You factory reset your router to fix a problem, and now nothing connects to WiFi — phones, laptops, smart home devices. That's because the reset wiped everything: your WiFi name, password, and ISP configuration. Here's how to set everything up again.
Step 1: Connect to Default WiFi
- Check the sticker on the bottom/back of your router
- Find the default SSID (WiFi name) and default password
- On your phone/laptop, look for this network name in available WiFi networks
- Connect using the default password
- Alternative: Connect a computer to the router using an Ethernet cable
Step 2: Access Router Admin Panel
- Open a browser and go to 192.168.1.1 or 192.168.0.1
- Login with default admin credentials (check router label or try admin/admin)
- The setup wizard should start automatically
Step 3: Configure Internet (ISP) Settings
| ISP Type | Connection Type | What You Need |
|---|---|---|
| Cable (Xfinity, Spectrum, Cox) | DHCP / Dynamic IP | Nothing — auto detects |
| DSL (AT&T, CenturyLink) | PPPoE | Username & password from ISP |
| Fiber (Verizon Fios) | DHCP (usually) | Restart ONT if needed |
| Business / Static | Static IP | IP, Subnet, Gateway, DNS from ISP |
Step 4: Set Up WiFi Name and Password
Pro tip: Use the SAME WiFi name and password as before the reset. This way, all your devices (phones, smart speakers, cameras, etc.) will automatically reconnect without needing to be reconfigured.
- In router admin, go to Wireless Settings
- Set SSID (WiFi name) — use the old name if possible
- Set Security to WPA2/WPA3
- Enter your WiFi password — use the old one if possible
- Set up both 2.4 GHz and 5 GHz bands if your router is dual-band
- Save and apply
Step 5: Restart Modem
- Unplug the modem for 60 seconds
- Plug it back in → wait until the Online light is solid (3-5 min)
- The router should now get internet from the modem
Step 6: Reconnect Devices
- If you used the same WiFi name/password: Most devices reconnect automatically — give them 5 minutes
- If you changed the WiFi name/password: Each device needs manual reconnection:
- Phones/laptops: Forget old network → connect to new one
- Smart speakers: Use Alexa/Google Home app to update WiFi
- Smart TVs: Settings → Network → WiFi → select new network
- Cameras: Most need setup from scratch in their app
- Printers: Run WiFi setup wizard using printer's panel or app
Prevention Tip: Back Up Router Settings
Before any future reset or firmware update: Router Admin → System/Administration → Backup Configuration → save the file. You can restore this file after a reset to instantly recover all settings.
Frequently Asked Questions
Why did my WiFi stop working after factory reset?
A factory reset erases ALL settings: WiFi name (SSID), WiFi password, ISP configuration, and security settings. Your devices are still looking for your old WiFi network name/password, which no longer exists. You need to either reconfigure the router with the same settings or update all devices.
How do I find my router's default WiFi after factory reset?
After factory reset, the router broadcasts a default WiFi network. Check: (1) The sticker on the bottom/back of the router — it shows the default SSID (WiFi name) and password, (2) Common default format: 'NETGEAR##', 'TP-LINK_####', 'ASUS_####', (3) The password is usually a randomly generated string on the label.
Do I need to reconfigure my ISP settings after factory reset?
It depends: Cable ISP (Xfinity, Spectrum, Cox): Usually no — DHCP works automatically. Just restart the modem. DSL ISP (AT&T, CenturyLink): YES — you need to re-enter PPPoE username and password. Fiber ISP (Verizon Fios, Google Fiber): Usually auto-detects, but may need modem restart.
How do I reconnect all my smart home devices after factory reset?
This is the biggest pain point. Each device needs to be reconnected individually: (1) Set up the router with the SAME WiFi name and password as before — all devices will reconnect automatically, (2) If that's not possible, you'll need to go through setup on each device: smart speakers, cameras, plugs, TVs, etc.
Can I restore my previous settings after factory reset?
Only if you backed them up: Some routers (Netgear, Asus, TP-Link) have a 'Backup Settings' option in admin panel. You can restore from a backup file. If you didn't back up, all settings are permanently lost and you must reconfigure from scratch.
