This is from "E-Buyer" and is a 10/100M 4 port Broadband hub - Just plug your Broadband modem into it and then connect up to 4 computers for shared internet access - none of the other computers need to be switched on to do this.
I bought one to replace the second US Robotics router that packed up on me and it has been brilliant - easy set up, nice neat unit and an amazing price ! ( £21.14 inc. VAT + delivery ).
There is also a USB Print Server port for sharing a printer although I haven't tried using this.
