I've got a problem here at work which I will describe to you folks and see if any of you might have an idea about how I go about resolving it. I have a room which I call the Cursed Room.
It started with a printer which got moved from one side of the building to this room, suddenly it stopped responding completely to the network in its new home. I've been pulling my hair out trying to get that working. It will respond if I throw it on a little 5 port switch and plug my laptop into that switch. As soon as I plug the printer or the switch into the main network, the printer stops responding at all.
This room also has 1 of 3 wireless routers in it. On the weekend, they moved some stuff and suddenly the router stopped responding to http admin and pings, however it still works routing wireless data. So I come in this morning early to factory reset the router and reconfigure exactly the same as the other ones. It still doesn't respond to pings or http admin when plugged into the main network. If I plug into the router directly with a cable, and don't have it plugged into the main network it responds fine.
So then I swap that router with another identical one on the other side of the building. I immediately get the same problem with the swapped router in the Cursed Room. It won't respond to pings or http admin. The router that was in the cursed room works perfectly fine in its new home.
So I figure it might be a bad connection. I tried this with the printers port as well. I plug either a phone(VoiP) or a laptop into either of those wall ports in the Cursed Room and both work perfectly and respond to pings ok.
The switches that all the ports end at are Cisco 3550 and switching the patch cables over to other ports makes no difference. Disabling PoE makes no difference either and it never caused a problem before.
Anyone got any ideas?
