Have just purchased a Netgear N300 wifi extender and am having problems with the wifi button on my virgin super hub. I can't get it to flash blue/red to marry the hub with the extender. Have held the button in for 2/3 seconds but nothing happens. Have also tried holding it in for longer but it switches the wifi off. Have has this hub for a number of years and am wondering if its faulty. Have also tried rebooting it without result
It may be that WPS is disabled in the hub's menu, if you access the wireless settings via the hub's configuration page you can check to make sure WPS is enabled and then this should activate the button for you?
