I have 2 windows 10 vs 1703 htpc's and 1 WHS2011 server. On adsl and using Linux could access all using any modem/router. On Monday I was changed to VDSL. Really pleased with massive speed increase. However using Fritzbox 7490 or the supplied HG669 I cant connect to them. They show up in modem under network but Linux computer wont find them. Windows 10 finds them okay. So have HG669 connected and deleted Linux and reinstalled Windows 10 so I can connect to my network. Why when on adsl I could connect but not on vdsl as these are on home network and don't want to access from internet. Fritzbox could connect on adsl but not vdsl and only settings changed for vdsl other settings untouched. I have to leave hg659 connected and not reboot for next 10 days from email Vodafone sent me last night as they optimize the line.
