT is connected through the DLink upstairs.

Probably a pilot error as I'm a networking novice. Anyone see my mistake?
