Final 6.2.1 update causing LAN instability/sluggishness
After upgrading to 6.2.1 on an RN314, the network adapters no longer appear in the UI. In general it looks like the network parameters were reset. I can only recover the device by letting my router ...
I want to add what I have discovered myself, in case it is helpful here.
I started having issues this morning after I updated our ReadyNAS 314, but I didn't connect the issues I have having with the update until much later. First our internet went out, which I thought was our ISP, but I was able to connect with a single system bypassing our router. I plugged the router back in and ran a packet capture an noticed our entire upload bandwidth was saturated with OpenVPN packets to our offsite salesman. I disabled our OpenVPN server and the internet came back to life.
Around the same time I was notified of a printer issue. One of our wireless printers wouldn't talk to the network, and I couldn't log in to the WAP that it should connect to. So I mirrored this port to my computer and ran another packet capture. I noticed the network was being flooded with DHCPv6 requests, thousands every second. I don't run an IPv6 network, and don't even have server support for it at this time. Some more digging tracked it to an IPv4 address in my DHCP pool range. Even more digging tracked it back to my ReadyNAS MAC, which also had a static IPv4 address. I am only using one network port on this, so I don't know why it would have 2 IP addresses, or what it is trying to do with IPv6. I had to unplug it to bring my network back, but now I don't have my ReadyNAS, my main storage archive.
The only app I have installed is Anti-Virus Plus. I don't run any media servers. If I can provide any more info, let me know and I will. I hope to get this tracked down soon.
