The culprit is often a built-in module Realtek RTL8723BE, which is known for its peculiarities in working with Windows drivers and physical wear of contacts. If your laptop is losing network, running at slow speeds, or not seeing access points at all, it may be time to do some in-depth diagnostics.
Disassembling the device to replace or reconnect this component requires care, as manufacturers HP Often they use specific fasteners and fragile plastic latches. In this article we will analyze in detail the process of dismantling the back cover, removing the board and correctly connecting antennas to the module RTL8723BE. You will learn how to avoid damage to cables and what to do if the problem cannot be solved by simple replacement.
Preparation of the workplace and necessary tools
Before you begin physical disassembly HP, it is necessary to provide a safe environment for the operation of electronics. Static electricity can damage your motherboard instantly, so the first step is to use an anti-static wrist strap or periodically touch a grounded metal object. Make sure your work surface is clean, dry, and well-lit so you can see small screws and connectors.
You will need a set of screwdrivers with Phillips bits, preferably magnetic, so as not to lose the fasteners inside the case. You will also need a plastic card or a mediator to carefully pry off the covers without scratching the case. To remove the module Realtek Sometimes tweezers are needed if it is a tight fit. Be sure to prepare a container for the screws so you don't mix up their lengths when assembling.

It is important to unplug your laptop and remove the battery if it is removable. If the battery is built-in, you need to find a way to disconnect it from the motherboard immediately after removing the back cover. This is a critical safety step because connecting live loops can short out a circuit.
The process of removing the back cover and accessing the module
Access to the insides of laptops HP often hidden under a bottom cover that is held in place by screws and plastic latches. Some screws may be hidden under the rubber feet, so you need to carefully lift them up. Inspect the case for screws that are tightened at different angles, as the manufacturer may have used hidden fasteners to secure the hard drive or motherboard.
After unscrewing all visible screws, begin to carefully pry off the cover with a plastic pick. Move around the perimeter, gradually releasing the latches. Do not use excessive force as the plastic may crack, especially at the corners of the case. Once the cover snaps off, set it aside, but do not tear it off completely if the touchpad or other sensor cable is connected to it.
Inside you will see the motherboard, cooling system and various expansion modules. Module RTL8723BE usually located on the top of the laptop, closer to the screen hinges, and is a small circuit board with two antenna wires (black and white). It can be covered with a metal shielding plate or be in the public domain.

If you see a metal casing above the module, you need to carefully unscrew it. Be careful with the screws as they can be very small and easily lost. After removing the cover, you will have direct access to the Mini-PCIe slot into which your Wi-Fi adapter.
Diagnostics and replacement of the Realtek RTL8723BE module
Module RTL8723BE often fails due to overheating or oxidation of contacts. Before replacing, try carefully removing it and putting it back in to make sure there is a good connection. Inspect the gold contacts on the board and on the motherboard - they should not have dark spots, scratches or signs of oxidation. If the contacts are dirty, they can be carefully wiped with alcohol.
The antennas are connected to the module via thin coaxial cables. They are fixed with special metal clamps. To remove them, you need to carefully pry the latch with tweezers and pull it up, and then move the wire to the side. Do not pull on the wire itself, as the inner core may break. When installing new cables, make sure they click into place.
To replace the module you will need a new adapter. Realtek RTL8723BE is outdated and only supports the 802.11n standard, which may not be sufficient for modern Internet speeds. Consider installing a more modern module, e.g. Intel Wireless-AC, if your laptop allows it for compatibility and connector reasons.
When removing the old module, pay attention to its fastening. It is usually held on by one screw on the side. After unscrewing the screw, the module will rise at an angle and can be easily removed from the slot. Place it in an antistatic bag for disposal or sale for parts.

☑️ Instructions for safe replacement
Installing a new module is done in the reverse order. Insert it into the connector at a 30-degree angle, make sure the contacts are aligned, and carefully press it onto the board, securing it with a screw. Connect the antennas: usually the black wire goes to the Main (1) connector, and the white wire to the Aux (2), but the markings may vary depending on the board revision.
Software configuration and elimination of driver conflicts
Physically replacing a module does not guarantee operation if old drivers remain in the system. Before installing a new device, go to Device Manager and delete all entries related to network adapters Realtek. The uninstallation should include the option to uninstall the driver software. This will prevent conflicts that often arise when mixing software versions.
After rebooting the system, Windows may automatically install the basic driver, but for full functionality it is better to download the current version from the official website HP or Realtek. If you installed a new module from Intel, download drivers specifically for this model. An incorrect driver may result in the module being visible on the system but not being able to connect to networks.
Sometimes the problem lies in the energy saving settings. Go to the properties of the network adapter in Device Manager, go to the tab Power management and uncheck the box Allow this device to turn off to save power. This will prevent Wi-Fi from accidentally turning off when the system is idle.
Also check your BIOS/UEFI settings. Make sure that the built-in Wi-Fi module is not disabled at the firmware level. Go to section System Configuration or Advanced and check the device status Wireless. If it is disabled, enable it, save the settings and restart your laptop.
⚠️ Attention! Never use drivers from unverified third-party sites, as they may contain malware or cause system instability. Always download software from the manufacturers' official resources.
What to do if the driver does not install?
If the automatic installation does not work, try downloading the driver from another device, transferring it to a USB flash drive and installing it manually through the device manager by selecting “Update driver” -> “On my computer” and specifying the folder with the files.
After installing the drivers, check the operation of the module. Connect to the network and perform a speed test. If the connection is stable, the problem is solved. If not, perhaps the problem is not in the module, but in the antennas or the router itself.

Replacement with module Intel often solves problems not only with speed, but also with compatibility. Drivers Intel are considered standard and are less likely to cause errors in Windows. However, before purchasing, make sure that the new module physically fits into the Mini-PCIe slot of your laptop and that the BIOS does not have a Whitelist (list of allowed devices) that blocks the installation of third-party modules.
Some models HP really have such a list, and trying to install someone else’s adapter will result in the laptop giving an error when loading and not turning on. In such cases, you will have to either look for a compatible HP module or reflash the BIOS, which is a complex procedure.
⚠️ Attention! Before purchasing a new module, be sure to check compatibility with your laptop model on forums or in the manufacturer's specifications to avoid blocking the device by the system.
If you are replacing the module with a more powerful one, make sure your antennas (wires) are long enough to reach the new connector without tension, otherwise the signal will be lost due to poor contact.
If replacing the module does not help, the problem may be in the antennas themselves. Check the integrity of the wires going to the screen. They often bend around the hinges and break inside the insulation. This leads to the signal not reaching the module or returning with losses.
