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.
Finally I was able to isolate the problem. The ISP has a lease time of 30min, but extends every 15min. Exactly at this time, the BR200 logs "Internet connected". This is the time where all ports go down for a couple of seconds (destination not reachable). I attached you a snapshop of the BR200 logs.
Configuration or BR200:
- IPv6 for the ISP (Auto Config).
I'll file a bug report since I'm unable to do further investigations, the log function of the BR200 is quite limited (no syslog or debug logs as far as I can see).
