Lenovo ThinkPad T14 Gen 4 AMD WiFi Dropping Windows 11

Your ThinkPad T14 Gen 4 AMD randomly drops WiFi every few minutes, reconnects on its own, or loses connection entirely during video calls. This is a well-documented issue tied to the AMD RZ616 WiFi 6E adapter power management settings in Windows 11.

The solution involves disabling aggressive power saving on the WiFi adapter and optionally updating the driver from Lenovo Support. This guide walks you through both approaches.

“My ThinkPad T14 disconnects from WiFi every 10-15 minutes during Teams calls. Found out the adapter was going to sleep to save power even while I was actively using it.” – Azizul, network administrator from Petaling Jaya

Why WiFi Drops on ThinkPad T14 Gen 4 in Windows 11

The AMD RZ616 (Radeon RZ616) WiFi 6E adapter shipped in many ThinkPad T14 Gen 4 AMD units has a known issue where Windows 11 power management puts the adapter to sleep too aggressively. This causes short disconnections that look like a network problem but are actually a driver or power policy issue.

• AMD RZ616 WiFi adapter enters sleep mode during low-traffic periods
• Windows 11 power plan set to Balanced – reduces adapter performance
• Driver version below 5.0.0.x has known disconnection bugs
• Roaming aggressiveness set too high causes unnecessary AP switches

Fix 1 – Disable WiFi Power Management

Open Device Manager (Win + X), expand Network Adapters, right-click your AMD RZ616 or Intel AX211 adapter, select Properties, go to Power Management tab, and uncheck Allow the computer to turn off this device to save power. Click OK. Also go to the Advanced tab and set Power Saving Mode to Maximum Performance.

Fix 2 – Update Driver from Lenovo Support

Visit support.lenovo.com, enter your ThinkPad T14 Gen 4 model number, and download the latest AMD WiFi driver for Windows 11. Versions 5.0.0.517 or later have stability improvements. Install and restart.

Registry Fix for Roaming Aggressiveness

In Registry Editor, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}. Find the subkey for your WiFi adapter (look for DriverDesc matching RZ616 or AX211). Add or modify RoamingAggressiveness (DWORD) and set it to 1 for least aggressive roaming. This stops unnecessary AP switches that appear as disconnects.

Fix 3 – Set High Performance Power Plan

Press Win + R, type powercfg.cpl, and in Power Options select High Performance or Lenovo Balance. Balanced mode throttles the WiFi adapter. If High Performance is not listed, open Command Prompt as administrator and run: powercfg -duplicatescheme 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c to restore it.

Fix 4 – Use Lenovo Vantage Power Settings

Open Lenovo Vantage, go to Device – Power, and set the mode to Better Performance or Maximum Performance. This prevents Windows 11 from putting the WiFi adapter to sleep during active use sessions.
