RN102 will not Acquire and IP and Connect to Network
Here is the situation.
I have a ReadyNAS 102 version 6.10.2 connected to a Netgear 16 port Gbit switch which is then connected to my Netgear WNR3500 wireless Router which provided the assigned IP either via Mac Address or DHCP. The NAS will no longer automatically acquire an IP address even though the NAS is set to use DHCP to get the IP assigned from the router.
Originally I had the router configured to assign the IP to each piece of equipment hardwired to the Gbit Switch via the router. The NAS and other hardwire equipment always had the same IP address assigned on my internal network. Only Wireless devices got their IP assign via the DHCP server on the router.
Recently I ran into an issue which caused me to hard reset the router and it deleted all my address reservations which assign IP addresses based on MAC addresses. I did this so I could remotely access certain equipment on my network and port forwarding. The NAS does not run 24/4 only 16 hours a day. Because of the router being hard reset and before the NAS turned on one of the wireless devices acquired the same IP address (192.168.1.10) the NAS has always been using which caused an IP conflict. I figure out which device was using the NAS's IP address and forced it to acquire a new one. However, at this point the NAS still would not connect and I could not figure out why the NAS kept trying to acquire the old IP address even though the router was assigning all new IP addresses via DHCP.
After some trouble shooting I got the NAS to connect, only when the NAS was connected directly to the router bypassing the Gbit Switch all together. For a time being it keep using the original IP it always had, eventually I got it assigned a new IP from the DHCP server on the router. However, If the NAS is not direct connect to the router it will not show up on the network. Using all the same cables as connected to router, and then reconnecting to the switch the network lights on the ENET port only blinks a couple of time and stop and will not connect to the network. When connected to router the network light blink like normal and continue to blink so the network adapter in the NAS is fine.
I know this is long, however, I can not seem to figure out why the NAS is now refusing to connect to the network when the GBit switch in between NAS and the router. Everything else will connect through the switch and I changed cables on the NAS and tried in all the different ports with the same result. For some reason the NAS no longer likes the switch.
Any insight anyone can offer on how to fix this.

The next troubleshooting steps are to
(a) try switching the NAS to a different switch port
(b) try connecting router to the the switch using a different switch port.
(c) try using different ethernet cabling.
Are the other devices on the switch behaving normally? What model switch are you using?

Are the other devices on the switch behaving normally? - Yes all other devices are working fine once I cleared the IP conflict issue since all devices are not using the routers DHCP service to get their IP, no MAC address reseversation.
What model switch are you using? - I will have to look later, however, I am 99% certaint this is not the issue at this point since it works for everything else I plugged into it.
At one point I was thinking the ENET port on the NAS went bad, until I plugged NAS into the router and it used the originally MAC address reservation IP (192.168.1.10) and showed up on the network, it keep reusing this IP address and I knew this would be problematic since the rounter is only using DHCP and the NAS turns on and off each day. I finally the NAS will put a new IP address when it turns on when directly to the router but when the switch is between the router and NAS the it fails to acquire an IP address and self assigns.
Did you also set a static IP in the NAS? If so, it may now be conflicting with another device since it's not reserved.
