Windows 11更新后出現Wi-Fi問題，可依次嘗試以下解決方法：1. 檢查并確保Wi-Fi在設置中已啟用，同時確認飛行模式未開啟；2. 重啟路由器和調制解調器，先拔插設備等待30秒后再依次重新連接；3. 更新或回滾網絡驅動程序，可通過設備管理器操作或手動下載最新驅動；4. 運行系統(tǒng)內置的網絡故障排查工具以檢測并修復常見問題；5. 若上述方法無效，可嘗試重置網絡設置，但會清除所有已保存的Wi-Fi和藍牙設備。多數情況下，這些步驟能有效解決更新后的Wi-Fi連接問題。

After a Windows 11 update, Wi-Fi issues can pop up for several reasons—driver conflicts, system bugs, or even settings that got reset during the update. It’s frustrating when everything worked fine before the update, and suddenly you’re stuck with no internet.

Let’s break down what usually causes this and how to fix it.

1. Check if the Wi-Fi is Enabled in Settings

Sometimes after an update, your Wi-Fi might just be turned off by default.

• Go to Settings > Network & Internet > Wi-Fi
• Make sure the toggle at the top says Wi-Fi On

If it's off, switch it on and see if your network appears. This sounds basic, but it's surprising how often this is the issue.

Also, check Airplane Mode — it might have been toggled on accidentally during the update process.

2. Restart Your Router and Modem

This is one of those classic fixes that still works more often than people expect.

Here’s what to do:

• Unplug both your modem and router
• Wait about 30 seconds
• Plug them back in, starting with the modem first
• Wait until all the lights stabilize before turning on the router

Give your PC a minute to reconnect once everything is powered back on. Sometimes the connection just needs a quick reset after a major OS change.

3. Update or Roll Back Your Network Driver

Windows updates can sometimes mess with drivers, especially if there's a newer version that doesn’t play well with your hardware.

To check your driver status:

• Press Win X and select Device Manager
• Expand Network adapters
• Right-click your Wi-Fi adapter (should include words like "Wireless" or your brand like Intel, Realtek, etc.)
• Choose either:
  • Update driver
  • Roll back driver (if you know it was working before the update)

If you're not sure which option to pick, try rolling back first — it’s usually safer if the problem started right after an update.

You can also go to your laptop/desktop manufacturer’s website and manually download the latest Wi-Fi driver for Windows 11.

4. Run the Network Troubleshooter

Windows has a built-in tool that can detect and sometimes automatically fix common network problems.

To run it:

• Go to Settings > System > Troubleshoot
• Click Other troubleshooters
• Find Internet Connections, then click Run

It won’t always find the problem, but it’s worth trying because it can catch simple issues like IP conflicts or DNS errors.

5. Reset Network Settings (If All Else Fails)

If none of the above work, resetting your network might help. It’s like a clean slate for your internet setup.

Here’s how:

• Go to Settings > Network & Internet > Advanced network reset
• Under “Network reset,” click Reset now
• Confirm that you want to reset everything

?? This will remove all saved Wi-Fi networks and Bluetooth devices, so only do this if other fixes don’t work.

If you’ve gone through these steps and still can’t get online, the issue might be with your hardware or ISP, not the update itself. But for most users, one of the above methods gets things running again.

基本上就這些。
