Wi-Fi Works Slow or Disconnects on a Laptop: Common WLAN Adapter Problems

In both new and older laptops, one of the most common issues is the gradual failure of the Wi-Fi + Bluetooth wireless module. This problem is especially frequent in Lenovo laptops manufactured from 2020 onward. Wi-Fi cards also fail very often in modern gaming laptops, as many manufacturers have massively switched to low-cost wireless modules based on MediaTek and Realtek chipsets.

Despite marketing claims of high performance, Wi-Fi adapters fail more frequently every year. In addition, Intel AX200 and AX201 wireless cards are known to fail after several years of use. In our service center, we routinely replace these adapters with more reliable, corporate-grade wireless modules designed for long-term stability.

Typical Laptop WLAN Adapter Malfunctions

The most common symptoms of a failing Wi-Fi / Bluetooth module include:

  1. Windows cannot connect to certain Wi-Fi networks, while the same laptop may work normally with another router.
  2. Very low internet speed — websites load slowly and downloads are limited. A Speedtest check often shows speeds dropping to 2–10 Mbps, even when the laptop is close to the router.
  3. Weak Wi-Fi signal strength — only networks in the same room are visible, while neighboring networks no longer appear.
  4. Wi-Fi internet disconnects during online gaming or video calls via messengers or Zoom.
  5. Short Bluetooth range — wireless headphones or speakers lose connection at a very small distance from the laptop.
  6. Windows cannot detect available Bluetooth devices, even when they are in pairing mode.
  7. Audio dropouts and Bluetooth disconnects when using wireless sound devices.
