switch

I have RoadRunner Internet cable service hooked to a Motorola Surfboard modem. This is connected to a 10/100 wireless router (located in the garage).

Downstairs, I have a ZyXEL GS-108b gigabit switch connected to one port on the router. From this switch I ran connections to a PS3, DVR, Vonage box and a wireless router (Buffalo AirStation 10/100). The Buffalo AirStation works as a wireless AP for other laptops, iPads and cell phones.

Upstairs, I have an Asus gigabit switch connected to a gaming desktop, printer, and a media server on FreeNAS (PS3 Media Server on FreeNAS). The router is configured to assign static IPs to both the PS3 and the media server.

Problem - I connect a laptop to the switch downstairs after disabling the wireless, thus making sure that I am accessing internet through the wired connection (and the router in the garage). All my computers, iPads and cell phones are able to connect to the internet without a problem.

My PS3 connects to the interent with a wired connection but is unable to access the media server (I get a message that no media server is found). I used a wired laptop downstairs (connected to switch downstairs) but am unable to ping either the PS3 or media server!

I may be doing something silly but am at my wits' end. Please help!

Just wondering if anyone has experience with the cisco 2911 or 2900 series routers. I understand it is newer and similar to the 2811 but more robust. The price difference is not that much more.
