Quick Fix

RescuePC Toolkit includes a dedicated Network Repair tool that runs all 7 of these fixes automatically. One click, internet restored in under 2 minutes.

Why This Happens

“Connected but no internet” means your PC successfully connected to your router (WiFi or Ethernet), but the router can't reach the internet — or more commonly, your PC's network stack is corrupted and can't properly route traffic even though the physical connection is fine.

Common causes:

Corrupted DNS cache — stale or poisoned DNS entries
Winsock corruption — the Windows networking API is broken
DHCP failure — your PC didn't get a valid IP address
Proxy settings — malware or VPN left proxy settings enabled
IPv6 conflicts — IPv6 misconfiguration blocking IPv4 traffic
Driver issues — network adapter driver crashed or is outdated

Fix 1: Flush DNS Cache

This fixes the problem about 40% of the time. Stale DNS entries prevent your PC from resolving domain names to IP addresses.

Open Command Prompt as Administrator
Run: ipconfig /flushdns
Run: ipconfig /registerdns

Fix 2: Reset Winsock

Winsock is the Windows networking API. If it gets corrupted (common after malware removal or failed VPN uninstalls), nothing network-related works properly.

Open Command Prompt as Administrator
Run: netsh winsock reset
Run: netsh int ip reset
Restart your PC (required for Winsock reset to take effect)

RescuePC Does This Safely

RescuePC's Network Repair detects whether you're on WiFi before resetting adapters. It skips dangerous operations (like adapter reset) on WiFi connections to prevent disconnecting you mid-repair. The manual commands above don't have this safety check.

Fix 3: Release and Renew IP Address

If DHCP didn't assign a proper IP address, you'll be connected but unable to reach anything.

Open Command Prompt as Administrator
Run: ipconfig /release
Wait 5 seconds
Run: ipconfig /renew
Run: ipconfig and verify you have a valid IP (not 169.254.x.x)

If your IP starts with 169.254, that's an APIPA address — meaning DHCP failed completely. Check your router or try a different Ethernet port.

Fix 4: Change DNS Servers

Your ISP's DNS servers might be down or slow. Switching to Google or Cloudflare DNS often fixes the problem instantly.

Open Settings → Network & Internet → Change adapter options
Right-click your active connection → Properties
Select “Internet Protocol Version 4 (TCP/IPv4)” → Properties
Select “Use the following DNS server addresses”
Preferred: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare)
Alternate: 8.8.4.4 or 1.0.0.1
Click OK, close everything, try again

Fix 5: Disable Proxy Settings

Malware, VPNs, and corporate tools sometimes leave proxy settings enabled. This silently breaks internet access.

Open Settings → Network & Internet → Proxy
Turn off “Use a proxy server”
Turn off “Automatically detect settings” (then turn it back on)

Fix 6: Reset TCP/IP Stack

The nuclear option for network issues. This resets the entire TCP/IP stack to factory defaults.

Open Command Prompt as Administrator
Run: netsh int ip reset resetlog.txt
Run: netsh int ipv6 reset
Restart your PC

Fix 7: Update or Reinstall Network Driver

If none of the above worked, the network adapter driver itself may be corrupted.

Open Device Manager (devmgmt.msc)
Expand “Network adapters”
Right-click your WiFi or Ethernet adapter → Uninstall device
Check “Delete the driver software for this device”
Restart your PC — Windows will reinstall a fresh driver
