I built my own LAN, and learned to administrate, but have no clue as to the how or why of it. The nuts ‘n bolts are P.F.M. Furthermore, there are homotrons running amok that have caused a glitch. At around prime time each day the Internet goes down. The computers still talk to each other but for some reason the email stops and most web sites become inaccessible. A cry of disgust will ring out from some corner of the house and I become Nick Burns, Office Computer Guy, taking full blame. There are so many possibilities, and I have no diagnostic means. Is it my ISP — somehow detecting excessive usage and blocking ports? Some kind of incompatibility between firewall, spybot software, ad blocker, or antivirus? S’mans online game, (quirky resource hog) Everquest ? The cable modem? Network Router? I’ve tried to sleuth the system by isolating PCs, rebooting, cycling power to the hardware and have learned nothing. Until yesterday when the trail turned hot. I’ve got it figured out that task scheduler allows Microsoft’s Windows Update to phone home once each day. Just happened to coincide with yesterday’s internet freeze. Could this be? Anybody? Anybody? Beuhler?
