Hello
I have a simple wired network at home with a central 8 port 1Gb switch/hub Netgear.
Everything can see and ping (almost) everything else on the network.
However very occasionally the ethernet goes down. This is a very weird issue, as all devices are powered on, and how is it possible I cannot ping my printers, or other devices since they are all wired?
After months of tracing the issue, today I have discovered that simply switching the Virgin Broadband router on, or simply plugging it in to the switch, brings the ethernet down. As soon as I unplug it or switch it off, the ethernet comes back to life. I have tested two ethernet leads between the Virgin router and the switch and it is not a dodgy cable.
Therefore the Virgin router does something to "block" the central switch. But only very occasionally. For example this morning the issue started when I switched everything off, and then back on again. I traced the issue, satisfied myself that it is the Virgin router that causes it, and then after 3-4 tries of switching the Viorgin router on and off, it now works OK again. It may stay like this for weeks, months or it may cause "spikes", who knows.
I am not sure how the (Netgear) switch operates, but if, say, port 1 wants to talk to port 2, how would port 8 (the virgin router) prevent it? The lights on the ethernet sockets are on, there is no indication that plugging in the virgin router or switching it off/on somehow "fries" the switch.
Of course in the beginning I suspected the switch, so I switched it off and on to no avail. But I remember that in the past I was using other brands, an Edimax and another, and even then I was getting similar issues.
Any ideas?
