Internet stopping after a Windows 11 update is one of the more alarming problems because the symptom — no internet — prevents you from easily downloading fixes. Almost always a driver issue: Windows Update installed a new network driver (Wi-Fi or Ethernet) that doesn’t get along with your specific hardware. The good news: it’s usually reversible. We go deeper on the whole subject in our Complete Guide to Fixing Windows, Browser, and Software Errors.
While connected to the internet through another device (phone, another computer), use these steps. If you have absolutely no internet access anywhere, the USB tethering option below gets you online temporarily to download what you need.
Roll back the network driver — fastest recovery
Device Manager (Win+X → Device Manager) → expand “Network adapters” → right-click your Wi-Fi or Ethernet adapter → Properties → Driver tab → “Roll Back Driver.” If this button is available: click it → select a reason → restart. The previous driver is restored and internet should return.
If “Roll Back Driver” is greyed out (Windows didn’t save the previous driver): you’ll need to manually install an older driver. Get the right driver from the manufacturer’s site on another device → transfer via USB drive → install offline. Intel Wi-Fi: intel.com downloads. Realtek Ethernet: your laptop or motherboard manufacturer’s support page (not Realtek’s generic package). After installing the manufacturer’s driver: the network should restore.
Network stack reset — for when the driver is fine but the stack is broken
Sometimes the update doesn’t corrupt the driver itself but resets Windows networking configuration: IP stack, Winsock, DNS settings. The adapter shows as connected in the taskbar but internet doesn’t work. This is the “connected but no internet” scenario.
Open Command Prompt as Administrator and run these in sequence:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /flushdns
ipconfig /renewRestart Windows after running all five. This resets the networking stack to clean defaults and forces a fresh IP lease. Resolves many “connected but no internet” situations after updates without touching drivers.
DNS changed by the update
Some Windows updates reset DNS settings to automatic (DHCP-assigned). If you had a manually configured DNS (1.1.1.1, 8.8.8.8, or a corporate DNS) that got wiped: your DNS may now point to a non-functional server.
Settings → Network & internet → your connection → DNS server assignment → verify “Automatic (DHCP)” and see if that resolves things. Alternatively, set it manually to 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google) and test. If pages start loading: DNS was the issue.
Uninstall the update as a last resort
If the driver rollback doesn’t work and nothing restores internet: uninstall the Windows Update itself.
Settings → Windows Update → Update history → Uninstall updates → find the most recent cumulative update (labelled with today’s or yesterday’s date) → Uninstall → restart. This rolls back the entire update. Internet usually restores immediately. The update will try to reinstall itself; pause updates (Settings → Windows Update → Pause) for 1-2 weeks while Microsoft hopefully fixes the driver issue in the next update.
To block only the specific driver update from reinstalling: Microsoft has a “Show or hide updates” tool (search “wushowhide” or download from Microsoft’s site) that lets you block specific driver updates from being pushed again via Windows Update.
Our guide on Wi-Fi not working covers the software-side connectivity issues after a driver is in place, and our network adapter recovery covers the more severe cases where the adapter itself disappears. For Windows Update history and understanding which updates affect which components, Microsoft’s Windows Update documentation covers the KB article system where you can look up exactly what each update contains.
Getting online when completely offline
Phone USB tethering is the fastest way to get temporary internet access on a Windows machine with no network adapter working. Connect Android phone via USB → Settings → Hotspot & tethering → USB tethering. iPhone: Lightning/USB-C tethering works similarly. Windows installs a “Remote NDIS” driver automatically (usually within 60 seconds of plugging in) and provides internet through the phone.
Use this tethered connection to: download the manufacturer’s network driver, run Windows Update to get newer potentially-fixed drivers, or download tools needed for further diagnosis. Once the main network adapter is fixed, disconnect tethering.
USB tethering is also useful as a diagnostic: if internet works perfectly via USB tethering but not via Wi-Fi or Ethernet: confirms the phone’s internet is fine, and the problem is specifically the laptop’s network adapter or its Windows driver — not ISP or router issues.
