Hi All, Setup as follows: Thomson Speedtouch 585 on 192.168.1.254 PC w/ Windows 7 wired on .72 Laptop w/ Windows 7 wireless on .66 Xbox 360 wired on .64 iPhone wireless on .68 Internet works fine on all devices. Have got the 360 set up using the PC as Media Center which is working fine and streaming content from the PC no problem. What I cannot do is browse the computers shared folders from outside the Media Center. The laptop and the PC also don't appear to be able to communicate with each other. Shares don't get picked up and they cannot ping each other. In fact I cannot ping any node on the network from any other node. All nodes can ping the router no problem. I have disabled windows firewall on all devices and have even disabled the outward facing firewall on the router to no avail. I have tried resetting both the winsock entries and the tcp/ip stack as well but this did not work either. Both the PC and the Laptop have AVG free installed. I have a feeling the problem may lie with the router as it is new and I have not had this problem in the past but I want to exhaust all other options before I shell out for a new one. Does anyone have any advice?
