A factory reset wipes everything — your WiFi name, password, ISP credentials, and all custom settings. Don't panic. In most cases, you can get back online in 10-15 minutes by following these steps.
⚡ Quick Recovery Checklist
- Find default WiFi name & password on router label
- Connect a device using default credentials
- Access admin panel (192.168.0.1 or 192.168.1.1)
- Run setup wizard & enter ISP credentials if needed
- Set new WiFi name & password, reconnect all devices
Fix 1: Find Default WiFi Credentials
- After reset, router uses default WiFi name (SSID) and password
- Check the label on the bottom/back of your router
- Look for: SSID, Network Key, WiFi Password, WPA Key
- The default name is often the router brand + random characters (e.g., "NETGEAR-5G-2A3B")
- If no label, check the manual or manufacturer website
Fix 2: Connect to Default Network
- On your device, go to WiFi settings
- Forget your old network name (it won't work anymore)
- Scan for available networks
- Find the default SSID from the router label
- Connect using the default password from the label
- If WiFi doesn't appear, try connecting via Ethernet cable
Fix 3: Access Router Admin Panel
- Open a browser and type the router's default gateway:
| Brand | Default Admin URL | Default Login |
|---|---|---|
| Netgear | 192.168.1.1 or routerlogin.net | admin / password |
| TP-Link | 192.168.0.1 or tplinkwifi.net | admin / admin |
| Linksys | 192.168.1.1 | admin / admin |
| ASUS | 192.168.1.1 or router.asus.com | admin / admin |
| Xfinity/Comcast | 10.0.0.1 | admin / password |
- Log in with default admin credentials
- Run the setup wizard if prompted
Fix 4: Re-Enter ISP Credentials
If your ISP requires PPPoE login (common with DSL and some fiber providers):
- In the admin panel, go to WAN / Internet settings
- Select connection type: PPPoE
- Enter your ISP username and password
- If you don't have these, call your ISP
- Save and reboot the router
💡 Most cable internet (Comcast, Spectrum, Cox) uses DHCP and doesn't need credentials. DSL (AT&T, CenturyLink) and some fiber providers do.
Fix 5: Set New WiFi Name & Password
- In admin panel, go to Wireless / WiFi settings
- Set a new WiFi name (SSID)
- Choose WPA3 or WPA2 security
- Set a strong password (12+ characters)
- Set up both 2.4GHz and 5GHz bands if available
- Save and wait for the router to restart WiFi
Fix 6: Reconnect All Devices
- On each device, forget the old network
- Scan for your new WiFi name
- Connect with the new password
- Smart home devices (cameras, thermostats) often need reconfiguration via their app
- For printers, re-run the wireless setup on the printer itself
Fix 7: Flush DNS on Your Devices
# Windows
ipconfig /flushdns
ipconfig /release
ipconfig /renew
# Mac
sudo dscacheutil -flushcache
Fix 8: Update Router Firmware
- After re-setup, check for firmware updates in the admin panel
- Usually under Administration → Firmware Update
- Update if available — often fixes bugs that caused the original issue
- Router will reboot after update — don't unplug during update
Fix 9: Contact Support
- If router won't get an internet connection after re-setup
- Call your ISP — they may need to reprovision your modem
- Call the router manufacturer for hardware issues
- Consider if the reset was caused by a deeper hardware failure
Frequently Asked Questions
Why is my WiFi not working after a factory reset?
A factory reset erases all custom settings — your WiFi name (SSID), password, ISP login credentials, DNS settings, and port forwarding rules. If you had ISP-specific settings (like PPPoE credentials), the router can't connect to the internet until those are re-entered. Your devices also need to reconnect with the new default WiFi credentials.
Where do I find my default WiFi name and password after reset?
Check the label on the bottom or back of your router. It shows the default SSID (WiFi name) and password/key. If the label is missing, check the router's manual or the manufacturer's website. For ISP-provided routers, call your ISP for default credentials.
Do I need to set up my router again after factory reset?
Yes. After a factory reset, you need to: (1) Connect via default WiFi or Ethernet, (2) Access the admin panel (usually 192.168.0.1 or 192.168.1.1), (3) Run the setup wizard, (4) Enter ISP credentials if needed, (5) Set a new WiFi name and password. Some ISP gateways auto-configure after a few minutes.
Why can't my devices connect to WiFi after reset?
After reset, the WiFi name and password revert to defaults. Your devices still have the old credentials saved. You need to: (1) Forget the old network on each device, (2) Scan for networks and find the default name, (3) Connect using the default password from the router label, (4) Once you set a new name/password, update all devices again.
My router has internet (lights normal) but WiFi doesn't work after reset. Why?
The internet connection and WiFi broadcast are separate functions. After reset, WiFi may be disabled, set to a different channel your device doesn't support, or broadcasting on a different SSID. Try connecting via Ethernet first, then check WiFi settings in the admin panel at 192.168.0.1 or 192.168.1.1.
