ASUS laptop not connecting to internet

Hi sorry for the ChatGPT post but I’ve been on with it for a couple of hours and not getting any joy. I asked it to summarise the problem for a reddit post. Can anyone help please??? Thanks

My ASUS TUF Gaming laptop suddenly lost all internet connectivity today. Both Wi-Fi and Ethernet stopped working simultaneously. Wi-Fi initially disappeared completely from the available network options. I’ve spent hours troubleshooting and haven’t managed to fix it. **Symptoms:** Wi-Fi and Ethernet both stopped working at the same time. Wi-Fi adapter (MediaTek Wi-Fi 6 MT7921) appears in Device Manager and says it’s working properly. Ethernet adapter (Realtek PCIe GbE) is also detected. Windows networking troubleshooter says networking services may not be running. WLAN AutoConfig won’t start (Error 1068: dependency service failed). Windows Connection Manager (Wcmsvc) also fails with Error 1068. Windows Defender Firewall won’t open (Error 0x6D9). Base Filtering Engine (BFE) won’t start, showing Error 5 (Access Denied). ping 1.1.1.1 returns “General failure”. ping 127.0.0.1 works perfectly (0% packet loss). **Troubleshooting attempted:** Network reset and multiple restarts – no improvement. Checked network adapters in Device Manager – both detected. Investigated Windows service dependencies. RPC and NSI are running, but several networking services won’t start. Ran sfc /scannow – found corrupted system files but couldn’t repair some of them. Ran DISM /Online /Cleanup-Image /RestoreHealth – failed with Error 0x800f0915 (repair content couldn’t be found). Tried uninstalling the latest Windows quality update through Recovery – Windows couldn’t uninstall it. Tried Safe Mode – networking issues persisted. Tried Startup Repair – failed with “Your device ran into a problem and couldn’t be repaired”, referencing SrtTrail.txt. Interestingly, Windows Recovery offered to connect to my Wi-Fi network, suggesting the hardware itself might be fine. **My suspicion:** Something has corrupted Windows networking services, possibly related to BFE or a recent Windows update. I really want to avoid a full Windows reinstall, especially one that removes my installed programs and games. Has anyone encountered this combination of errors before? Is there a way to repair BFE or the Windows networking components without resetting Windows? Any suggestions would be hugely appreciated.
