Hi, I have just built an extension and installed a home cinema. I have a wifi router in my house and I am streaming HDMI signals using an Octavia distribution amp and receivers over pairs of cat6 cables. The problem is I have my router installed in my home office in one part of the house and connect to Ethernet for my work pc and wifi for my home pc and wifi for personal devices (ipad's phones etc.). However the signal does not extend to my new extension. The Octavia is installed with my cinema in an av cabinet along with a PS3 and Sky HD box and all linked via Ethernet & HDMI to a projector and amp. I don't have Ethernet running from my home office to the av centre albeit I do have a telephone line. So I cant connect my PS3 and sky box to the wifi as it doesn't reach. My thoughts are to either... 1. buy a repeater. 2. buy a better home hub (I have a bt hub) with stronger reach but I still cant connect my projector and av unit (unless I buy a wifi receiver). 3. run an Ethernet cable from the home hub to the av centre. If I go with 3 can I simply plug in another home hub to distribute the Ethernet to multiple devices or do I need to run multiple cat6 cables? I tried using plug in extenders but the extension has its own mains power supply and surprise surprise wont connect. Any ideas as I want network connection in my cinema room so I can control devices using a tablet etc.
