Sporadic timeout in internal network to reach BR200/BR500 (see attached network map)
Dear community, You were very helpful in the past, therefore I try it again. I need some troubleshooting advice on the following after many tries, but the problem persists on my network with 6 ne...
Finally I found the solution. The issue does disappear once I changed from "Auto Detect" to "Auto Config" in the IPv6 Config of the BR200. It seems that "Auto Detect" is creating this lag every 15min a DHCP lease extension is received from the ISP. I think this is a bug, because auto detect should not bring down the router for 5-15 seconds after such a harmless message.
Unfortunately I was unable to file a bug report (purchase date older than 3 month). Can anyone help me how to contact netgear that they are aware of that bug? I'm happy to assist.
Dear community,
I now have captured all traffic going in/out of the BR200 on all three ports and VLANs.
Monitoring Setup:
- Port Mirroring of Port 1-3 (Master Switch) to Port 5 (capture)
- ICMP pings from 192.168.20.32 (wireless client)
As you can see, at time 13:03:39.272945, the router on 192.168.20.250 becomes unreachable (visible in the screenshot) and resumes operation 5-15 seconds later.
From long-term tests I can can confirm that his happens exactly every 15min.
I can't see any suspicious activity before on any of the VLAN's, floods or any race condition in ARP requests or similar.
Thanks for any hints!
