DISCUSS: Wireless Networking for Home Theaters
Reader 'das22' recently asked for help getting his two DVRs and a Sony PS3 connected to a wireless home network. Purchasing a wireless Ethernet bridge for each piece of equipment is one option, but that's relatively expensive. On our message board we've offered him an alternative. Can you think of any better way? Discuss - Wireless Networking for Home Entertainment Gear

I have this wired/wireless setup you describe. Previously, with wired router only all my computers could find each other “automatically.” Now the wired computers cannot find the ones on the wireless router and vise versa. I feel I’m missing something obvious…answered with your “network isolation” comment.
