you may see my reply here and see whether is it similar to your issue...

try place your phone beside the wifi router and get the phone wifi signal at full 3 bar... i guess it will download smoothly

it is the firmware !

ios 6 above for smooth download etc need strong 2/3 bars. even now homesharing, remote etc works only at this.

before 1 bar can but inconsistent.

but i notice when it bumping around 1bar to 2bar... there is where your connection will be mess up.. and you need to on and off the wifi toggle on yr phone to get it back to work...

but a while more, it will down again...

i'm using the stock DIR-615 router given by the unifi btw... partly i think cause by the router but my other idevices are working >< iphone 5 before update also work, but after uodate then dead...

Download from appstore or other sources?

As i mentioned, is not wifi connection related. My wifi signal is full bar is strong. The only different is ios 6, hang...but ios 5...perfect download.

Conclusion...firmware problem, agree guys???

run maxis speedtest.
post a 3 bar, 2 bar and 1 bar.

Server prob.. Not ios.. Mine just ok on all 6.1.2 device.. Streamyx 1mbps..

WIFI full bar does not mean that you will sure get what you expect. It is also depend on the downloading server capacity.. IF you can download others file with no problem, then that is pretty sure is not a firmware issue. Come on man.. over milions is using 6.1.2 include me.. Don't have this issue..

Did you open your eyes big enough to understand what i mean??? Since i'm happy today, let me repeat. In IOS 5 i have no issue at all, only all my devices under 6.1.2 got this issue. Tell me if is not IOS firmware, then is what???

You are just one of million and your substance is mediocre sufficient. So no way on whatever you claimed here....

Ure wrong. Read more on i5 spec. They could have made it more stringent. So he might have a point. On router settings etc and isp. Especially DNS set it at ure isp dns. Not google etc.

for ya info.

As the best setting for i5 is

Wifi

802.11n 20mhz Width (Enable Shortguard Interval) on 2.4ghz 1-11 only ( so wont work on 12,13 and ppl who use 40mhz width/auto on 11. The prob is most routers use shortguard interval option only with width either at auto or 40mhz. So no choice to enable it. Difference aint much just 8Mbps difference. aka 64 vs 72Mbps. So do it at ure diescretion Also at 40mhz u will get full 270 and with SI u get 300Mbps. 20 is 130 with si at 150.

802.11n 40mhz Width (Disable Shortguard Interval) on 5ghz at Channel 40.

this is what i am configured at and its working perfectly hand to hand with all my idevices at home which the full list is
ipad, ipad 2, ipad 4, iphone 4, iphone 4s, iphone 5

From what i saw on the FCC spec on the wifi power transmit. The higher channels transmit more on the router side but requires less on the ideviece. But from anandtech 36 was the best dbm. So set at 40 with Width 40mhz which is supported at 5ghz.

3gs wont work cause i change to 11n only on 2.4ghz. 3gs gets the update via itunes.

So far my idevices are set optimum only after i got homesharing 100% working. So hence if u can get this working perfectly then ure almost there.

btw y 5ghz. Cause finally iphone 5, ipad 4 can wifi sync quite fast at 150Mbps.

before this wifi sync at 64Mbps is unbearable.

**edit.. lol u quoted before i could edit and finish my thoughts...

no problem to get that
i got 10 hours at nearly 1.5days standby with 20-25 percent left.

it all depends on how u optimize the phone and the apps.

will redo it and post.

I have the Same problem like you bro
Bro, u use wifi all the time only right? I can never achieve that in my iPhone @@

around 2-3 hours talk, wifi 2 hours, 2hours gaming, 2-3 hours video. (Some onboard some homesharing via wifi) 3g normally 40mins - 1hour a day .. on Waze. to and fro from work

i find doing the 8 hours trickle charge seriously helps. Hence i've been obediently charging from 11am to 7am everyday. wont remove it from socket at all.

3G on all the way
