Hi All, Forgive my ignorance as I seem to have some difficulty understanding networking & need some advice & help. Currently, in my room upstairs, I have my own telephone line & internet. There is also another telephone line & internet connection from another provider for the rest of the house (I am in the UK). In my room, there is a modem/router that is connected to a Time Capsule & I do wireless Back-Ups to this from my Macbook Pro. I will soon be getting rid of this dedicated telephone line & internet connection in my room & use the one the rest of the house uses but the issue here is that the Router is located downstairs connected to the telephone master socket. I need to be able to connect my TC to this Router to maintain my current Back-Ups & continue Backing Up wirelessly but wish to still keep the TC in my room upstairs. Very important - I must be able to connect things in such a way that everything stays the same with regards to the Time Capsule, Time Machine & currently Assigned/Named Wifi Accounts without losing any data & which will continue to allow me to do wireless back ups in sequence where they left off. I cannot run hard wired Ethernet Cables throughout the house so will have to rely on Power-Line Plugs (PLP’s) - I have just got some TP-Link 1200Mbps ones with 3 Ports but they do not transmit any WiFi. I wish to connect the TC to these PLP’s in my room as well some other equipment that I currently have & also allow for the devices I will soon be getting & for some extra spare ports for any future needs. I know I will need extra ports & have read on a few reviews that have stated to gain such, all one has to do is connect a multi-port ethernet switch but I do not know if that means the speed/performance will decrease in relation to the number of ports & devices being used or if it stays at maximum to all devices regardless of how many ports are being used. As I have no real understanding on how best to set up & connect everything and what to use, I have just taken a novice approach in what I *assume* might be the sort of thing to do but not sure if it is even remotely correct or would work well in reality. I have attached 3 images below labelled A, B & C as examples in an effort to convey what I am trying to achieve but seek advice on whether I am on the right path or not & how it should ideally be done. I just chose the connection ports & paths at random so have no idea if what is shown on the attachments is correct as I am not clued up on which ports to use with which devices & in what order etc. You will notice on the images, that on the TC, 3 of it’s ports are free - that is only because I did not know what I should connect there if anything. I would be extremely grateful if anyone could guide me on how best to set everything up, what to connect where & what options to use - 1) two or more 3 Port PLP's, 2) One 3-Port PLP & an Ethernet Switch 3) One 3-Port PLP & two Ethernet Switches etc. I think I read there are different types of Switches so would need to ensure I get the ones that work properly & automatically with everything when finally set up - are there any in particular I should look for? If my thought processes are completely wrong, then please very kindly inform me of the correct way to do everything! Many Kind Thanks! Bazzy!
