    I have two question, would be great to even get one answer :)

    I have a plug into the mains network, but I need to connect more than one RJ45 cable to it. What is the best way to do this?

    Also, could I somehow connect a wi-fi extension to the plug in unit?

    Any feedback would be great :)

    Add an ethernet switch.

    If by "wi-fi extension" you mean a wireless access point (WAP) the answer is yes (it connects by an ethernet cable).

    If you don't have a router in your network and want to have multiple devices with internet access at the same time then I suggest you use a wireless router instead of an ethernet switch and/or WAP. If you already have a router then I suggest you add a wireless router, but use it only as an ethernet switch and WAP, as follows.

    JohnWill's procedure (Aug. 30, 2008) for configuring a secondary router as a switch and, optionally, wireless access point follows.

    Connecting two (or more) SOHO broadband routers together.

    Note: The "primary" router can be an actual router, a software gateway like Microsoft Internet Connection Sharing, or a server connection that has the capability to supply more than one IP address using DHCP server capability. No changes are made to the primary "router" configuration.

    Configure the IP address of the secondary router(s) to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses 192.168.0.2 through 192.168.0.100, I'd assign the secondary router 192.168.0.254 as it's IP address, 192.168.0.253 for another router, etc.

    Note: Do this first, as you will have to reboot the computer to connect to the router again for the remaining changes.

    Disable the DHCP server in the secondary router.

    Setup the wireless section just the way you would if it was the primary router, channels, encryption, etc.

    Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. [You will not need a cross-over cable if one of the "routers" is a computer.] Leave the WAN port unconnected!

    This procedure bypasses the routing function (NAT layer) and configures the router as a switch (or wireless access point for wireless routers).

    For reference, here's a link to a Typical example config using a Netgear router
