I haven't done enough testing to be sure but I think there is definitely something amiss with wifi in the new 5.
I've got 6 iOS devices...
iPhone 5 and 3GS running ios6 and ios5.1
iPad 3 x2 ios6 and iOS 5
iPod touch 1st gen iOS 3.1.3
ATV3 (latest update iOS 5.1 equiv I think)
I use a uPNP media server and plug player and I get major buffering issues with relatively low bitrate audio when plugged into my stereo upstairs... I've used the 3GS, iPod touch and iPad here without stuttering issues. It seems that the 5 is dropping connection or packets causing the stuttering issue. Loading web pages it seems fine but any streaming on wifi is a no go compared to older devices.
I have yet to try out the two iPads next to the 5 at with different iOS versions to compare but from day 1 my wife's iPad, though the exact same iPad 16gb wifi only model, consistently could not get the same range as mine, especially testing out back on our patio. I'd get 2 bars wifi she would get 1 or no connection in the same location. Going to 2.4GHz helped but I found it odd to be such a variance between the same model. However both iPads did not get the same wifi range as my 3GS or old iPod touch...
