Nice work ozsmacd, I've done something similar and am working a little down the track.
I've now thrown my WLAN into a bridge arrangement and look at packet size which is now 1510 and I can get a consistent download. Whilst I've had this cronic problem for a while, my current situation is that I cannot replicate the fault !!!
I think you are on to something.
I'm seeing the retransmissions too, looking further into it, they appear to be related to Null Function Packets where the STA (iPhone) is telling the AP it's going to sleep (it's doing this LOTS), this, by design, causes the AP to buffer / queue packets and make them available when the STA reports back that it's online again.

Good find,,, the question is can this be fixed with iOS 7 or is it a hardware issue,,,or can it be fixed with a work around without having to download something in the background to speed up the wifi

Felt for a long time that this is a network stack problem. A concurrent download might just change the timing enough to change things. Also, the problem seems to be worse with higher latency connections (compared to older devices) which again might be a tming issue.
I think it would be good to post the findings to the Apple feedback site.

So for those who want a work around to solve this issue, and I can't believe that I didn't think of this sooner, use a proxy server in your local network. A good example for Windows is WinGate (http://www.wingate.com free now for 3 users, you don't need more), just install the program and accept defaults, then under your WIFI connection define the proxy server.
It's not an actual fix, but it's close enough for me & my lord it's sorted out my issue right away.
Today is a good day, I have 200MB podcasts downloading over WIFI in just over a minute, reliably.

Perhaps we can all take the 5 minutes to provide bug feed-back to Apple about this?

Great idea! Also kind of proves how broken the iPhone 5s (and iPad4's and iPad Mini's) network stack is. Not sure how to accomplish this with Macs though.

How do you set the wingate up? I'm totally lost,, lol

I figured the proxy thing out and it's working great now,,it's a shame that we have to even do it,,something is badly wrong

I can confirm connecting through a proxy server solves the issue. You can install Squid using Homebrew if you are good at unix stuff or try Squidman for OS X. Don't know if Squidman works on 10.8 though.

Geez Apple, get your bugs straightened out.

Installed Squid via Squidman (on a Lion machine). I can also confirm it makes a considerable difference. I can now download large files from Dropbox in a reasonable time. Mind you, it's not as fast as my 3G connection, even though the 3G connection tests slower than wifi using Speedtest.
I also tested speeds on high latency connections (something I've bought up before). I'm in Sydney, and Speedtest to my closest server (with a ping of 22) is around 17mb/sec (with or without the proxy). However, if I change to a Singapore server, which has a ping around 6-700, without the proxy I get speeds down around .3 to .6mb/sec. With the proxy, this jumps to 3 to 3.5mb/sec.
I'm hitting the Apple feedback page again!

The wingate server proxy works well but for some reason around 6 or 7pm Everynite the wifi gets slow again but is fine again in the morning,,, why is that ? Any ideas ,,is it something I have to change in wingate or is it just Internet traffic in the neighborhood slowing it down ? Any ideas? Thanks in advance

I'd do a few speedtest.net bandwith tests from your PC or MacBook, it's likely this is simply congestion on your broadband (are you on cable?).
When you say slow, what example could you provide?

I wonder if iOS 7 will fix this wifi issue,, I will try the iOS 7 beta when it comes out,,,do you guys think iOS 7 will fix it or is it hardware related,, this stack issue
Currently Being ModeratedJun 3, 2013 6:46 PM (in response to berniefl34)
I would think it would be fixable with an update - some sort of driver issue or maybe firmware. Fingers crossed anyway!
