I know from experience though, that compatability issues can sometimes be a real pain and give wierd symptoms. Incidently, I am not saying this is the issue here obviously, I do think there may be buffering issues with the 1000s, but you may find the following of interest.
For example if I use the N router Talktalk provide, it works okay on most of my portable devices, but tends to stutter on our ipads a little or my iPhone. (it doesn't seem to like Apple equipment..lol) Plus I discovered a major issue where... if I enabled bluetooth on any of my devices the net speed dropped to zero, this was a real pain as I like to use my BlueTooth headphones when say watching a film etc on my iPad, I also use something called Teamspeak on my ipad for online gaming chat, which of course uses my BlueTooth headphones.
I thought the problem may be my cheapo bluetooth headphones, so I purchased a more expensive branded name pair, which to my dismay made no difference..

strangely when I tried Sony's single ear bluetooth headset with my PS3 that worked without any problems..very wierd says I.
This really frustrated me for 2/3 weeks trying various things with no solution. One day I decided to try a different brand router as I had a couple of older ones in the attic.
I found the old linksys router worked fine, no problems with bluetooth enabled at all, so it was obviously an issue with the talktalk Dlink router and Bluetooth, I assume its something to do with both using the 2.4GHz band, but that applies to other routers too.

Incidently.. before you say it...lol YES I did try every channel on the router, a few times actually.
Anyway... it was definately a compatability issue with the router, I've since purchased a cheapo TP-Link N300 router and speeds are good, not disconnected once and I can at last use my Bluetooth stuff... worked great ever since.
I apologise for going wee bit off topic, but I mention this because one should not rule anything out. I cannot for the life of me see why that original talktalk N router stopped streaming immediately I enabled bluetooth... strange or what!..lol
