it must be specific to only some network cards model, and not be present on the Centrino 6230.
First, thank you for your response. I appreciate it.
Admittedly, I know little about this stuff. However, when I do nothing to my PC, and do the re-apply (on the router), the problem fixes itself. If I reboot/disconnect using my PC, then it does nothing to fix the problem.
Which leads me to believe the problem is with the router--but again, I'm a neophyte. Unless this is a case of the client behaving badly, causing some sort of corruption/disruption on the router--in which case i would argue that the router should be more robust than that.
And out of curiosity I looked on my device manager to see what i have: Intel Centrino Advanced-N 6250 AGN. I wonder if there are settings on this driver I can monkey with--may try that.
This appears to be in the same ballpark with yours--this is running on Windows 7 on a two year old Samsung laptop. Just as information.
**EDIT***
I did a "check for driver update" on that in Windows . . and BOOM . .there was a new one. Have no idea what I was running before and didn't think to look. Now it's dated 12/06/2012 version 15.4.0.11. Will monitor carefully.Don't know why that driver was out of date or how out-of-date it might have been. I thought Windows Update checked for these things. After spot checking other drivers it seems like most of them are up to date.
I can't imagine problem solving something like this out in the field, with so many variables--hardware, drivers and versions, environment, etc.
Fingers crossed that this give some sort of illumination

Best bet would be to send a PM to CL-Jeremy here on SmallNetBuilders to see if Asus knows anything about a known issue - he works for them. I do know that the reason there's no 372 release for the RT-AC66U yet is they are working on some stability issues with wireless - no idea if it's the same issue reported here or a different one.
Hopefully this is the one. It seems to be the most common complaint on here and the negative reviews on Amazon.
But I may hit him up.
Thanks again, Merlin. Only been around a week or so, but your contributions are obvious. I like this site, and the reviews here are the primary reason I picked the ASUS.
