Lenovo Legion Slim 5 16APH8 Ping Spike Issue: The Realtek 8852 CEcard Culprit and How to Deal with It

Question:

How can I prevent ping spikes caused by Realtek 8852 CEcard in Lenovo Legion Slim 5 16APH8?

I have a Lenovo Legion Slim 5 16APH8 laptop and I use it to play online games such as war thunder or genshin impact. However, I often experience ping spikes that last for 2-3 seconds and disrupt my gameplay. I have traced the problem to the Realtek 8852 CEcard, which is the wireless network adapter in my laptop. It seems that this card periodically scans for new connections, even when I am already connected to a network. This scanning activity increases the ping significantly and causes the lag. I have tried updating the BIOS, drivers, and software, as well as resetting the laptop, but none of these solutions worked. The problem has been there since I bought the laptop. Is there a way to permanently disable the scanning feature of the Realtek 8852 CEcard, or to reduce its frequency or impact on the ping? Thank you for your help.

Answer:

If you are a gamer who owns a Lenovo Legion Slim 5 16APH8 laptop, you may have encountered a frustrating issue: ping spikes that ruin your online gaming experience. Ping spikes are sudden increases in the latency or delay between your computer and the game server, which can cause lag, stuttering, or freezing in the game. Ping spikes can be caused by various factors, such as network congestion, interference, or hardware problems. In this article, we will focus on one specific cause of ping spikes: the Realtek 8852 CEcard, which is the wireless network adapter in your laptop.

The Realtek 8852 CEcard is a Wi-Fi 6 card that supports the latest wireless standards and offers fast and stable connections. However, some users have reported that this card also causes ping spikes when playing online games, such as war thunder or genshin impact. The reason for this is that the card periodically scans for new connections, even when you are already connected to a network. This scanning activity consumes bandwidth and increases the ping significantly, resulting in lag spikes that last for 2-3 seconds. This can be very annoying and detrimental to your gaming performance and enjoyment.

Fortunately, there are some possible solutions that can help you fix or reduce the ping spikes caused by the Realtek 8852 CEcard. Here are some steps that you can try:

  • Update the BIOS, drivers, and software of your laptop. This is the first and most basic step that you should do whenever you encounter any issues with your laptop. Updating the BIOS, drivers, and software can fix bugs, improve compatibility, and enhance performance. To update the BIOS, drivers, and software of your Lenovo Legion Slim 5 16APH8 laptop, you can visit the official Lenovo support website and download the latest versions for your model. Follow the instructions carefully and make sure to backup your data before updating.
  • Disable the scanning feature of the Realtek 8852 CEcard. This is the most direct and effective way to prevent the ping spikes caused by the card. By disabling the scanning feature, you can stop the card from looking for new connections and save bandwidth and ping. To disable the scanning feature of the Realtek 8852 CEcard, you can follow these steps:
  • Open the Device Manager by pressing the Windows key + X and selecting Device Manager from the menu.
  • Expand the Network adapters category and right-click on the Realtek 8852 CEcard.
  • Select Properties from the context menu and go to the Advanced tab.
  • Find the Scan When Associated option and set it to Disabled.
  • Click OK to save the changes and restart your laptop.
  • Reduce the power saving mode of the Realtek 8852 CEcard. Another possible cause of the ping spikes is that the card enters a power saving mode when it is not in use, which can affect its performance and stability. To reduce the power saving mode of the Realtek 8852 CEcard, you can follow these steps:
  • Open the Device Manager by pressing the Windows key + X and selecting Device Manager from the menu.
  • Expand the Network adapters category and right-click on the Realtek 8852 CEcard.
  • Select Properties from the context menu and go to the Power Management tab.
  • Uncheck the Allow the computer to turn off this device to save power option.
  • Click OK to save the changes and restart your laptop.
  • Use a wired connection instead of a wireless connection. This is the last resort that you can try if none of the above solutions work for you. Using a wired connection instead of a wireless connection can eliminate the interference and instability that may occur with the wireless network adapter. To use a wired connection, you will need an Ethernet cable and a USB-C to Ethernet adapter. Plug one end of the Ethernet cable into your router and the other end into the adapter. Then, plug the adapter into the USB-C port of your laptop. You may need to disable the wireless network adapter in the Device Manager or the Network and Sharing Center to avoid conflicts.
