Adding A Gigabit Switch
I have Sky broadband therefore I can't change router. The wireless on it won't reach downstairs for PS3 and Airport Express. I also now have a large amount of data in the form of music files on my desktop upstairs and a back up server and am thinking of putting some of my favourite tv series on hard disc so I can watch them around the house.
Due to the above I want a wired network. I'd like to achieve this by the use of home plugs and a switch. The router has 10/100 ports, so I want to plug a gigabit switch into it and then connect the desktop to the switch. I will also connect one home plug to the switch and then one downstairs to connect the PS3 and Airport. The PS3 (a fat one) I think has a 1000 port, the airport express only 10/100. My back up server has a 1000 port. The home plugs I want to use have 1000 ports.
My questions are -
1.) If everything is connected to switch, and then one connection from switch to router will the devices connected still be able to access internet through switch?
2.) Everything bar the Express has a 1000 port. If the Express is on will the whole network be limited to 10/100 or just the connection to the Express? If the Express is off will the network be 1000?
3.) I have two devices downstairs. When Sky start the Anytime+ streaming thing, I'll have three devices. Can I connect a switch to the downstairs home plug so all devices can be plugged in at once? (Again from question 2, I don't know the speed of the Sky ethernet port but if it is 10/100 will that slow whole network to that speed? The Sky box is on all the time unlike the Express)
