iPhone Network Repair

Throughout the years of development of the iPhone, it has seen some improvements in terms of networking.  In the, iPhone 7, iPhone 6s,  iPhone 6 and iPhone 5s, for example, the WiFi chip can make use of the 5 GHz option for the 802.11n connection, while the iPhone 4s can only use the 2.4 GHz option.  These different frequencies do not generally translate into a speed difference, but instead present different options; using 5 GHz reduces the chance of device interference, while 2.4 GHz is known to extend further and pass through objects or walls easier.

Another improvement that came with the iPhone 5 and onwards is the use of 4G networks, also known as LTE.  The previous model could only operate on 3G.  Sometimes 3G connections can be slow, and the validity of 4G speeds is largely contested – however 4G is literally the next generation of wireless technology and will ultimately replace 3G for high-end phones.  4G LTE is considered to be the standard, though many other forms of 4G exist.

All models from the iPhone 4s and onward use Bluetooth 4.0, which is especially desirable for a few reasons.  Firstly, it is completely backwards compatible with older Bluetooth devices; second, it uses far less energy, making devices like wireless headsets far more usable.

With iPhone 6 and iPhone 6 Plus, apple include NFC (Near Field Communication) which allow for Apple’s new mobile wallet service Apple Pay. iPhone 6s user simply tap at participating merchants payment terminal to electronically make in store transaction.

 Connectivity issues

It is no secret by now that there is a signal issue with the iPhone design (the iPhone 4, at least).  The device’s casing acts as the antenna for reception of phone service and WiFi signals – quite an interesting innovation, except for one small problem.  Holding the phone “wrong” can actually reduce or block the reception.

First of all, blocking more of the case than was intended will result in fewer bars or even dropped calls in mid-to-low service areas.  Additionally, the problem largely occurs when the bottom-left portion of the case (screen facing up) is blocked.  For anyone who is left handed or has a tendency to switch hands while talking on the phone, this is a significant problem.

This is just one of the many issues that could be preventing service and WiFi from working on an iPhone.  Other issues range in severity, though most can be fixed with some effort.

Disabled WiFi, Bluetooth, or Network 3G/4G

WiFi can malfunction for a number of reasons.  If you experience an iPhone WiFi gray out, iiPhone and iPad won’t connect to wifi”, the cause is most likely due to the inherent faultiness of the device’s connectivity.

iOS 6 is the root of this issue.  When using the iPhone 5 no service can denote a similar problem, but specifically with the 4s, the device automatically disables hardware components in special instances.  This can either be because they have been idle for too long, they are overheating, or a number of other possibilities.

Symptoms that your phone has automatically disabled components include:

  • iPhone WiFi greyed out – when attempting to turn on the WiFi, the slider is grey and simply stuck in the off position.
  • Missing address field – in the About section of the phone’s general settings, the Wi-Fi Address field is either completely missing any text or says “N/A”.
  • Bluetooth unavailable – when attempting to enable Bluetooth for your phone, there is a loading wheel instead of the on/off switch.

This can affect your network connection as well, rendering 3G and 4G useless. Again, while this is primarily an iPhone 4s WiFi problem, it can happen to other models as well.

Other possible problems

While this flaw by Apple is the cause of the problem a majority of the time, something similar could be affecting your phone’s connectivity.  A few possible instances are:

  • Impact damage to the antenna – if you recently dropped your phone, had it crushed by something, or it otherwise sustained some kind of impact, the antenna could be loose, disconnected, or damaged.
  • Faulty repair – if another portion of your device was recently repaired (by you or a technician) a slight mistake could affect the antenna’s performance.
  • No service – in the case of 3G and 4G, your service provider could be experiencing issues (or you forgot to pay your bill!)
  • Water damage – especially after sustaining a crack to the screen, water can easily get into your device short-circuit or otherwise disturb the WiFi or Bluetooth components.

Fixing the issue

Your can try to a few simple solutions, check if helps:

  • Turn Wi-Fi off and back on
  • Forget to a network auto sign-in, reconnect again.
  • Try reset network setting
  • iOS update.
  • On/ Off your router

If all these failed, likely to be hardware issue. If the problem persists , the best option available is to bring your phone to the professional mobile repair centre .
