first of all put that CD back in the box and uninstall anything if may of installed on your system.
Secondly link your computer to the routers via one of the LAN ports. put this into your web browser address bar
hit enter and login, the default login for both username and password is admin
once logged in find QUICK SETUP and click on it and proceed (press next)
WAN Connection type - for VM its Dynamic IP but the auto function should be fine
setup your wireless security, password. click on WPA-PSK/WPA2-PSK then create your own wireless password. you can change your wireless networks name here by changing whats written in the SSID box.
your region is UK so change it if its set to anything else. wireless channels will range from 1-13. you can download inSSIDer
onto a wireless capable device/Microsoft operated laptop or wifi analyizer onto a phone from the app store. scan your area for wireless networks and note which channel each uses. then set your wireless network to use a channel that isn't in use.
then click finish to end the quick install process and then reboot.
once the router comes live again power it down manually via power socket. power down your SH and link an ethernet cable to the SHs ethernet port closest to the white cable port to the routers WAN port then power up both.
