Final 6.2.1 update causing LAN instability/sluggishness

Did a OS reinstall of the OS 6.2.1 (final) and this seems to have fixed the issue for me. At least no more hangs in the router and the connection to Internet stays open for my PC and Wifi devices. And most importantly my website is back online. Because of the re-install, the bond that I had set on the two network cards is now gone and I connect through one NIC only now (eth0) again. So for me the root cause was a mismatch of network settings in the RN516 and the router. After the OS reinstall these were set back to default, I think. Espescially the bond between the two NICS I had, seems to throw a curveball. Still the RN516 should never disable a router to provide connections. It should just not have been reachable, if the IP addresses are incorrect.

Will run like this for a while, with only one NIC attached to the router. Will look some more into this after the holidays. Already spend 2 days on this issue, so I'm done for now. Happy holidays!

The OS reinstall for the RN516 is described on pages 55 and 56 of the ReadyNAS OS 6 Desktop Storage Systems Hardware Manual manual (April 2013, 202-11206-03). For other model look in the index and find your model and the "Boot menu". I used the option "OS reinstall". (Be careful not to select the previous item "Factory default", because that will erase all your data. Read the caution notion in the manual!).
