This really shouldn't come as a surprise.

Great marketing, including stifling dissent. Rarely first to market, mainly
first to mass market. Average products.

Subject: [AusNOG] Apple iPhone5 Wifi connectivity problems - faulty Apple
wireless chipsets?

Hi everyone happy new year.

I've tried to post this twice to the Apple Support Forums but they seem to
not like it.

I was wondering if anyone on AUSNOG is having the same iPhone5 Wifi issues
and if so, please contact me off-list.

Could be nothing, could be something.  The fact Apple keep blocking my posts
is a bit bizarre too.  Maybe they didn't like the tag shame-on-apple? :)

BACKGROUND:

iPhone 5 with IOS6 and had nothing

but Wifi problems.  Home network not working (despite being upgraded to
latest firmware).  Intermittent access while overseas in US hotel (all my
other devices were fine) and access to my mifi was generally Ok.

Back home and upgraded IOS 6.02 keen to get this disaster sorted.  Still
doesn't work.  Reset my network settings, still doesn't work.  turned off
LTE, still doesn't work.

POSSIBLE SOLUTION:

After

a ridiculous amount of grief, I had all put totally given up.  I read a
post  about the fact that the person could connect on his work 5Ghz network
and decided to go to the config of my wifi access point to see if I could
"turn off" the 2.4Ghz option and just leave the 5Ghz option.

Not an option.  I use a Fritzbox (really happy with).

But

while I was playing around in the wireless options, I noticed that my 2.4Ghz
frequency transceiver was set to the recommended channel setting of
"autoselect".  Autoselect seemed to be selecting channel "1" on the 2.4Ghz
was in use by three other wifi's around here.  The wireless settings page
(which is really good on the Fritzbox) showed that channels 1-7 were in use
by other access points, but 8-14 were clear.  I  over-rode the automatic
channel selection and selected Channel "10", hit "save this setting" and
then BAM! MY IPHONE CONNECTED TO WIFI FOR THE FIRST TIME AT HOME!!!

Now I appreciate at this

stage it doesn't make much sense and it maybe illogical, but it would appear
that on my iPhone (at this stage and it's only been an hour) that either
going "manual" instead of automatic channel select or selecting a "clear"
channel on my access point has resulted in my iPhone  locking onto Wifi (or
both).

Maybe iPhone 5 has a

problem with access points that do certain "handshakes" on automatic channel
selection (which doesn't quite make sense because its already made the
channel selection) or maybe it has a problem in the "channel 1"

band of 2.4Ghz (which could mean a faulty piece of hardware in the wireless
chip - which could be why Apple have kept quiet), or maybe it doesn't like
"sharing" channels or maybe the wind just changed direction  and it decided
to work.  But I had to share this in case this actually works with anyone
else.

Be keen to see if this works for

anyone else and I have my fingers crossed that it keeps working and this
wasn't some fluke and it falls back.

FURTHER RESEARCH:

I've

done some research on this  and it appears that everyone who is having
problems with Wifi connectivity on the iPhone5 appear to have an Apple WIFI
chipset.  Not all Apple Chipsets are having problems but all the problems
seem to be with the Apple Chipsets (only brief research conducted).

Intel Wifi/Wireless Chipsets seem to be fine.

My Wifi

Chipset MAC address on my iPhone started with 34:C0:59 (which is listed as
Apple).  Can I ask that you enter your MAC address (by going into

Settings>General>About and scroll down to Wifi Address) into this

website and see which chipset you are using (Apple or Intel).

Keen

to know if it's the Apple Wireless Chipset.  Please post the following if
you are having problems and whether this solution worked:

[example]

Problem:  iPhone5 can see wifi access point but can't connect MAC Address
(only need first 3 hex codes) 34:C0:59 Chipset Manufacturer (enter into site
above):  Apple

I'd be keen to also see if the people having bluetooth problems are also
using Apple Wireless Chipsets too.

Thank you!
