Unstable Bluetooth Connections on Windows

Article ID Code: GK-BT-02

This article covers unstable or intermittent Bluetooth connections on Windows. If your Bluetooth function is completely unavailable, please refer to GK-BT-03: Bluetooth function unavailable instead.

Symptom	Likely Cause
Bluetooth audio stuttering or cutting out, especially with MT7922 network card	2.4 GHz wireless interference or driver/coexistence issue
Bluetooth mouse or keyboard lagging or disconnecting within 1 to 2 meters	Weak Bluetooth signal, antenna issue, or power management setting
Headphones connect but audio quality is poor, mono, or distorted	Interference, driver problem, or unstable Bluetooth profile connection
Bluetooth devices randomly disconnect every few weeks	Driver instability or power-saving behavior
All Bluetooth peripherals lose connection at the same time	System-level Bluetooth service interruption or adapter instability
Placing a hand between the PC and device causes disconnection	Signal blockage, weak antenna connection, or poor antenna placement

Step 1: Switch Wi-Fi to 5 GHz

Bluetooth and Wi-Fi share the 2.4 GHz band on MT7922 and Intel combo cards, which can cause interference and degrade Bluetooth stability. Switching your PC to a 5 GHz Wi-Fi network removes this conflict.

Go to Settings → Network & internet → Wi-Fi.
Connect to the 5 GHz version of your network (usually labeled with "5G" or "5GHz").
If your router only supports 2.4 GHz, consider upgrading the router or using a wired Ethernet connection for the PC to free up the 2.4 GHz band for Bluetooth.

Step 2: Disable power management on the Bluetooth adapter

Windows may automatically turn off the Bluetooth adapter to save power, causing random disconnections.

Right-click Start → open Device Manager.
Expand Bluetooth → right-click your Bluetooth adapter → select Properties.
Open the Power Management tab.
Uncheck "Allow the computer to turn off this device to save power".
Click OK and restart your PC.

Step 3: Update Bluetooth driver

An outdated or incompatible driver is a common cause of Bluetooth instability. For detailed driver reinstallation steps, refer to GK-BT-01 Step 3: Update or Reinstall Drivers.

Important: Always use the official driver from the GEEKOM support website. Do not use the "Search automatically" option in Device Manager.

Step 4: Check antenna connection

Note: Opening the device chassis may affect your warranty. If your device is within the warranty period, contact GEEKOM Customer Service before proceeding.

A loose U.FL/IPEX antenna connector can severely weaken the Bluetooth signal, causing short-range disconnections and signal blockage. For detailed antenna reseating instructions, refer to GK-BT-01 Step 4: Antenna reseating guide.

Step 5 (Advanced): Bluetooth/Wi-Fi coexistence setting

Some Bluetooth adapter drivers include a coexistence or interference mitigation setting that helps Bluetooth and Wi-Fi operate more smoothly together. This option is not available on all adapters or driver versions.

Open Device Manager → expand Bluetooth → right-click your adapter → Properties.
Open the Advanced tab.
Look for settings such as Bluetooth Collaboration, Wi-Fi/BT Coexistence, or Interference Mitigation.
If available, enable the setting and click OK.

Final Recommendation

If Bluetooth instability continues after completing all steps above, the Bluetooth hardware module may be failing. Contact GEEKOM Customer Service and provide your product model, serial number, and a description of the issue.
