I am having some problems with my communications between my Xbox 360, My Tivos, and my PC. Seems to be that I am having a problem with these devices communicating together. All devices can get to the internet and can communicate if I plug in to a old hub. When these devices are plugged in to the SRW224G4P switch, I have only limited conecttivity with each other. For example the tivos cannot share media with the pc, but can share with each other. With no changes made to either device, I just have to move the network connections to a hub and everything works. The same is true with the Xbox 360. Internet works for all, no matter what device. Any help would be great. I have done everything I know. I have to keep this switch cause of VLANs for my home office.
