Router works great for about 2-4 days. I can't get WOL passed for some reason, but I'm not that worried about it. DNS relay seems to work. QOS is off. NTP is on, but pointed to the windows NTP server. SecureSpot is off.
About 2-4 days in, the wireless definitely stops being reliable. I was streaming from netflix and was dropping packets just to the router, inside the network. All I had to do to fix it was perform a soft reboot from "Tools -> Device".
I think I'm having the exact same problem when wired, but I'm still working to confirm. My Intel NIC is fine for a few days. Then, out of the blue, it starts dropping the link for a few seconds.
The other thing is the length of dropped packets /outtage will increase the longer it goes without a reset. That is, it will start just dropping a few packets, but if you leave it, eventually it won't respond at all -- not even logging into the management page.
Same as every post I've started: I can repro on demand, so if anyone at DLink is interested in collecting data somehow, just let me know.
In case it matters, both machines are Win7 x64 w/ IPv6 and homegroup. I also have an Xbox 360 that I use daily and a wireless Epson printer that is on 24/7 but rarely used.
