Re: Mac filtering I know how to do it but the named device is not recognised since I got the Hub 5? Mac filtering I have the new Hub 5 and have set up my wireless network and when I went to set up Mac filtering as I don't want my kids watching TV all night, I click on the radio button beside the device and every time it tells me the device name is not valid. I have tried every device. I have tried renaming the devices. Any ideas please?
