How to Reset Your Router Password — Complete Factory Reset Guide

When you've forgotten your router's admin password and cannot log into the web interface, a factory reset (also called a hard reset) is the only way to regain administrative access. This guide covers when to factory reset, the exact procedure for every major brand and model, what happens during the reset, and the steps you must take after the reset to secure your network again. Important: a factory reset erases ALL custom settings — your WiFi name, password, port forwards, firewall rules, and ISP credentials will be lost. Only proceed if you are prepared to reconfigure your network from scratch.

When to factory reset (and when not to)

A factory reset is the right choice when: you bought a used router and don't know the admin password, you changed the admin password and forgot it, the router is acting erratically and power cycling didn't help, you need to clear a configuration that was set by a previous owner or tenant, or you want to start fresh with a clean configuration.

Do NOT factory reset if: you don't have physical access to the router (you need to press the button), you're not sure the router belongs to you or you have permission from the owner, you're not prepared to reconfigure the WiFi name and password afterwards, or you don't have your ISP login credentials (PPPoE username/password, if applicable).

Before resetting: check if any of these easier methods work first: try the default admin password printed on the router sticker, check if the password is saved in your browser's password manager, try common defaults (admin/admin, admin/password), or check if your ISP can reset it remotely.

ISP router note

If your router was provided by your ISP (Comcast, BT, Sky, Vodafone, etc.), the ISP can often reset the admin password remotely or through their mobile app. Call their support line before doing a factory reset — you may avoid the hassle of reconfiguration.

How to factory reset — universal method

All routers follow the same basic procedure: power the router on, locate the Reset port (usually a small recessed hole on the back or bottom), insert a paperclip or SIM eject tool, press and hold for the required time, wait for the router to reboot with factory settings.

The required hold time varies by brand: 10 seconds (TP-Link, D-Link, Tenda, Mercusys), 15 seconds (NETGEAR, Linksys, Zyxel), 30 seconds (ASUS 30-30-30 method: hold Reset while power is ON), 10-15 seconds (Huawei, Xiaomi, MikroTik).

After releasing the button: the router's LEDs will flash or turn off and on. Wait 2-3 minutes for the router to fully reboot and apply factory defaults.

Once rebooted: connect to the router's default WiFi network (name on the sticker) or plug in via Ethernet cable. Go to the default admin IP (usually 192.168.1.1 or 192.168.0.1) and log in with the default admin credentials.

Brand-specific reset procedures

TP-Link: Locate the Reset hole near the power port. With router powered on, use a paperclip to press and hold for 10 seconds. The LEDs flash — release. Wait 2 minutes for reboot. Default admin: admin/admin. Admin IP: 192.168.0.1.

NETGEAR: Reset button on the back panel. Hold for 15 seconds with router powered on. The power LED blinks amber. Release and wait for reboot. Default admin: admin/password. Admin IP: 192.168.1.1.

ASUS: Use the 30-30-30 method — with router powered ON, hold the Reset button for 30 seconds. Keep holding and unplug power for 30 seconds. Keep holding and plug power back in for 30 seconds. Release. Default admin: admin/admin. Admin IP: 192.168.1.1.

Linksys: Press and hold the Reset button for 15 seconds. Release when the power LED starts flashing. Wait 2 minutes. Default admin: admin/admin (no password on older models). Admin IP: 192.168.1.1.

D-Link: Press the Reset hole with a paperclip for 10 seconds. Release when LEDs flash. Default admin: admin/(blank — no password). Admin IP: 192.168.0.1.

Huawei: Press and hold the Reset button for 10 seconds. The indicator flashes. Wait for reboot. Default admin: admin/admin. Admin IP: 192.168.3.1 (or 192.168.1.1).

Xiaomi: Press the Reset hole for 10 seconds with power on. The LED turns orange then blue. Wait for reboot. Admin IP: 192.168.31.1. Set up via Mi Home app.

Ubiquiti UniFi: Reset button on the AP or gateway. Hold for 10 seconds (LED turns white then off). Use UniFi mobile app for initial setup after reset.

MikroTik: Hold the Reset button while powering on until the LED blinks. Release. Default admin: admin/(blank). Admin IP: 192.168.88.1.

Google Nest Wifi: No reset button — factory reset through the Google Home app. Go to WiFi settings > Factory reset. Alternatively, press and hold the button on the bottom of the puck for 10 seconds.

What happens during a factory reset?

