anyone else own the wzr-d1800h or buffalo wirless n router?

Wondering what other peoples experiences have been with buffalo's new wireless ac router when using wireless n/g, or other buffalo products in general.

I was pretty excited to get this router, but now that I have it, I find it performing far worse than my 7 year old wrt-54gl... range is worse, signal strength is worse at same distances, internet speed seems to be slightly worse (i'm guessing due to signal strength issue)... not sure what gives here.

I originally bought this because the range on my linksys wasn't quite doing it when I moved into a 2 story 3br house vs our old one floor condo. When I'm upstairs my galaxy nexus gets about 0-25% signal (this phone seems to have pretty crappy wifi reception in general), other devices got decent signal, but could be better. The main reason for going with the buffalo router was that I thought I might get their wireless bridge in the future and take advantage of ac for streaming bd-iso. Other than that I though I'd just finally move up to wirelss n, and since I read good things about this router's performance (esp on 5ghz) and it would future-proof me a bit I thought it was a good call. My PS3 used to get 100% and phone close to that when I am downstairs in the livingroom... now the ps3 is showing 90% and phone at 50! (phone is on 5gh and used to be 2.4)...

Everyone says wireless n is supposed to have better range, so I thought I'd see SOME sort of improvement, but since I had already planned to use the linksys (running dd-wrt) in repeater mode upstairs it's not like I was expecting the buffalo to solve all my range problems by itself.

If this is all there is to it and I'm not missing anything though- there's just no way I would pay 180 bucks even to have a router that performs exactly as good, let alone worse.

I experimented with using different channels/auto, throughput levels, 2.4 vs 5ghz... I'm not really seeing anything that is dropping my disappointment level. If anyone has had a good experience with this router outside of sitting directly in front of it, please let me know!

I know it's new, but nobody else has any experience with this router? Or any stories of other buffalo routers?
