I was hoping 6.1.4 would help but I guess not,,, why is apple not fixing this issue,,,they are getting more annoying by the day

After installing the latest iOS update (6.1.4) the issue was fixed for me
The in-app downloads in Podcasts app are now flying :-)
Will check from home but seems it is solved - thanks apple

Dear Apple (yes I know that you don't monitor these discussions, but my interaction with Apple support & Genius bars has yeilded no positive results, this is all I have left),
It is time that someone started to take this issue seriously, what is the point at all of a premium phone that can't accomodate the most basic of tasks, downloading a 20MB file in less than 30 minutes over a WIFI connection that is over 100Mbps!
PLEASE PLEASE PLEASE I hope that someone stumbles over this thread who can actually do something about this long standing and verry frustrating issue. If not, and because Podcasts are key to me, I have no choice than to move elsewhere for my next phone for the first time since the iPhone 3G.
Here is some fresh screen shots that show the issue continuing with 6.1.4 (10B350).
Please don't make me have to switch over to a HTC One or wrose!!!!!

Yea,,, this is a really bad wifi bug,, I think it maybe hardware related that's why they haven't fixed it,, unless iOS 7 will fix it,,, no idea,, but its very frustrating,,,I can't watch any live video streams without buffering either

I'm with you ozsmacd... I've been watching this thread for months waiting for a fix... Nothing. I've replaced my phone twice. I've tried all the tweaks and DNS settings with no success. Podcasts download at a decent speed, but video buffering is still terrible. I decided a few weeks ago that this will be the last iPhone I buy for a long time. I think Apple has gotten complacent. Pretty designs only get you so far.

I don't think it will be fixed until iOS 7 or Until the new iPhone comes out,, sadly

Hi it does work for me on both work and home WIFI - iPhone 5 - after latest iOS update
However I did notice that there is sometimes a big difference between podcasts - e.g NPR podcasts tend to download a bit slower than others - in any case much faster now and much nicer UX - I can update episodes before leaving the house in a few minutes -

I think your problem may be different to ours,,, our problem is that the wifi is slow but when you are downloading an AppStore app in the background the wifi flies/ blazes but when it's done downloading the wifi goes back to normal and crawls ,,,

Yeah I also wondered if it was a problem with specific Podcast sources, however if I run the same download on my wifes iPhone 4 or my iPad3 (or iPad2) I don't have the issue, the downloads fly.
As all other people are finding, if I have another download running (either an App store download or using the multiple Podcast download feature in Downcast or iCatcher) my speeds are back to normal and just fine.
This wouldn't be quite such a problem if I could rely upon iTunes wifi syncing to work even 20% of the time, sadly it doesn't (ath.exe 50% cpu utilisation bug), so I'm forced to remember to plug my iPhone into my computer to sync podcasts. Somewhat odd in this wireless and mobile world to be so tethered.
This is also my 3rd iPhone 5, having had mine replaced twice by apple, one for a broken power button and the other due to dust behind camera lense (two things I'm sure they could have fixed in 5 seconds in the shop, but hey).

The whole thing is so frustrating its almost unbelievable at times,, very strange there hasn't been another fix by another user or apple,,,

So a bit more information, decided to so some network sniffing, on the next hop device up from my iPhone. As far as I can make out the issue I'm facing is massive amounts of TCP Retranmissions, resulting in a ever shrinking TCP Window (down to 136 bytes, I think normal window size is 16384).
I've completed this testing with iPhone 5, iPhone 4.0, iPad 2 and iPad 3.....only the iPhone 5 shows this issue (I also tested with both iCatcher and Downcast, with multiple podcast sources).
So something appears broken in the iPhone 5 network stack, something that is causing TCP Retransmissions that are well excess of normal, this results in a decrease in the TCP window size, causing slow downloads.
Anyone else agree with my largely un-informed explination above...........
Here is a screen shot of the network capture, 126.96.36.199 is the podcast source, twit cachefly cache server & 192.168.252.64 is my iPhone 5.
