i suspect there is a firmware issue... when im on ios6.0.1 or ios6.1 with my iphone 5, wifi is no issue at all... after upgraded to ios6.1.1 and 6.1.2, here the problems come... the new firmware tend to weaken the receiving of wifi signal...

why i said so?

my router is placed at ground floor while my room at 2nd floor (an ordinary double storey house). my deskstop (2nd floor) got full wifi signal most of the times and smtimes drop to 4bar... but my iphone5 got a very weak signal... smtimes can't even connect to whatsapp. it is not a ISP problem as my pc surfing and running normally while the phone hv problem to connect...

the remedy for me is turn off the wifi and turn it on again... smtimes when i wake the phone up from sleep, it can't even hook to the wifi signal...

yesterday, i discovered smthing... when i get my phone stay closely with the router, the appstore and whatsapp connection speed is tremendous fast... i place my phone beside my router for 30min at sleep mode... when i wake it up it hook to the wifi within 2sec...

i move around 10 foot steps to my living room... the living room is separated with the router with a merely wood cabinet, the wifi signal drop to the lowest and the speed become extremely slow... (same situation as i am at the 2nd floor) hey, i am at the same floor with the wifi router (within 100m distance) !

and it didn't happen to my ipad 2, ipod touch 4th gen and iphone 4 all with ios6.1.X (they all behave normally either in 1st or 2nd floor)... only iphone 5 with ios 6.1.X with this issue, apple pls release an update...


**i tried on "RESET ALL NETWORK SETTING", guess what? after phone restart im still able to connect to the wifi without enter WEP code... i assumed it didn't help me to reset anyway

sorry, i was plan to include that statement but forgotten...
i'm not expected the wifi performance of i5 same as my deskstop as the pc one will be much more powerful in terms of receiving the signal...

anyway, anything i can choose beside of the WEP? might give a try...

and what router do u suggest that can work with my unifi and hypptv? prefer to have a brand with specific model... signal must be good as well la...

thanks for yr feedback in adv

it is not the phone problem.. it is the firmware problem...
