I have found a random problem with my ReadyNas Duo since we had a power cut this week.
The setup is as follows
Fibre Modem - cat6-Wireless Router - cat6 - 5 port gigabit netgear unmanaged switch - cat5e - readynas duo - cat5e - desktop pc
The desktop PC can see the network and the outside world and devices on the LAN, the readynas duo isn't visible on the lan, sporadic ping requests and raidar cannot see the device.
If I plug both the nas and the PC into the router on Ethernet ports on the back all is ok. However when the two devices are in the Gig switch I cant see the nas. I can see PCs which are in different parts of the house from the PC when plugged into the gig switch but I cant see the nas.
Ive powered all hardware down and brought it back up, no difference. I have not changed any firmwares on anything since the well before the powercut, none of the cables have been changed. All hardware is plugged into a surge protector (and I know all is ok as connectivity works if I plus into the router rather then the gig switch.)
Can anyone shed any light on why when both are on the gig switch I cannot see the nas?
The net is that if you plug the NAS into the router it works, and if you plug it into the switch it doesn't. Based on that, it seems plausible that something is broken in the switch. (Not a complete failure of course, since the PC still works).
Does "can't see the nas" mean that ping fails? When plugged into the switch is the ethernet led green?
Yes, when the Nas is in the gig switch the LED is green on the switch, and theres activity on the NIC of the NAS but pings fail, im concluding that theres something amiss with the switch, but as you say not a complete failure, as its a simple unmanaged gig switch ill be hitting amazon for a new one today and see if all is resolved. I shall post back in a day or three after delivery.
New switch arrived in the post today, all wired in and connectivity is restored.
Thanks for the suggestion, now lets see if I can wangle a return on the old netgear switch, it might be old, but its not exceeded the MTBF rating..... I sense my changes a low!