Firewall and network profile changes
Windows updates sometimes reset the network profile from “Private” to “Public.” Public profile applies more restrictive firewall rules that can block specific types of traffic — not internet broadly, but certain applications or services may stop working.
Settings → Network & internet → your connected network → Properties → Network profile type → confirm it matches your actual network (Private for home/office, Public for untrusted hotspots). If it was reset to Public for your home network: change to Private. This relaxes the firewall to appropriate home/office rules.
VPN and virtual adapter conflicts from updates
Windows updates sometimes conflict with installed VPN software, corrupting virtual network adapters. If you have a VPN client installed (Cisco AnyConnect, GlobalProtect, NordVPN) and internet stopped after an update:
- Device Manager → Network adapters → look for VPN-related virtual adapters with yellow warning triangles
- Uninstall all VPN virtual adapters
- Run Winsock reset commands above
- Restart Windows
- Reinstall the VPN client fresh
This is especially common with Cisco AnyConnect and Juniper/Pulse Secure — their virtual adapters can conflict with updated Windows network stack components. Fresh reinstall after the update usually resolves the conflict.
IPv4 vs IPv6 configuration issues
Some Windows updates change default protocol handling. If your router or ISP doesn’t properly support IPv6 but Windows now prioritises IPv6 over IPv4: internet appears to work (the connection exists) but pages load slowly or fail because IPv6 DNS lookups are timing out.
Test: Command Prompt → ping google.com. Does it show an IPv6 address (2001:…) or IPv4 (1.1.1.1 style numbers)? If IPv6 and you’re seeing connection problems: Settings → Network → your connection → Properties → uncheck “Internet Protocol Version 6 (TCP/IPv6)” → OK. This forces Windows to use IPv4 only. If internet works after this: your network infrastructure doesn’t support IPv6 properly. Re-enable it when your router firmware is updated to support it correctly.
Proxy and LAN settings changed by update
Less common but real: Windows updates occasionally change proxy settings. Settings → Network & internet → Proxy → confirm “Automatically detect settings” is On and “Use a proxy server” is Off (unless you deliberately use a proxy). If “Use a proxy server” shows as On with an address you didn’t enter: the update changed this. Toggle it off.
Internet Explorer / Edge legacy proxy settings (sometimes still referenced by older applications) can also be affected. Control Panel → Internet Options → Connections tab → LAN settings → confirm “Automatically detect settings” is checked and no proxy address is configured unless you use one intentionally.
| Symptom after update | Most likely cause | Recovery path |
| No network adapter, no internet | Driver corrupted or removed by update | Device Manager → roll back driver, or reinstall manufacturer driver |
| Connected icon, no actual internet | Network stack reset or DNS changed | Winsock reset commands; manually set DNS |
| Some sites work, others don’t | IPv4/IPv6 priority shift | Disable IPv6 temporarily; test |
| VPN software broke after update | Virtual adapter conflict | Remove VPN adapters; reinstall VPN client |
| Network works but firewall blocking apps | Profile reset to Public | Change network profile to Private |
| Nothing works, can’t get online to fix | Complete network failure | USB tether from phone; download driver; install |
The driver rollback is the cleanest fix when available — it directly reverses the change that caused the problem. When Roll Back is greyed out: the Winsock reset combined with a fresh manufacturer driver download covers most cases. The update uninstall is the fallback when everything else fails, buying time until Microsoft releases a patched driver in the next update cycle.
Checking what the update actually changed
Understanding what specific update broke the internet helps both fixing it and preventing recurrence. Settings → Windows Update → Update history → look at the date of the last update. Note the KB number (e.g., KB5034765). Search that KB number on Microsoft’s website to see the release notes — they list known issues including network adapter problems.
