🔄 Start here — works for both Windows and Mac

Reboot your router and modem. Unplug both from power. Wait 60 full seconds. Plug the modem back in first, wait 30 seconds, then plug the router back in. Give it another minute before testing. This fixes the majority of drop issues on any device.

⊞ Windows-specific Wi-Fi troubleshooting steps.

Check If It's Your Device or the Network

1

Test on a second device

Connect a phone or tablet to the same Wi-Fi. If that device stays connected, the problem is with your Windows PC's Wi-Fi adapter or settings — not the router. If every device drops, it's a router or ISP issue.

2

Run the built-in diagnostic

Right-click the Wi-Fi icon in the taskbar (bottom right) and select "Troubleshoot problems." Windows will automatically scan for common issues — wrong IP address, DNS problems, adapter errors — and often fix them automatically.

Reset the Network Adapter

3

Forget and reconnect to your Wi-Fi network

Go to Settings → Network & Internet → Wi-Fi → Manage known networks. Click your network name and select Forget. Then reconnect as if it's a new network and enter your Wi-Fi password. This clears any corrupted connection data.

4

Update your Wi-Fi driver

Press Win + X → Device Manager. Expand Network adapters, right-click your Wi-Fi adapter, and choose "Update driver" → "Search automatically." An outdated driver is a common cause of intermittent drops on Windows.

💡 Windows tip: Open Command Prompt as administrator and run these two commands one at a time:
netsh winsock reset
netsh int ip reset
Then restart. This resets your network stack and often fixes persistent Wi-Fi issues.
Mac-specific Wi-Fi troubleshooting steps.

Check If It's Your Mac or the Network

1

Test on a second device

Connect a phone or another device to the same Wi-Fi. If it stays connected, the problem is with your Mac's Wi-Fi settings — not the router. If every device drops, it's a router or ISP issue.

Forget and Rejoin the Network

2

Remove the saved network and reconnect

Go to System Settings → Wi-Fi. Click the (i) icon next to your network name and select Forget This Network. Click the Wi-Fi name again, enter your password, and reconnect fresh. This removes any corrupted saved network settings.

Renew Your IP Address

3

Force a new IP from the router

Go to System Settings → Wi-Fi → Details (next to your network) → TCP/IP tab → Renew DHCP Lease. This requests a fresh IP address from your router, which can resolve connection drops caused by IP conflicts.

4

Delete Wi-Fi preferences files

Open Finder → Go → Go to Folder and type: /Library/Preferences/SystemConfiguration/. Delete these files if present: com.apple.airport.preferences.plist, NetworkInterfaces.plist, and preferences.plist. Restart your Mac — macOS will recreate them fresh.

💡 Mac tip: If your Mac keeps defaulting to 2.4 GHz instead of the faster 5 GHz band, go to Wi-Fi → Details → TCP/IP and check if both bands appear as separate networks. Connect specifically to the 5 GHz network (often listed as "YourNetwork-5G") for a more stable connection.

When to Call Your Internet Provider

Only escalate to your ISP if: your wired Ethernet connection also drops, the router lights are blinking erratically or showing a "no signal" state, or rebooting the modem doesn't help. At that point there may be a line issue on their end.
