I am reasonably computer proficient although networks flumux me a little. However, I believe I'm not the one at fault here. I have 1 PC, 1 old Mac (PPC) and a couple of laptops which I'd like to network to share files. I can do so succesfully within Windows/OSX for about an hour, and then the network seems to drop. Internet connectivity remains working, but I can no longer see other computers on my network, Windows Homegroup stops working and file sharing between my computers stops. If I power off and repower my router, all is well for another hour or so and then it repeats. Am I missing something? I don't see any obvious configurations in the Technicolour gateway settings. Help?
