Immediate Fix (Method 1)
The most effective way to stop WiFi drops on systems using AMD Radeon Software is to deactivate the AMD Link server functionality. This feature is often enabled by default and can interfere with wireless network stability.
Follow these steps to disable it immediately:
- Right-click your desktop and open AMD Software: Adrenalin Edition.
- Click on the Settings (gear icon) in the top-right corner.
- Navigate to the Devices tab.
- Locate the AMD Link Server toggle and switch it to Disabled.
Once disabled, restart your computer to ensure all background processes associated with the link server have terminated. Most users report an immediate cessation of lag spikes and connection timeouts.
Technical Explanation
AMD Link acts as a local host server, allowing you to stream games and monitor metrics on mobile devices. To maintain this connection, the software frequently pings your network adapter to scan for available devices.
This “background scanning” behavior creates a conflict with many WiFi drivers, particularly those on 2.4GHz and 5GHz bands. The constant polling causes the adapter to momentarily stall, resulting in the “drops” or high latency spikes users experience during gaming.
The table below highlights how AMD Link settings impact your network performance based on common user benchmarks:
| Feature State | WiFi Stability | Latency (Ping) |
|---|---|---|
| AMD Link Enabled | Unstable / Frequent Drops | High Spikes (200ms+) |
| AMD Link Disabled | Stable / Constant | Low / Consistent |
Alternative Methods
Method 2: Stop the AMD Link Service via PowerShell
If the toggle in the Radeon software does not stick, you can manually stop the service using a command-line interface. This ensures the background process is killed entirely.
# Run this command in PowerShell as Administrator to stop the AMD Link service
Stop-Service -Name "AMD Link Controller" -Force
Set-Service -Name "AMD Link Controller" -StartupType DisabledMethod 3: Firewall Block
If you wish to keep the software installed but prevent it from accessing your network, you can create an outbound rule in Windows Firewall. Block the “AMDLink.exe” executable to prevent it from polling your router.
This method is recommended for advanced users who want to keep the Adrenalin software features active while insulating their network adapter from polling requests. Ensure you apply the rule to both Public and Private profiles.
