IPad 2 wi fi antenna repair. Causes of Wi-Fi breakdowns on iPad. High-quality and profitable service

The antenna is restored, you can assemble the device and check.

There should be no problems with screwing the antenna into place and laying the cable, I will not talk about it in detail.

The most interesting thing is to connect the antenna connector, which is directed downward, to the body.

To connect the antenna, you need to remove the board where it is connected. First, let's remove the metal case of the microcircuits above this board.

Now let's carefully lift and pull out the board we need.

We will pass the antenna wiring with the connector to its native place and connect it to the removed board.

We put the board in place, put on a metal case ... In general, we assemble the device in reverse order.

We include. If you do not want to turn on, then hold down the round button with a square and while holding it, press the power button. Naturally, if the battery is charged.

We are trying to find wireless networks.

For comparison, on the right, a working device is also looking for Wi-Fi networks. iPad 2 with a repaired antenna did not see only one network, and maybe it disdains to display a network with WPA protection. Just at least WPA 2! And besides that, it connects and works. It seems even no worse than with a new antenna. Checked at the far end of the apartment relative to the source of the Wi-Fi signal.

An interesting design feature of the iPad 2 is that the part responsible for the operation of Wi-Fi and Bluetooth - in fact, the Wi-Fi / Bluetooth module itself - is taken out of the main board and mounted on a separate part, which can be very easily removed using a plastic scapula and a small force applied to it. This is a small board with the BCM43291HKUBC chip installed (in the 3rd generation iPad, this is the BCM4330 chip soldered on the main board). In fact, it is the heart of the Wi-Fi / Bluetooth module and is responsible for managing all the logic, thanks to which your iPad can independently connect to familiar networks, display a list of available hot spots to connect to and remember paired Bluetooth devices.

Another, no less important than the Wi-Fi / Bluetooth module itself, is the antenna. It consists of a coaxial cable and a work surface. The antenna is connected to the Wi-Fi module using a cable. The work surface attaches to the right side of the Home button to the iPad case. Three bolts secure the antenna working surface to it, and one secures the coaxial cable. In addition, the working surface of the antenna is glued to the inside of the touchscreen. Very often, when replacing broken glass, inexperienced or careless craftsmen tear off the working surface of the antenna along with pieces of broken glass.

So, we figured out the design features of the Wi-Fi path and now we can begin to explain the reasons that can lead to a deterioration in signal reception, or to the failure of the Wi-Fi module. The most common cause is damage to the antenna working surface. The cause of such a breakdown may be the fall of the iPad, due to which, as a result of deformation of the lower right corner, the touchscreen may come off. When the digitizer starts to peel off from the case, it will pull along with it the part of the antenna that is glued to its bottom. This is enough for the antenna working plane to start tearing in the mounting area with two Phillips 1.7 mm long screws. This damage is enough to significantly degrade the quality of reception. By the way, this problem is absent in the iPad of the third and fourth generations, because there the working surface of the antenna is not glued to the underside of the touchscreen.

In addition, as a result of a strong impact, even without visible external damage, the coaxial cable can break in the area of the ear, with which it is fixed and attached to the polyphonic speaker. A characteristic symptom of such damage is the complete absence of a list of Wi-Fi networks in the corresponding menu item in the iPad settings.

The most deplorable for the iPad 3, in terms of the consequences, is the failure of the BCM43291HKUBC chip located on the Wi-Fi module board. Due to a strong blow, it can crack, or some part of the legs can break off, breaking contact with the board. This can be caused, for example, by a fall from a great height. One of the reasons for this fragility of the microcircuit is the substrate, which is ceramic instead of the usual silicon one. This makes it possible to achieve excellent signal reception quality, however, it reduces the strength characteristics of the microcircuit.

It's the same story with the 3rd generation iPad. The BCM4330 is as fragile as the BCM43291HKUBC in the iPad 2. For the same reasons. The only difference is that it is wired to the main board.

All of the above problems can be repaired. In the first two cases, this is an antenna replacement. This part cannot be restored. In the latter case, there may be several options. The malfunction can be eliminated by warming up the Wi-Fi chip of the module so that it "sits" in place again. But this option works in a very small number of cases. The safest way is to replace the entire Wi-Fi module board. However, this is quite problematic, primarily due to the fact that they are not available as a separate part and can only be removed from the donor.

Tablet iPad 2 connects to wireless Internet Wi-Fi networks with help Wi-Fi module ... The failure of this module makes it impossible to work with wireless Internet networks using a tablet.

Signs that the Wi-Fi module on your iPad 2 is broken include:

for a long time, the Internet speed remains low, while other devices work in this network at normal speed;
the tablet does not load web pages in the browser, online applications do not work.

Reasons why the Wi-Fi module on iPad 2 could break:

ingress of moisture, dirt or dust into the device case;
mechanical damage to the Wi-Fi module caused by a strong shock or fall;
