I had my Fritzbox working and could access the control panel etc, but the next time I turned on the PC, I had no internet access and could not access the Fritzbox control panel at the IP address it was set to. The Fritzbox was still letting Voip through to my phone, but otherwise no other internet access. How do I find my Fritzbox if it is not showing up at the IP address it should be at? And how can it not allow internet access, but allow Voip to work? dg
