WiFi
lWi-Fi is the name of a popular wireless networking technology
lthat uses radio waves to provide wireless high-speed Internet
land network connections. A common misconception is that the
lterm Wi-Fi is short for "wireless fidelity," however this is not the
lcase. Wi-Fi is simply a trademarked term meaning
lIEEE 802.11x.

The iPhone 4s
The iPhone 4s uses a Broadcom BCM4329 WiFi and Bluetooth
controller
the same chip likely used in the iPhone 4. The BCM4329 is a
popular choice for mobile applications
where it may be in use in hundreds of millions of popular mobile
devices — processor analysis firm Chipworks estimates that the
chip was found in more than 50 million devices in the fourth
quarter of 2010 alone.

iOS7
liOS 7 gets a complete design overhaul and adds useful
features like automatic updates to make everyday use
easier. Long-overdue Control Center gives quick access
to most-used features. AirDrop and iTunes Radio are
excellent additions.
lWhile there are a few notable new features in iOS 7, the
new interface is by far the most deeply felt and most
profoundly changed of the batch.

Disadvantage of iOS7
lBesides the massively overhauled design and Control
lCenter,there are few ground-breaking new features
l.
l
The flat design concept favors space over information so
you'll generally need to do more scrolling to get the info
you need.
Some new features aren't available for iPhone4 and 4S
users.

Issue in iPhone 4s with iOS7
A number of iPhone 4S owners their Wifi problems to mentioning that
they encountered the grayed out Wi-Fi button or “unable to connect”
message many times after they upgraded the iPhone 4S to iOS7.
If this occurs, the Wifi option in the iPhone 4S is unavailable, so when
4S owners tap the Settings > Wi-Fi, trying to turn on the Wi-Fi, the
iPhone 4S fails to respond. According to some reports, the annoying Wi-
Fi problem for the iPhone 4S may be caused by the iOS 7.

solution
iOS 7 needs a powerful processor—the "brains" of the device
responsible for carrying out what the software commands.
Apple designed the operating system for its most powerful chip
to date, the 64-bit A7, which includes both a CPU and an
upgraded graphic processor. The OS simply won't work on chips
that predate the A4, the earlier and weaker chip powering the
iPhone 4.

Cont..
It also doesn't help that the iPhones 4 and 4S—the earliest
devices eligible for this software update—have half the onboard
memory, or RAM, of the newest iPhones.
RAM holds recent data for easy access, so the more you have,
the more data you can access quickly, and the faster the
experience feels. The iPhone 5S and 5C boast 1GB RAM. The 4
and 4S each have a mere 512MB.
