This is probably trivial, but I can't figure out how to fix it. There is an asymmetry in the connectivity/visibility of the computers on my network. On the wired side (running through the DIR-655) I have a couple computers, a satellite box, and a NAS. Wirelessly, I have a laptop, an XBox, another satellite box and a few less important devices.
The devices on the wired network can see each other and can see the wireless devices (such as the laptop). However, the wireless devices cannot see any of the wired devices. This is particularly frustrating because I've got UPnP on the NAS and I'd like some of the wireless devices to be able to access it. I have UPnP turned on in the settings of the DIR-655, but broadly speaking it seems like something else is blocking communication and I can't figure out what it might be.
