The Realtek Rtl8821ce Is Experiencing Problems

Our teachers are having major problems with using Teams for meetings. They’re having a lot of problems with it and it is very ‘glitchy’. Video and voice are lost very frequently, or even very sporadically. Ultimately, we narrowed down the problem to these laptop models and Wi-Fi adapters, in particular. In fact, I swapped out the adapter for a Qualcomm Atheros QCA61x4A and the performance has drastically improved, leading to the disappearance of the problems.

In many cases, updating the Realtek driver and installing the most recent version of the driver corrected the Realtek PCIe GBE family controller issue. 

There may be times when you don’t have a network under Windows 10 or your Realtek PCIe GBE family controller keeps disconnecting. A yellow exclamation mark will appear in Device Manager after the network adapter tree extension. When Device Manager reports an error code 31 or 12, that is the network adapter.

In this error, there are two possibilities. Either the drivers are conflicting with the motherboard or you have a dead integrated LAN card on your motherboard.

You should immediately resolve the problem with the Realtek network driver for Windows 10 if you have any problems with the Realtek PCIe GBE controller family.

Repair the Realtek Family controller

Repair the Realtek Family controller

A system restore point is used

Follow these steps to get back to your system restore point when everything is working fine. If you have a system restore point, you may be able to save a lot of trouble.

  1. You will need to hold down the Windows key and type rstrui.exe while holding down the R key.
  2. You should now be able to restore your computer to the state it was before the error occurred by clicking Next, selecting a restore point from the date when everything worked, and then completing the wizard.

Manually installing the driver

The LAN controller driver can be installed manually if you do not have a system restore point, or if you prefer not to use that method. Before you begin, download the LAN adapter drivers that came with the laptop/motherboard.

  1. Press R and then type devmgmt.msc.
  2. Realtek’s PCIe GBE family controller can be found by expanding the list of network adapters.
  3. Make sure the driver software is up-to-date by right-clicking.
  4. Specify the correct driver you previously downloaded in manual mode by selecting your own drivers.
  5. After the installation has been completed, reboot your device.

NOTE: If this doesn’t work, try removing the battery from the motherboard for a minute and then reinstalling it before updating the drivers. This will reset the BIOS and help you if Windows is stuck with an old driver and allow you to install a new driver.

Getting a PCIe Network Adapter

You may have a dead network adapter if none of these methods work for you.
There is only one way to fix this problem: you need a new PCIe network adapter. Fortunately, these days, they are very inexpensive. Once you’ve found a wireless adapter that meets your needs in terms of speed and compatibility, you’re good to go. However, you need advanced skills to replace the adapter, so if your router supports wireless networking, you may want to get a USB wireless adapter instead.

The above methods will help you figure out the cause of your problem and correct it, regardless of whether it is a software issue or hardware issue.

Reinstall the driver that is causing the problem

  1. You can launch Device Manager by pressing Windows + R and typing “devmgmt.msc” (without quotation marks).
  2. The Realtek PCIe GBE Family Controller can be found under “Network Adapters” by right-clicking on the item.
  3. After selecting “Remove,” confirm by selecting “Yes.”.
  4. Restart your device to save the changes. I recommend that you disconnect and re-plug the Ethernet cable to ensure that Windows automatically installs the drivers.
  5. The driver can be disconnected and re-enabled if it cannot be removed.
  6. You can also select Properties by right-clicking the file.
  7. The drivers should now be rebooted.
  8. If the Realtek PCIe GBE Family Controller driver is not working, reboot your computer to save your changes.
