Banner I would love to hear more updates from you on this. I am still trying to figure out how those 2 settings you recommended improved things. You must have a lot more patience than me for the trial and error testing
If changing those settings improved things I wouldn't worry too much about the why. D-Link will figure it out.
I've had DNS relay "Off" and StreamBoost Updates "On" and the My Network, Priorities, and Statistics pages are all still functioning and I have not needed to reboot the router. It seems like the culprit is indeed the DNS relay.
However, the only outstanding problem I still have on v1.11B03 is once I re-enabled SB Updates I started having problems with Skype calls again. From time to time I can't hear my cousin (who is in the other room connected to the same router) over Skype and we have to restart the call. The call never drops and he can still hear me but I can't hear him anymore. It's really odd.
It may just be coincidence I'm not entirely sure that the Skype issue is related to SB Updates. The only thing that I noticed was anytime this appeared in the logs;
Jan 19 00:00:01
USER root pid 428 cmd cull_incoming_pcaps
Jan 19 00:00:01
USER root pid 403 cmd cull_incoming_pcaps
a few minutes later Skype would act up and after restarting the call it would be good again until the next "cmd cull_incoming_pcaps". It could just be coincidence.
For now it's probably best to leave both DNS Relay and SB Updates disabled. I'm done testing this firmware for the time being.