A factory reset wipes the router's NVRAM (non-volatile RAM) where the configuration is stored. The firmware, bootloader, and factory calibration data are preserved — the router returns to the exact state it was in when it left the factory.

Settings that are erased: admin username and password, WiFi SSID and password (WPA key), port forwarding rules, firewall rules, QoS settings, DHCP reservations, VPN configuration (if any), ISP login credentials (PPPoE username/password), parental controls, guest network settings, and DNS settings (reverts to ISP defaults).

Settings that are preserved: firmware version (not downgraded by reset), MAC addresses (hardware, not affected), serial number, radio calibration data (transmit power limits, regulatory domain).

After the reset — what you MUST do

Step 1: Connect to the default WiFi (from the sticker) or use a wired Ethernet connection. Open a browser and go to the admin IP.

Step 2: Log in with the default admin credentials (see brand table above). Most routers will prompt you to set a new admin password on first login — use a unique, long password (16+ characters), not the default.

Step 3: Set up your WiFi: choose an SSID (network name) and a WPA2 or WPA3 password. Use a strong password (at least 12 characters, mix of letters, numbers, and symbols). Enable WPA3 if all devices support it.

Step 4: Reconfigure ISP settings: if you have DSL or fiber (PPPoE), enter the username and password from your ISP. Cable modem users (DHCP) usually need no configuration.

Step 5: Reapply any custom settings: port forwarding, static IPs, VPN, QoS, parental controls, guest network, DNS (e.g., Cloudflare 1.1.1.1 or Google 8.8.8.8).

Step 6: Update the firmware. Check the manufacturer's support site or the router's update page for the latest firmware. Always keep firmware up to date for security patches.

Change default credentials immediately

Botnets like Mirai scan the internet for routers still using default admin credentials. Change the admin password to a unique 16+ character string within minutes of first login after a factory reset.

Factory reset vs soft reset vs power cycle

Factory reset (hard reset): Erases all settings and returns the router to factory state. Done by pressing the Reset button for 10-30 seconds. Use when you've forgotten the admin password or need to clear the configuration.

Soft reset: Reboots the router without erasing settings. Done through the admin panel (Settings > Reboot) or by unplugging/replugging power. Use when the router is slow, unresponsive, or has minor issues.

Power cycle: Unplug the router, wait 30 seconds, plug it back in. Same as a soft reset — clears temporary memory but preserves saved settings. Use for minor connectivity issues.

Sequence of effort: Power cycle first, then soft reset via admin panel, then factory reset as the absolute last resort.

Router factory reset procedure

1
Power on the router
Ensure the router is plugged in and fully booted (all LEDs stable).
2
Locate the Reset button
Usually a recessed hole on the back or bottom panel. Labeled 'Reset'. Use a paperclip or SIM eject tool.
3
Press and hold
10 seconds (TP-Link, D-Link), 15 seconds (NETGEAR, Linksys), or 30 seconds (ASUS). Hold until LEDs flash.
4
Release and wait
Release the button. The router reboots. Wait 2-3 minutes for it to finish.
5
Log in with defaults
Connect via Ethernet or default WiFi. Go to admin IP (usually 192.168.1.1). Use default credentials from sticker.
6
Reconfigure the router
Set new admin password, configure WiFi, restore ISP settings, update firmware.

Frequently Asked Questions

Will a factory reset delete my internet connection?

It will erase the router's configuration, including ISP credentials if you use PPPoE. You'll need to re-enter them. Cable internet (DHCP) users usually reconnect automatically.

Does a factory reset change the WiFi password?

Yes. The WiFi password reverts to the factory default printed on the router sticker. You'll need to reconnect all devices with the new/old default password.

How long does a factory reset take?

The reset itself takes 10-30 seconds of holding the button. The router reboot takes 2-3 minutes. Total: about 5 minutes before the router is accessible with factory settings.

Will a factory reset fix a slow WiFi connection?

Usually not. Slow WiFi is typically caused by interference, channel congestion, outdated firmware, or device limitations — not by router configuration. Try changing WiFi channels first.

Can I factory reset a router without the button?

Some models offer factory reset from the admin panel (Administration > Factory Defaults). If you can't log into the admin panel, the physical button is the only way.

Do I need to factory reset a used router?

Strongly recommended. A used router may have unknown configurations, port forwards, or even malware. Reset it, update firmware, and set up from scratch.

Can't find the WiFi password another way?

If every other method failed, capture a WPA handshake on your own network and let our GPU cluster handle the rest. Dictionary + rules attack, 2B+ candidates, pay only on success.
