The WiFi connection on your Samsung Galaxy Book4 Pro 16 drops repeatedly – video calls are interrupted, file transfers fail partway through, or the WiFi icon shows disconnected then reconnects every few minutes. Intel AX211 power management is the primary cause of this pattern on the Samsung Galaxy Book4 Pro 16.
This guide covers Intel AX211 driver updates, power management settings, and router configuration to stop WiFi drops on the Samsung Galaxy Book4 Pro 16 in Windows 11.
“WiFi on Galaxy Book4 Pro 16 dropped every few minutes during video calls. It always reconnected in 30 seconds but the call interrupted. Disabled Intel AX211 power saving in Device Manager. No drops since.” – Nabilah, remote educator from Putrajaya
Why WiFi Drops on Samsung Galaxy Book4 Pro 16
The Intel AX211 WiFi adapter in the Samsung Galaxy Book4 Pro 16 uses power management to reduce battery drain. When the adapter detects a period of reduced WiFi activity (such as during video call silence gaps or file transfer completion), Windows can power down the radio briefly. If a beacon packet from the router is missed during this power-down window, the router marks the session as inactive and the client must re-associate, causing the visible drop and reconnection cycle.
- Intel AX211 WiFi adapter power management disconnecting radio during brief activity gaps
- Windows Power plan reducing WiFi adapter activity in Battery Saver or Balanced mode
- Router DHCP lease renewing during WiFi adapter sleep causing brief session interruption
- Intel AX211 driver version with aggressive sleep timer causing drops every few minutes
Fix 1 – Disable Intel AX211 Power Management
Open Device Manager. Expand Network Adapters. Right-click Intel Wi-Fi 6E AX211. Select Properties – Power Management tab. Uncheck Allow the computer to turn off this device to save power. Click OK. Also go to Power Options – Change plan settings – Change advanced power settings – Wireless Adapter Settings – Power Saving Mode and set to Maximum Performance. These two settings prevent Windows from entering the radio sleep state that causes brief disconnections.
Fix 2 – Update Intel AX211 Driver via Samsung Update
Open Samsung Update on the Galaxy Book4 Pro 16 and check All Updates for Intel Wi-Fi or Wireless LAN driver. Install and restart. Samsung-qualified Intel AX211 driver versions include improved power state management that reduces the frequency of radio sleep cycles while still providing reasonable battery savings. Updated drivers also fix specific WiFi drop patterns reported on the Galaxy Book4 Pro 16 model.
Check Router Beacon Interval
Log into the router admin panel and check the 5GHz beacon interval setting. A default beacon interval of 100ms means the router sends a beacon 10 times per second. If the Intel AX211 misses several beacons due to radio sleep, the client deauthenticates. Reducing the beacon interval to 50ms in the router settings increases the frequency of beacons, making it harder for the AX211 to miss enough beacons to deauthenticate.
Fix 3 – Set Roaming Aggressiveness to Lowest
In Device Manager – Intel Wi-Fi 6E AX211 – Properties – Advanced, find Roaming Aggressiveness and set to Lowest. High roaming aggressiveness causes the adapter to search for stronger APs at slight signal fluctuations, momentarily disconnecting from the current AP. Lowest setting locks the adapter to the current AP until signal strength is very poor, preventing roaming-triggered drops in single-AP home environments.
Fix 4 – Disable Samsung DeX Network Mode
If Samsung DeX or Samsung Link are installed on the Galaxy Book4 Pro 16, they can create virtual network adapters that periodically request WiFi adapter state changes. This can interrupt the Intel AX211 WiFi session. Disable Samsung DeX network features or uninstall Samsung network sharing apps to see if they are contributing to the WiFi drops on the Galaxy Book4 Pro 16.
Frequently Asked Questions
Why does WiFi keep dropping on Samsung Galaxy Book4 Pro 16?
Intel AX211 power management disconnects the radio during brief activity gaps. Disable power saving in Device Manager and Power Options to prevent drops.
How do I fix WiFi disconnecting on Samsung Galaxy Book4 Pro 16?
Disable AX211 power management in Device Manager, update driver via Samsung Update, set Wireless Adapter to Maximum Performance in Power Options, and Roaming Aggressiveness to Lowest.
Does Samsung Galaxy Book4 Pro 16 support WiFi 6E?
Yes – Intel AX211 supports 6GHz WiFi 6E. Requires WiFi 6E router for 6GHz access and speeds up to 2.4Gbps.
What WiFi adapter does Samsung Galaxy Book4 Pro 16 have?
Intel Wi-Fi 6E AX211 with Bluetooth 5.3. Supports 6GHz, 5GHz, and 2.4GHz.
Conclusion
Samsung Galaxy Book4 Pro 16 WiFi dropping in Windows 11 is resolved by disabling Intel AX211 adapter power management in Device Manager and Power Options. Updating the Intel AX211 driver via Samsung Update reduces the frequency of radio sleep cycles that cause drops. Setting Roaming Aggressiveness to Lowest prevents roaming-triggered disconnections in single-router environments, maintaining stable WiFi sessions for video calls and file transfers.
