Hi, I switched from an Apple router to the RT-AC66U. Everything works fine but when any of the Apples in my household is waken up from 'sleep'. Regardless of 2.4 or 5 Ghz it takes up to one minute to connect to the internet. The wireless LAN symbol is active, but whenever someone tries to connect to a website, she gets a Code: Error 105 (net::ERR_NAME_NOT_RESOLVED): Unable to resolve the server's DNS address. Even entering Comcast's DNS directly into the client Mac does not help. 'Enhanced interference management' is set to disabled (as recommended in some posts here) The RT-AC66U shows the correct SWFL Comcast DNS. The RT-AC66U is running on Merlin 126.96.36.199.266.23 (had the same issues with latest original firmware). The Apples are on latest 10.8.2. I tried various settings with no luck so far. I could really need some help.
