You pressed that tiny reset button hoping to fix a problem, and now your internet is completely gone. A factory reset wipes every custom setting — WiFi name, password, ISP credentials, everything. Here's how to systematically restore your connection.
Step 1: Connect via Ethernet or Default WiFi
- After reset, your router's WiFi name changes to the default SSID (printed on the router label)
- Look at the bottom or back of your router for: default WiFi name, default password, admin URL
- Connect your computer to this default WiFi, or use an Ethernet cable (more reliable)
Step 2: Access Router Admin Panel
Open a browser and go to your router's admin address:
| Router Brand | Admin URL | Default Login |
|---|---|---|
| Netgear | routerlogin.net / 192.168.1.1 | admin / password |
| TP-Link | tplinkwifi.net / 192.168.0.1 | admin / admin |
| Linksys | 192.168.1.1 | admin / admin |
| Asus | router.asus.com / 192.168.1.1 | admin / admin |
| D-Link | 192.168.0.1 | admin / (blank) |
Step 3: Run the Setup Wizard
- Most routers show a setup wizard automatically after reset
- Set your time zone
- For Internet Connection Type, choose correctly:
- DHCP/Automatic — for cable internet (Comcast, Spectrum, Cox)
- PPPoE — for DSL/fiber (AT&T, CenturyLink, Frontier) — requires username/password from ISP
- Static IP — for business connections
- Set a new WiFi name (SSID) and password
- Set a new admin password (don't leave the default)
Step 4: Reconfigure WiFi Settings
- Set WPA3 or WPA2 security (never WEP)
- Choose a unique WiFi name that's easy to identify
- Create a strong password (12+ characters)
- If you have dual-band: set different names for 2.4 GHz and 5 GHz to easily identify them
- After saving, reconnect all devices with the new WiFi password
Step 5: Restart Modem (If Separate)
If you have a separate modem and router, unplug the modem for 60 seconds, then plug it back in. The modem needs to re-register the router's new MAC address. Some ISPs require you to call them to register a new device.
Step 6: Clone MAC Address (If Required)
Some ISPs lock connections to specific MAC addresses. If internet still doesn't work after setup, go to router admin → Advanced → MAC Clone → Clone Current PC's MAC Address. Or call your ISP and ask them to register the router's MAC address.
Prevention: Backup Before Resetting
- Export configuration: Router admin → System → Backup → Save File
- Write down ISP credentials (PPPoE username/password) and keep them safe
- Screenshot your WiFi settings before any reset
- Note your internet connection type (DHCP, PPPoE, Static IP)
Frequently Asked Questions
Why is my internet not working after I reset my router?
A factory reset erases ALL custom settings: (1) WiFi name and password revert to defaults (printed on router label), (2) ISP-specific settings like PPPoE username/password are deleted, (3) Static IP or DNS settings are erased, (4) Port forwarding and custom configurations are gone. You need to reconfigure the router from scratch.
What's the difference between restart and factory reset?
Restart (unplug/replug) = just reboots the router, keeps all settings. Factory reset (hold reset button 10-30 sec) = erases everything and restores original defaults. If you only restarted, your settings are intact. If you factory reset, you need to set up the router again.
How do I find my ISP's PPPoE credentials after a reset?
Contact your ISP (call their support number on your bill). They'll provide: PPPoE username and password (for DSL/fiber connections), or confirm if your connection uses DHCP (automatic — no credentials needed for cable internet). Some ISPs: AT&T, CenturyLink, Frontier use PPPoE. Comcast/Xfinity, Spectrum, Cox usually use DHCP.
Can I backup router settings to avoid this problem?
Yes! Most routers have a backup option: Go to router admin panel → System/Administration → Backup/Restore → Export Configuration. Save the file to your computer. After any future reset, you can import this file to restore all settings instantly.
My ISP router/gateway reset itself — what happened?
ISP gateways can reset due to: (1) Firmware update pushed by the ISP, (2) Power surge, (3) Overheating, (4) Remote reset by ISP during troubleshooting. If this happened without your input, call your ISP — they may need to re-provision the gateway.
