Final 6.2.1 update causing LAN instability/sluggishness

It does not seem to be a wide spread issue with 6.2.1 and command 1.27 (many are running it without issue)

Good to see Netgear involved! Just talked to a friend who has RN312 who upgraded to 6.2.1 final without any issues. That confirms your statement.

I suggest you first look to the differences between the connman packages 1.27-netgear1 and 1.26-netgear1. 1.27 doesn't work for me. 1.26 does. I believe that to be a better approach to come to the deeper underlying issue. Otherwise, we are just shooting in the dark for the root cause. The ball is your corner now.

No, don't have Logitech/UE media Server (using Plex).

I would look in the direction of IP problems. During research the ISP helpdesk made me set the router to factory settings. That cleared all the fixed IPs I had configured and at next reboot the RN got a different IP from DHCP. Seems to me, from that point on the BOND on eth0 and eth1 on RN didn't play well with the newly assigned IP address. The RN kept complaining about "Cannot connect discovery server" on the front display. Not sure what the discovery server is or why RN should contact it. But it might kick off the problem. Read in some other thread that the connman config got messed up, but not sure if that is related.

Common things I would look for first, based on the testing sofar:
- Is there a BOND set between eth0 and eth1 on RN?
- Is the router configured to always assign same IP to RN?
- Is NAT and/or port forwarding applied on the router towards RN?

Don't think that the installed apps are at the hart of the problem, but to rule things out, these are my installed apps.
