Hi folks, I recently switched to Sky Broadband Unlimited from Pipex since they added their LLU product to my local exchange and using my Master phone socket downstairs, I can get about 11-11.5Mbps broadband which is a huge improvement over the old 5.5Mbps with Pipex. The Sky Router though, only has 2 10/100 ports which is a real downer, and to my knowledge nobody's figured out yet how to get your sky username out of the router's settings yet so that we can use our own routers, as Sky don't provide the log in details for the actual ADSL connection. So I decided to stick with the Sky router for now, and as my 2 PC's and CCTV DVR are located upstairs where the old Netgear DG834G Router used to be, I bought 2 of the TP-Link TL-WN821N Wireless N 300Mbps Wireless USB Adapters and one TP-Link 5 Port 1Gbps Switch (TL-SG1005D) from Overclockers UK. I have the Wireless USB adapters working fine and am getting my 11Mbps broadband quite happily, but today linked my 2 PC's together via the built-in LAN connectors to the 1Gbps switch upstairs. I'm using Windows 7 64bit Home Premium on both PC's. The internet is fine, through the USB adapters, but both PC's are still seeing each other through the Homegroup via the Wireless USB adapters and Sky Router, where as I want the USB adapters to provide internet access and use the Gigabit switch to connect the PC's together for big file transfers. How do I go about forcing the PC's to talk to each other via the 1Gbps switch, but use their wireless USB adapters for the broadband internet? My thanks if you can help, I thought there would be lots of guides on adding a switch to wireless network by now as so many routers still don't yet have 1Gbps built-in switches.
