No. Tell us about your internet access. Cable, DSL or cellular, Wifi or ethernet, Router make and model, speed IP address provided by your ISP ( in the Network page of the router's info.) etc. How many people use your router? There was another poster on the forum with a similar sounding problem. He lived somewhere with a shared router provided by his landlord. Rebooting/resetting the router worked for him.
Does your system work fine in the early morning and get start to fail later?
I am guessing you have the same problem as me.
I live on the end of an 8km copper wire. At best, my download speed is 2.5 mb/s. My own theory is that the various corporations send off all there finished materials, whilst they are away from the office (Faxes; corporate Email..etc) and the line just gets plain overused. I have found that, on most occasions, switching the router on and off a few times, seems to trigger the local server that I am still here.
