Can you plug in a wired blue ray player in to the shaw gateway?
Unfortunately the Gateway doesn't allow you to use it as a "pass through" device to connect other devices. You would need to plug your Gateway and Bluray separately to your TV.
Newer TVs have multiple HDMI ports. If you don't have enough HDMI ports, you always have the option to connect the Gateway to the TV by component cable (red/green/blue) as well.
No, the Portal's network ports can't be used for internet.
