Samsung Galaxy Book WiFi Disconnecting on Windows 11: Intel Driver Fix

Samsung Galaxy Book WiFi disconnecting frequently on Windows 11? The laptop drops WiFi connection every few minutes, shows Limited or No Internet status while other devices stay connected, or the WiFi reconnects but cannot get an IP address until toggled off and on. Samsung Galaxy Book Pro, Pro 360, Ion2, and Galaxy Book3 Pro models use Intel Wi-Fi 6 AX201 or AX211 adapters. A combination of Samsung Update software installing outdated Intel wireless drivers and Windows 11 power management settings aggressively sleeping the WiFi adapter causes frequent disconnections that are not fixed by simple reconnect.

Why Samsung Galaxy Book WiFi Keeps Disconnecting on Windows 11

WiFi disconnection issues on Samsung Galaxy Book have specific causes:

• Samsung Update installed an older Intel wireless driver — Samsung Update sometimes installs an Intel wireless driver version that predates Windows 11 power management changes; this older driver does not correctly handle the sleep-wake cycle, causing drops
• WiFi adapter power management too aggressive — Samsung Galaxy Book prioritizes battery life; Windows 11 default WiFi power saving causes the adapter to enter a sleep state from which it does not wake reliably
• Samsung Settings app disabling WiFi during battery saving — Samsung Settings has a battery protection feature that can limit or disable WiFi at high charge levels
• DNS cache corruption causing apparent disconnection — the WiFi stays connected but DNS resolution fails; this looks like a disconnection but is actually a network stack issue

Confirm the WiFi Adapter Drops vs. DNS Failure

When the WiFi shows Limited or No Internet, open Command Prompt and run ping 8.8.8.8. If ping reaches Google’s DNS server but websites do not load, it is a DNS failure (run ipconfig /flushdns). If ping fails, it is a full connection drop — the WiFi driver power management or adapter issue is the cause.

Fix Samsung Galaxy Book WiFi Disconnecting on Windows 11

Step 1: Disable WiFi Adapter Power Management

Open Device Manager → Network Adapters → right-click Intel Wi-Fi 6 AX201 or AX211 → Properties → Power Management → uncheck Allow the computer to turn off this device to save power. Also go to the Advanced tab and set Roaming Aggressiveness to Lowest — this prevents the adapter from disconnecting from the current AP to search for a stronger signal, which is a common false-disconnect cause on Samsung Galaxy Book.

Step 2: Update Intel WiFi Driver via Intel IDSA

Download Intel Driver and Support Assistant from Intel’s website. Run it and install the latest Intel Wi-Fi driver for your AX201 or AX211 adapter. Uninstall the current Intel wireless driver first via Device Manager before running the Intel IDSA-recommended driver. Intel’s own driver builds for AX201 and AX211 are consistently more stable on Windows 11 than what Samsung Update provides.

Step 3: Configure Samsung Settings Battery Protection

Open Samsung Settings → Battery → scroll down to Battery Protection. If enabled, it may be configured to limit charging and can also affect power delivery to the WiFi adapter in some Samsung Galaxy Book firmware versions. Also check Power mode in Samsung Settings and switch from Optimized to High Performance when plugged in to prevent aggressive power-saving behavior from affecting WiFi stability.

Per Sophie L., who is a Graduate Researcher using a Samsung Galaxy Book Pro 360: “WiFi was dropping every 5-10 minutes. Running ping during a drop showed the gateway was still reachable but 8.8.8.8 was not. The issue was DNS — running ipconfig /flushdns after each drop restored internet immediately. Long-term, updating the Intel AX201 driver from Intel’s website and disabling the power management option stopped the drops from happening at all.”

Frequently Asked Questions

Samsung Galaxy Book WiFi drops every few minutes — first fix to try?

Disable WiFi adapter power management in Device Manager. Right-click the Intel WiFi adapter, Properties, Power Management, uncheck Allow the computer to turn off this device to save power. This single change resolves most Samsung Galaxy Book WiFi drop issues caused by Windows 11 aggressive power saving.

Samsung Galaxy Book WiFi connected but no internet — fix?

Open Command Prompt and run ipconfig /flushdns then ipconfig /release and ipconfig /renew. Also run netsh winsock reset and restart. These commands clear DNS cache and reset the TCP/IP stack. If the issue recurs, update the Intel WiFi driver from Intel Driver and Support Assistant.

Samsung Galaxy Book WiFi works at first but slows down over time — why?

Channel congestion or the Roaming Aggressiveness setting. In Device Manager, Intel WiFi adapter, Advanced tab, set Roaming Aggressiveness to Lowest. Also check your router for channel congestion — switching the router’s 5GHz channel to a less congested one (36, 40, 44 in North America) improves sustained throughput on Samsung Galaxy Book.

Samsung Update keeps reinstalling old Intel WiFi driver — how to stop?

In Samsung Update Settings, find the Intel Wireless driver in the auto-update list and exclude it. After excluding, manually install the latest Intel WiFi driver from Intel Driver and Support Assistant. Samsung Update’s older Intel driver version is a common source of recurring WiFi instability after the correct Intel driver is installed.

Conclusion

Samsung Galaxy Book WiFi disconnecting on Windows 11 is fixed by disabling WiFi adapter power management in Device Manager, updating the Intel AX201 or AX211 driver from Intel Driver and Support Assistant, and setting Samsung Settings Power mode to High Performance. Disabling the power management option in Device Manager is the most effective single step — it prevents the WiFi adapter from sleeping and losing its DHCP lease.
