Wired devices cannot see wireless devices

[the FooL]

Equipment:
Netgear WNDR3700v1 wireless gateway/switch.
Wireless connection: three laptops (Windows 7)
wired connections: two desktops (XP and Windows 7), 360, ps3, media player, av receiver.

When trying to use remote desktop from the laptop, it fails to find the computer.
Even when I try to use the IP address.
However, I can access them from between the desktops without a problem.

If I run a game on the local LAN on desktop 1, desktop 2 finds it, but neither laptops do.

Is there some trick in getting computers on the WLAN and the LAN to see each other?
Do I need another router that can support this?
It's as if certain packets between the WLAN and LAN networks aren't being shared.

Thanks.

According to the WNDR3700v1 manual, there's an ability to enable a guest wireless network. I'm wondering if your laptops are connected to that network and not the "regular" network.

check what IP address your wired vs wireless are getting...they may be on separate networks.

I believe I found the issue.
The WNDR3700 is my main router with only the 5.8GHz access point enabled.
I also have a DGL4300 (DLink) acting as an 802.11b and g (2.4GHz only) access point (DHCP disabled).

I enabled RIP on the WNDR3700 and marked it as my main router.
I also enabled it on the DGL4300 since the instructions didn't indicate if I had to do it only if it was the main router.

I had assumed my brother was on the 5.8GHz link, but nope, his laptop only does 2.4GHz.

So I learned something regarding RIP today.
Yay.
