Hello, I have a question about a network adapter I am about to purchase [ TRENDnet TPA-311 HomePNA 3.1 Coaxial Cable to Ethernet Adapter Up to 256MBPS Single Unit - TRENDnet - TPA-311 ]. I am concerned that it may not work the way I want it to however, my plan is to put this in my room so I can get a direct internet connection to my computer through the ethernet ports on the adapter. My internet provider is Shaw I have a coaxial cable which runs into my room which I believe internet and TV signals.