Microsoft’s Windows Health Dashboard (support.microsoft.com/en-us/windows/windows-11-health-dashboard) lists known issues for current Windows 11 versions. If a specific KB update broke Wi-Fi for a broad category of users: it’s listed there, often with a workaround or confirmation that a fix is coming. Knowing you’re in documented-known-issue territory reduces the troubleshooting pressure — wait for the next update to fix it, use the workaround listed, and uninstall the problematic update in the meantime.
Driver update prevention for the future
Windows Update automatically installs driver updates alongside OS patches. For users who’ve had driver-caused problems: you can reduce the risk going forward. Settings → System → About → Advanced system settings → Hardware tab → “Device Installation Settings” → “Yes” or “No (your device might not work as expected).” Setting to No prevents Windows from automatically installing manufacturer drivers via Windows Update — you control driver updates manually from manufacturer sites.
Trade-off: you need to manually check for driver updates occasionally. For network adapters especially, the manufacturers release meaningful stability improvements that you’d be missing. Monthly check of your adapter manufacturer’s driver download page takes 5 minutes and keeps drivers current without risking Windows Update pushing something untested.
When network issues persist longer term
If internet is intermittently broken (works sometimes, fails randomly) rather than completely absent after the update: the driver may be partially functional but unstable. Symptoms: connection drops randomly, pages fail intermittently, speed fluctuates dramatically.
Extended-stability fix: uninstall the Windows-provided driver → install the manufacturer’s current driver from their site → this driver went through the manufacturer’s own QA process for your specific hardware rather than Microsoft’s generic testing. The manufacturer driver is almost always more stable for specific hardware combinations than Windows Update’s generic version.
If even the manufacturer driver is unstable: roll back to an older version. Most manufacturer driver download pages have an “older versions” or “release history” section. Going back one or two versions often hits a known-stable point for your hardware generation while you wait for a fixed current driver.
Safe Mode with Networking — diagnostic baseline
If you’re unsure whether the issue is Windows itself or a third-party program conflict: boot into Safe Mode with Networking. Hold Shift → Restart → Troubleshoot → Advanced options → Startup settings → Restart → press 5. In Safe Mode, only essential Windows components load. If internet works in Safe Mode but not normally: a non-Windows program is causing the conflict. The culprit is usually a VPN client, firewall software, or network monitoring tool installed before the update.
This diagnostic also confirms whether the network adapter and its driver are fundamentally functional. If internet doesn’t work even in Safe Mode with Networking: the driver itself is broken (or missing), confirming that driver installation is the right path forward.
Restoring a system restore point
If the problem started immediately after an update and nothing else has changed: System Restore is an option. Search “Create a restore point” → System Properties → System Restore → Next → find a restore point dated before the problematic update → Restore. This reverses Windows to its state before the update, including drivers and registry settings.
System Restore doesn’t affect personal files (documents, photos, downloads). It does affect installed programs and Windows settings. After restoring, Windows Update will offer the same update again — pause updates immediately after the restore to prevent it reinstalling automatically.
One caveat: not all Windows 11 installations have System Restore enabled by default. Check: search “Create a restore point” → if the Status column shows “Disabled” for the C: drive: System Restore was never enabled and no restore points exist. Enable it now for future protection, but it can’t help retroactively. For the current issue, use the driver rollback or update uninstall approach instead.
The hierarchy of interventions for internet lost after update: driver rollback (quickest, most targeted) → Winsock reset (addresses stack corruption without touching drivers) → update uninstall (rolls back everything, most disruptive) → System Restore (similar to update uninstall but via a different path). Try them in that order — the first one that works ends the process without unnecessary disruption.
A note for anyone dealing with this across an IT fleet: when a Windows Update breaks network connectivity for multiple machines simultaneously, the fastest enterprise mitigation is using WSUS (Windows Server Update Services) or Intune to block the problematic KB update from deploying to additional machines while remediating the affected ones. Rolling out Winsock reset commands via Group Policy script and the driver download via software deployment are more scalable than individual machine fixes when the issue affects dozens of workstations. You might also run into No Internet After a Windows 11 Update.
